nickwallen commented on issue #1445: METRON-2155 Cache Maven in Travis CI Builds URL: https://github.com/apache/metron/pull/1445#issuecomment-504019653 FYI - I've triggered the CI build on this quite a few times now and at times have cleared the Travis cache associated with the build. On rare occasions some of the jobs fail with this error. No idea why, yet. ``` 0.50s$ [[ -d $M2_HOME ]] || wget -nc -q https://archive.apache.org/dist/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.zip The command "[[ -d $M2_HOME ]] || wget -nc -q https://archive.apache.org/dist/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.zip"; failed and exited with 8 during . ``` https://travis-ci.org/apache/metron/jobs/547316532
