[tycho-user] adding plugins

[Luiz Eduardo]

hi all
(thanks to christian) now i got a tycho based project up and running
next step: i need to add eclipselink to my project. how do i do this
with tycho?
on my 'plugin' project, (as i said before, i have 3 projects: plugin,
feature and product) i added this

<dependencies>
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>org.eclipse.persistence.core </artifactId>
<version>2.3.0</version>
<scope>compile</scope>
</dependency>
</dependencies>

but my maven plugin on eclipse says

09/09/11 13h50min31s AFT: Missing artifact
org.eclipse.persistence:org.eclipse.persistence.core:jar:2.3.0:compile
09/09/11 13h50min31s AFT: [WARN] The POM for
org.eclipse.persistence:org.eclipse.persistence.core:jar:2.3.0 is
missing, no dependency information available
09/09/11 13h50min31s AFT: [WARN] The POM for
org.eclipse.persistence:org.eclipse.persistence.core:jar:2.3.0 is
missing, no dependency information available
09/09/11 13h50min31s AFT: Maven Builder: AUTO_BUILD

i'm using a nexus repository on my server.
is this the right path? or should i download eclipselink jars and drop
it on my eclipse folder?

what am i missing?
thanks a lot

Hi again,

well, if you generate your poms using the generate-poms goal, there is
no need for anything like this. Just make sure that the according
plug-in in your workspace has all necessary dependencies (e.g., the
eclipselink stuff), and that your workspace compiles without errors when
the target platform you use within your tycho build is activated. Tycho
will take care of the rest.

The idea is that all information about necessary dependencies is already
contained in the Eclipse metadata (e.g., the plug-ins' manifests) -
tycho "translates" them for maven, so no need to duplicate that
information within the poms.

Hope this helps,
Christian

P.S. I'm quite new to tycho myself, so please take all I say with a
grain of salt. However, I'm pretty sure that the real tycho experts
would jump in if I'm talking bs :-)

hey christian.
thanks again for clarify my path :P

so, i'll keep adding my plug-ins via manifest file, and tycho will take
care of the rest? nice...

another question...about the plug-ins, like, eclipselink. how do you
manage these plug-ins?
i used to drop them inside eclipse/plugins folder and add then via
manifest, but i think this is not right, because i work with a team, and
make them copy my plugins and drop in they plugin folder is not cool.
should i make a folder inside project and add this folder to build path?
VERY THANKS again :)

[Christian Soltenborn]

Hi,

I think this is exactly what target platforms are made for. See e.g.
this article:

http://kaloyanraev.blogspot.com/2011/09/sharing-pde-target-platforms-and-launch.html

Cheers,
Christian

THIS!
exactly what i need!
i've added a folder to my target platform like this:
'${workspace_loc}/project_name/lib' and is this folder, dropped all my
eclipselink plugins, but when i'm trying to add eclipselink plug-ins to
my plugin project as a dependence, it cant found.
am i missing something?
on my eclipse preferences, the target platform points to my platform file
thanks again

[Christian Soltenborn]

Hi,

this is turning into support for an Eclipse feature, and the tycho
mailing list is not the right place for that. Please refer to an
appropriate Eclipse newsgroup for further questions.

As far as I know, the target platform works as follows: Everything added
to a target platform will be automatically downloaded and made available
for the plug-ins in your development workspace as soon as you activate
that target platform. And tycho does the same during your build - one
example of tycho reusing already existing artifacts to make your build
easy to set up.

So there's no need to put those eclipselink plug-ins anywhere inside
your workspace. If you can't add them while your target platform is
active, they are probably not contained in the target platform - check
its content.

Cheers,
Christian

[Luiz Eduardo]

heyy again...
i know i'm being such a pain in the ass, but i want to apply good
practices is this project and any tycho material is pretty scarse. this
list is the only thing that really helps.
again, i got stuck in 'dependencies' problem.

my target definition file look like this:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?pde version="3.6"?>

<target name="Build" sequenceNumber="41">
<locations>
<location path="${workspace_loc}/br.com.german.plugin/lib"
type="Directory"/>
<location includeAllPlatforms="false" includeMode="planner"
includeSource="true" type="InstallableUnit">
<unit id="org.eclipse.rcp.sdk.id" version="3.7.0.I20110613-1736"/>
<unit id="org.eclipse.persistence.jpa.feature.group"
version="2.3.0.v20110604-r9504"/>
<unit id="org.eclipse.persistence.sdo.feature.group"
version="2.3.0.v20110604-r9504"/>
<unit id="org.eclipse.persistence.sdk.feature.group"
version="2.3.0.v20110604-r9504"/>
<repository location="http://download.eclipse.org/releases/indigo/"/>
</location>
</locations>
</target>


as seen, there's a dir '${workspace_loc}/br.com.german.plugin/lib' where
i dropped some plugins (in this case, postgresql driver plug-in)
so, as said, i only need to add plug-ins as dependencies on my MANIFEST.MF

but when i try to 'mvn clean package'...

