[tycho-user] Any workaround for feature patches?

[Hussein, Mohamed]

Hi,

I have been working on converting the build of an RCP product we have from PDE build to Tycho (yes, that late, sorry :))

It is all working well, this mailing list, stackoverflow and the wonderful tutorials online are all great (Thanks everyone for the great help), until I started adding our platform feature patches to the build.
I started getting errors like

[DEBUG] No solution found because the problem is unsatisfiable.: [Unable to satisfy dependency from org.eclipse.equinox.p2.core.feature.feature.group 1.3.100.v20150527-1706 to org.eclipse.equinox.p2.core [2.4.0.v20150527-1706].; Unable to satisfy dependency from org.eclipse.platform.feature.group 4.5.2.v20160212-1500 to org.eclipse.debug.ui [3.11.101.v20160203-1230].; Unable to satisfy dependency from org.eclipse.platform.feature.group 4.5.2.v20160212-1500 to org.eclipse.ui.navigator [3.6.0.v20150422-0725].; Unable to satisfy dependency from org.eclipse.platform.feature.group 4.5.2.v20160212-1500 to org.eclipse.ui.navigator.resources [3.5.1.v20160128-1644].; Unable to satisfy dependency from org.eclipse.rcp.feature.group 4.5.2.v20160212-1500 to org.eclipse.ui.workbench [3.107.1.v20160120-2131].; No solution found because the problem is unsatisfiable.]

I started searching online and hit few open[1] bugs[2] and emails sent here before[3] and questions on stackoverflow[4], but I didn't find a solution or a workaround, or my lack of experience in tycho didn't allow me to understand if there is a valid one.
Though it seems that the open issues are old, so definitely those who have faced this have moved forward.

Can someone please point me to a solution or a workaround to be able to build and include eclipse feature patches with tycho?

Best Regards,
Mohamed.

I just have some pointers, since I was interested in the topic a while ago:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=497840 explains a bit how the
JDT feature patches for beta support for new Java versions are built
Groovy-Eclipse also builds a feature patch into their repository, so you
could look at that too: https://github.com/groovy/groovy-eclipse

WOW, Thanks a lot Felix,

I tried reading through both the bugzilla and groovy pom files, but it was too much Klingon for my simple early-morning-before-coffee brain ☺ I will try to give it a deeper look and do some trials.

One thing that caught my eye is this:
I think the "Tycho recommendation" is to do it in two steps. First "build everything" with the desired fix, and save away the repository locally (by which I think they mean the maven repository). So you'd need to do some sort of mvn clean deploy, instead of a simple mvn clean verify as we normally do. Then, second step, do a completely separate build of your feature patch, which makes use of the locally deployed maven repo from the first step so it "picks up" only what you need.


Is there a simple example that shows this in practice, or a place where it is documented?
Also, any thoughts on the cons of this approach that triggered the seemingly more complex approach outlined in the bugzilla.

Best Regards,
Mohamed.
