Problem building efxclipse sample app with tycho and Java 8 [message #1257606]

Hi,

I come into trouble when trying to build the e4 sample application with tycho (0.19.0) and java 8.
I setup a parent pom and a pom for the plugin, feature and product. The build is configured against the http://download.eclipse.org/efxclipse/runtime-released/0.9.0/site/ target platform

when launching an mvn install, I get the following error :

[INFO] Scanning for projects...

The thing about jre 1.6.0 seems curious,
Any clue on what's happening ?

No - i have to try myself - it looks like the problem is the same as if
you are not unchecking "include required ...." in the target platform
setting.

I'll give it a try tomorrow myself - can you try with tycho 0.18?

Well tycho 0.18 does not seem to support JavaSE-1.8 execution environment:

[ERROR] Internal error: org.eclipse.tycho.core.osgitools.OsgiManifestParserException: Exception parsing OSGi MANIFEST C:
\Users\Guest\dev\workspace\DemoApplication\META-INF\MANIFEST.MF: Unknown OSGi execution environment: 'JavaSE-1.8' -> [He

environment: 'JavaSE-1.8'

I also followed the instructions to include the Java 1.8 JDT beta libs and configure the tycho-compiler-plugin to use them as described in the following post:

https://dev.eclipse.org/mhonarc/lists/tycho-user/msg05279.html

but without better result.

This morning I gave a try with tycho 0.20.0-SNAPSHOT (http://wiki.eclipse.org/Tycho/Release_Notes/0.20)

The 1.6.0 dependency problem looks fixed, but now I somehow have to tell the compiler plugin how to properly resolve the jdt 1.8 libs because it tries to resolve them in the tycho 0.20.0-SNAPSHOT plugin repository instead of my local m2 repo :

Hi,

Well i think you now have a compiler which understands Java8 but that
does not mean the p2-director shipped with it knows how to deal with the
1.8 EE hence the error with installing stuff.

Finally the last error was just because my script that deploys the 1.8 JDT libs in my local repo was buggy, that's why it could not resolve the dependency.

Now everything works fine, tycho (0.20.0-SNAPSHOT) successfully generates the efxclipse sample application product with jdk 8.