i'm almost giving up on this :(
it been a week i'm crawling around for a solution :((

[Davy Meers]

Hello,
the problem is that "${workspace_loc}" is an eclipse variable. As far as i know Tycho does not know this variable and uses the text literally. (This causes the warning "[WARNING] Target location type: Directory is not supported")

I do not have a lot of experience with tycho and target platforms. What i did was the following:
1) make sure that i have every dependency in a p2 repository2) in my target platform reference only the p2 repositories
This also meant that for some dependencies which i could not find in a p2 repo, i had to make my own p2 repo and place that on an internal server.It is some extra work but fortunately i didn't have a lot of those dependencies and i could use the target definition with both eclipse pde and tycho.
There might be other options like adding the postgresql dependency to the dependencies section in the pom and add "<pomDependencies>consider</pomDependencies>" to the configuration of the tycho target-platform-configuration plugin (See also https://docs.sonatype.org/display/TYCHO/Dependency+on+pom-first+artifacts).
I think that will be the easiest (maybe the tycho folks can confirm this?).At the time i created the target platform this was not an option because eclipse PDE didn't pick up those dependencies and it was not supported yet in m2e.I think it is supported now by m2e, but i am not sure.
I hope this did help you a bit.
Otherwise feel free to ask your questions.
Regards,Davy

you really helped me :)
but i still have some questions...
the best thing to do in my case is a internal p2 repository, so?
i have a dedicated server, i can do this, but first i must learn how to
do that :P
do you have any link, tutorial or other that can help me trough this?
i'll take a look on add this on my pom (parent pom, right?) actuality i
have a internal repo on nexus. i'll send pom to my nexus, and he'll
download the files i need
thanks guys, you're helping me a lot!

[Davy Meers]

Hi,
I would suggest to try the following first:
1) add the following to your pom dependencies section:

<dependency>
<groupId>org.postgresql</groupId>
<artifactId>com.springsource.org.postgresql.jdbc4</artifactId>
<version>8.3.604</version>
</dependency>
2) Make sure in the plugin section that you have minimum the following:

<plugin>
<groupId>org.sonatype.tycho</groupId>
<artifactId>target-platform-configuration</artifactId>
<version>${tycho-version}</version> <!-- Make sure this property is defined or replace it with the tycho version you use-->
<configuration>
<resolver>p2</resolver>
<pomDependencies>consider</pomDependencies>
</configuration>
</plugin>
3) Make sure the springsource repositories are present in the repositories section of the POM:

<repository>
<id>com.springsource.repository.bundles.release</id>
<name>SpringSource Enterprise Bundle Repository - SpringSource Bundle Releases</name>
<url>http://repository.springsource.com/maven/bundles/release</url>
</repository>

<repository>
<id>com.springsource.repository.bundles.external</id>
<name>SpringSource Enterprise Bundle Repository - External Bundle Releases</name>
<url>http://repository.springsource.com/maven/bundles/external</url>
</repository>
4) Try to build it

If this does not work out i would suggest to create an internal P2 repository (Note: this is not the same as a Maven repository)

hi!

i added this to my plugin pom:

<dependency>
<groupId>postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>9.0-801.jdbc4</version>
</dependency>

and my parent pom is like

<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>target-platform-configuration</artifactId>
<version>0.12.0</version>
<configuration>
<resolver>p2</resolver>
<pomDependencies>consider</pomDependencies>


maven has downloaded the postgre driver, its listed on Maven
Dependencies of my project. but when i try do compile with 'mvn clean
package', the following error occours:

1. ERROR in
C:\Java\workspaceRCP\br.com.german.plugin\src\br\com\german\plugin\A
ctivator.java (at line 6)
import org.postgresql.Driver;
^^^^^^^^^^^^^^
The import org.postgresql cannot be resolved

am i missing something?

