How to build plugin-based products with platform-specific fragments?

So you want your Tycho build to build 15 distributions just if you reference an Eclipse release train repository?

To me, this seems like a bad idea.

Tobias

Hello,
I have the problem that in my multi platform build with tycho the
platform-specific fragments are missing.
http://wiki.eclipse.org/Tycho/FAQ#How_to_build_plugin-
based_products_with_platform-specific_fragments.3F
Is there no possibility to get around this configuration?
It would be nice if there is an automatic detection of such a case based
on the environment configuration.
Cheers,
Chris

I just noticed that the FAQ you referred had two parts, and the second part has become obsolete: Since https://bugs.eclipse.org/bugs/show_bug.cgi?id=342890 has been fixed, Tycho no longer needs (and in fact ignores) the ws/os/arch attributes in product files.

You obviously still need to specify the ws/os/arch you want to build for in the target-platform-configuration.

Now that this has been simplified, "How to build plugin-based products with platform-specific fragments" should no longer be an FAQ, so I deleted the entry from the FAQ wiki page.

Hello,

I have read the bug, it seems that I need a feature depending product.
I had a plugin based.

Furthermore I had specified which platforms to build like the following:

<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>target-platform-configuration</artifactId>
<version>${tycho.version}</version>
<configuration>
<resolver>p2</resolver>
<pomDependencies>consider</pomDependencies>
<environments>
<environment>
<os>linux</os>
<ws>gtk</ws>
<arch>x86</arch>
</environment>
<environment>
<os>linux</os>
<ws>gtk</ws>
<arch>x86_64</arch>
</environment>
<environment>
<os>win32</os>
<ws>win32</ws>
<arch>x86</arch>
</environment>
<environment>
<os>win32</os>
<ws>win32</ws>
<arch>x86_64</arch>
</environment>
</environments>
</configuration>
</plugin>

But it seems to be ignored in a plugin based product.

Best Regards,

Chris

Hello,

now I have switched to a feature based product, but now I am facing the
same problem.
The platform-specific fragments are missing.

I had setted up the environments like described in my previous mail.
What is going wrong?

Cheers,

We have feature-based products with lots of native code to compile into fragments. Our aggregator has profiles like linux-repo and win-repo and the reactor includes all the plugins (host plugins, fragment plugins, test plugins) and a special platform-specific projects for a feature and a repository. These platform builds only enable the tycho-platform-configuration environment that they're building. So at the end of this reactor each platform build machine has a P2 repo of the native fragments. We copy the windows fragment p2 repo to the linux machine, then build a profile that includes those platform-fragment p2 repos and the reactor has our shippable features and products. And this feature/product reactor has all tycho-platform-configuration environments enabled.

It means we're duplicating the compilation of the Java code on each platform but I couldn't see an easy way to avoid that.

Hello Justin,

thanks for the explaination.
In my case the SWT fragments are missing.

The plugin based way was easy with including all plugins and relation to
the os/ws.
But it isn't the recommened way. So I switched to the feature based
product, because
it should handle all on it own with a valid environment configuration in
the pom.xml.
I have following configuration for the environments:

<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>target-platform-configuration</artifactId>
<version>${tycho.version}</version>
<configuration>
<resolver>p2</resolver>
<pomDependencies>consider</pomDependencies>
<environments>
<environment>
<os>linux</os>
<ws>gtk</ws>
<arch>x86</arch>
</environment>
...
</configuration>
</plugin>

I thought it is enough to define something like that and tycho will use the
fragments, whcih are needed by the environment.
But it seems not to work.

In general I got some problems with the feature based product.
I got after successful build following exception:
java.lang.RuntimeException: Application "org.eclipse.ui.ide.workbench"
could not be found in the registry

I had to include as dependency org.eclipse.ui.ide.application. I don't
know why, but it works after it.

Perhaps I have something wrong in the tycho configuration or similar.

Cheers,

Chris

The problem I ran into with specifying all the platform environments is that if I was on linux building a reactor which included the native fragment bundles it would fail on the windows fragments because the platform filter for those fragments (windows) didn't apply to the OS (linux).

At the moment I only see the possibility to switch back.
Perhaps I miss something out.

I guess I don't know why listing features vs plugins in the product file makes a difference. As long as you have the native fragments for all platforms resolvable and have all the platform environments enabled, the feature should include all of them. The troubles I described were when building the native fragment plugins, not when building the features.

Hmm...

I hope Tobias Oberlies will read our messages. I have added his message.
Okay it seems that the plugin based product supports the behaviour I want.

@Tobias:
"Tycho no longer needs (and in fact ignores) the ws/os/arch attributes
in product files."
In my case I have to specify the attributes otherwise the fragments
aren't added. :/

Tried it again, it doesn't work if I remove the fragment plugin.

If I am using the button add required plugins <plugin
id="org.eclipse.swt.win32.win32.x86" fragment="true"/>
is always added.
Removing it doesn't include it in the build. Furthermore other os/archs
aren't build correctly too.
Placing the plugins like the following works:
<plugin id="org.eclipse.swt.win32.win32.x86" fragment="true"/>
<plugin id="org.eclipse.swt.win32.win32.x86_64" fragment="true"/>

So the statement "Tycho no longer needs (and in fact ignores) the
ws/os/arch attributes in product files."
is correct but you need to put all fragments into the product configuration.

But I don't understand why the system can't use the environment
configurations.
In my opinion it would be a great update.

I think, at the moment, we have to sync our plugin fragments and the

awesome.
Because the developer no longer need to check for which plugins there
are any platform specific fragments.

Yes of course it would be great to have something like that.
I would suggest it as feature request.

What is the opinion about that?

It is a new feature of P2 on the first step, because the resolution should
be the same in all systems.

But there are some problems like: when nobody references fragments, nobody

I understand what you mean, but why you can't determine the fragments
based on the required plug-ins?
For swt I always need <plugin id="org.eclipse.swt"/>. There you can give
a version number, if you need.
Based on that version number and the target environments configured in
the pom.xml you can determine
which fragments are needed.

I understand what you mean, but why you can't determine the fragments
based on the required plug-ins?
For swt I always need <plugin id="org.eclipse.swt"/>. There you can give a
version number, if you need.
Based on that version number and the target environments configured in the
pom.xml you can determine
which fragments are needed.

Then Tycho would need a hard-coded map of environments (and possibly SWT versions) to SWT fragments, and maintain that list. This is just wrong.

The problem needs to be fixed on the SWT side. I had opened a bug for this [1] but it was blocked while there was nobody on the SWT project with enough knowledge of the build system to apply the patch. Maybe this has changed now that the Eclipse platform build has migrated to Tycho...
