[Rob Stryker (JIRA)]

Rob Stryker created JBIDE-19881:
-----------------------------------

             Summary: Servertools local build failing with very strange errors
                 Key: JBIDE-19881
                 URL: https://issues.jboss.org/browse/JBIDE-19881
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: build, server
            Reporter: Rob Stryker


So I tried to run my servertools build while making a patch for https://issues.jboss.org/browse/JBIDE-19801

And I started getting very very weird errors:

http://fpaste.org/226368/32788687/

Nick instructed me to check if my build was using Java8, and it wasn't.  Somehow it was still using java7.  

So next, I export JAVA_HOME to a java8 installation, and I get a newer weirder error:

{code}

I come to find out that the jacoco we're using is  org.jacoco.agent/0.6.1.201212231917.  This was released, obviously by timestamp, in 2012.  I find https://github.com/jacoco/jacoco/issues/74  which was a bug fixed in 2013, after our current jacoco.   So if we must now run with java8, then clearly we need a newer jacoco. 

Either way, it seems that either my machine is very messed up, or there's a lot of weird stuff changing on build side that's not matching each other. 

No idea how to fix either bug ;)
