Re: Building JAMES

I’m back to making another attempt at building. :-)

I am not able to update my development machine to use java 11, so I am trying with docker like this:

docker run -it --rm --name my-maven-project -v "$(pwd)":/usr/src/mymaven -w /usr/src/mymaven maven:3.6.3-openjdk-11 mvn clean install


But I quickly run into this problem:

[INFO] Apache James :: Testing :: Base .................... FAILURE [ 38.634 s]

[ERROR] Failed to execute goal pl.project13.maven:git-commit-id-plugin:3.0.1:revision (get-the-git-infos) on project testing-base: Could not complete Mojo execution...: GIT-Command 'git describe --dirty=-dirty --match=* --abbrev=7' did not finish in 30000 milliseconds -> [Help 1]


The plugin doesn’t seem to work in this environment, so I skipped it by adding `-Dmaven.gitcommitid.skip=true` to the run parameters.

Q: Will this cause any problems once I can eventually build successfully?

New result:

[INFO] Apache James Cassandra backend ..................... FAILURE [ 57.902 s]

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.22.2:test (default-test) on project apache-james-backends-cassandra: There are test failures.
[ERROR] 
[ERROR] Please refer to /usr/src/mymaven/backends-common/cassandra/target/surefire-reports for the individual test results.
[ERROR] Please refer to dump files (if any exist) [date].dump, [date]-jvmRun[N].dump and [date].dumpstream.

So I disabled tests and tried again.


The build continues almost to the end (60 minutes on my machine), and unfortunately ends with this:

[INFO] Apache James :: Server :: Web Admin server integration tests :: Common FAILURE [ 12.443 s]

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project james-server-webadmin-integration-test-common: Compilation failure: Compilation failure: 
[ERROR] /usr/src/mymaven/server/protocols/webadmin-integration-test/webadmin-integration-test-common/src/main/java/org/apache/james/webadmin/integration/JwtFilterIntegrationTest.java:[34,33] cannot find symbol
[ERROR]   symbol:   class WebAdminUtils
[ERROR]   location: package org.apache.james.webadmin

Sadly, I still cannot run `mvn eclipse:eclipse`, so I still cannot make any PRs. Looks like I’ll need some help getting started, if that is possible.


Cheers,
