See why travis fails to execute BreakPointHitTestCase #908

Open javierfernandes opened 8 years ago

javierfernandes commented 8 years ago

Something about creating the sockets.

I thought it was because it was executing both tests in parallel, so I made the ports random. Nothing.

I tried to see the logs but they sucks. I tried adding -X -e to .travis.yml mvn command, but the log gets too big and travis won't store it :(

Also tried commenting one test, still fails.

Damn travis !

I noticed that the exception is

So it is not related to sockets but to classloading and the jar dependency to lipermi, which is duplicated in wollok.launch as well as wollok.tests.

Not really sure why it runs fine locally, and in eclipse but not in travis :(