[Davy Meers]

The reason is that the dependency you are using ("postgresql:postgresql:9.0-801.jdbc4") is not OSGi-compatible (if you look at the manifest you will see that no packages are exported).That is the reason why i told you to use the dependency "org.postgresql:com.springsource.org.postgresql.jdbc4:8.3.604" from the springsource repository: it is OSGi-compatible (the needed packages are exported).

hmm, got it...
but m2e says '13/09/11 12h7min3s GMT: Missing artifact
org.postgresql:com.springsource.org.postgresql.jdbc4:jar:8.3.604:compile'

i added the repositories to my plugin pom, and tried to add them to
settings.xml. none os them worked :(

[Davy Meers]

Hello,
Can you check your maven settings? Make sure you do not have a catch-all mirror setup.
Something like:
<mirror> <!--This sends everything else to nexus --> <id>nexus</id> <mirrorOf>*</mirrorOf> <url>someurl</url> </mirror>
I also created a minimal OSGi project that uses the postgresql dependency. (I have no problems building it with the default maven settings)Have a look at https://github.com/mudelta/Tycho-Example-PomDependencies

hey :)
here are my settings.xml: https://gist.github.com/1216325
i'll take a look into your project.
but why are you using variables like $project_loc if you said that tycho
doesn't recognize they?
thanks a lot :)

You are using a nexus server as a mirror:
<mirror> <id>nexus</id> <mirrorOf>*</mirrorOf> <url>http://192.168.0.10:8080/nexus/content/groups/public/</url></mirror>
The following repositories have to be added to nexus. You have to ask this to the administrator of the nexus server.
<repository>
<id>com.springsource.repository.bundles.release</id>
<name>SpringSource Enterprise Bundle Repository - SpringSource Bundle Releases</name>
<url>http://repository.springsource.com/maven/bundles/release</url>
</repository>

<repository>
<id>com.springsource.repository.bundles.external</id>
<name>SpringSource Enterprise Bundle Repository - External Bundle Releases</name>
<url>http://repository.springsource.com/maven/bundles/external</url>
</repository>

I suggest you remove the gist because it contains your password for your proxy server.

About the $project_loc:
Tycho will use the dependency from the pom and ignore the $project_loc (it will issue a warning though).The problem is neither M2E (with the Tycho extension) nor PDE pick up the dependency from the POM. This means you still need that jar in your lib folder and link to it from within your target platform.Otherwise you will get problems in your eclipse environment.

i've already added this repository to my nexus server...i'ts working now...
in m2e, i've enabled dependeceny management, and now, when i add the
following dep. to my pom:
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>javax.persistence</artifactId>
<version>${javax.persistence.version}</version>
</dependency>

m2e downloads my javax.persistence jar, and drops him inside 'Maven
Dependencies' lib. same goest to postgresql driver and eclipselink jars.

now i added the 'lib' folder to my target platform, but when i try to
start my app:

... 34 more

i'm using com.springsource.org.postgresql.jdbc4-8.3.604 jar
seems like eclipse doesn't recognize my libs folder or something...

my target:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?pde version="3.6"?>

<target name="Germantech" sequenceNumber="51">
<locations>
<location includeAllPlatforms="false" includeMode="planner"
includeSource="true" type="InstallableUnit">
<unit id="org.eclipse.rcp.sdk.id" version="3.7.0.I20110613-1736"/>
<repository location="http://download.eclipse.org/releases/indigo/"/>
</location>
<location path="${project_loc}/lib" type="Directory"/>
</locations>
</target>

when i try mvn clean install, tycho still can't find my libs

[INFO] Compiling 8 source files to

(at line 3)
import javax.persistence.Persistence;
^^^^^^^^^^^^^^^^^
The import javax.persistence cannot be resolved

but now, i feel like i'm getting the point :) things are getting clear
around my head :)
i'm excited with what i'll be able to do with these things :P
thanks a lot

I am not sure about the target platform in eclipse. Are the target platform file and the lib folder contained in the same project?(Note that that problem is not really a Tycho problem and it does not really belong on this list).
About the dependency org.eclipse.persistence:javax.persistence:
It is not available in the Maven Central repository. You have to add the EclipseLink repository to your nexus: http://download.eclipse.org/rt/eclipselink/maven.repo
See also http://stackoverflow.com/questions/3122135/cant-find-the-org-eclipse-persistence-maven-dependency and http://wiki.eclipse.org/EclipseLink/Maven

yep, target platform and lib folder are on the same project...
now, i'm facing another problem, but this one is eclipse related :)
gonna try eclipse forums
thanks for the help, i'll keep trying here :)

cheers
