I am working on Ubuntu 16.04 LTS. My colleagues are building the same project without any problem, it works even on Jenkins CI. What is the problem here? The filename is 144 chars long, which should be fine, ext has limit of 255 charactes.

Answer 1

The problem is, I have encrypted home directory and Ubuntu allows filename only 143 chars long:

From one of authors of eCryptfs:

Empirically, we have found that character filenames longer than 143 characters start requiring >255 characters to encrypt. So we (as eCryptfs upstream developers) typically recommend you limit your filenames to ~140 characters. https://unix.stackexchange.com/a/32834/82647

So options basically are:

• Make filename shorter by renaming methods and classes
• Move your project outside encrypted directory
• Remove encryption of your home directory

Answer 2

you can always disable file reporting via pom.xml file or console parameters

mvn clean install -Dsurefire.useFile=false -DredirectTestOutputToFile=false -DdisableXmlReport=true

Test results will be logged to console

Other way (untested by me) would be aggregating report, mentioned here maven surefire reporting plugin configuration
