»Unknown lifecycle phase "/root/.m2"« when using mvnw

[bmarwell]

Hi!

I tried your images, but I am unable to use mvnw. The wrapper script seems to do a bit too much of magic. The maven image was chosen because I could not find any other image with both git and java installed.

Maven command

      - |
        ./mvnw \
          --show-version \
          --fail-at-end \
          --batch-mode \
          --no-transfer-progress \
          verify \
          site site:stage \
          -Pdocs

Build with --errors does not give any more useful information. https://cloud.drone.io/georgberky/dependency-update-maven-plugin/144/1/2

this means that something is passing $HOME to mvn as argument

I cannot try it because going to the link you provided I cannot clone that commit

[carlossg]

found the PR, the problem is that mvnw takes MAVEN_CONFIG as args, and these images set MAVEN_CONFIG to the .m2 dir

# Provide a "standardized" way to retrieve the CLI args that will
# work with both Windows and non-Windows executions.
MAVEN_CMD_LINE_ARGS="$MAVEN_CONFIG $@"

so you would need to unset MAVEN_CONFIG before calling mvnw

it was reported also as https://issues.jenkins.io/browse/JENKINS-47890

this was actually fixed or mitigated 5 years ago in 0490eff01e529b2d94789511b008d01a7b314953 when using the entrypoint
