EclEmma v3 with Target 3.8

[rvea...@gmail.com]

Since EclEmma still has target 3.8 file in it's repository, I am trying to build the plugin (v3.0.0) for that version of Eclipse but `mvn install` is failing.
Does anyone know how to fix this? For reasons I can't upgrade my eclipse version.
If this target isn't supported anymore, shouldn't it be removed from the repository?

Here is the output:

Hi,

Unfortunately target file in EclEmma v3.0.0 points to latest builds of Orbit repository whose content changes over time - https://github.com/eclipse/eclemma/blob/v3.0.0/org.eclipse.eclemma.target/eclemma-e3.8.target#L18

Change this line to use released Orbit repository that contains required ASM, JaCoCo and JUnit versions, and build will go fine - e.g. http://download.eclipse.org/tools/orbit/R-builds/R20170307180635/repository/

Or simply build latest master. BTW out of curiosity - why do you need to rebuild historical version instead of building latest master?

Regards,

Evgeny

Thanks, both are compiling just fine now.

I was using an older version before, and I believe I was just trying a version upgrade at a time instead of jumping straight to the latest. The one before 3 compiled fine, but the one after didn't. I don't think I even tried master before anything else.

Thanks for your help.
