How to compile all maven modules even if tests fail, but fail overall build if any tests fail

Question

Context: I want to compile and test all modules in a multi-module project but if any fail either compilation or tests I want the overall build to fail.

Default configurations either stop on the first failure or skip modules after a test failure

Running:

mvn clean install

stops at the first failing module.

If you add:

mvn clean install -fae //fail at end

then all modules are run, but if tests fail then any dependent modules are skpped:

    [INFO] ------------------------------------------------------------------------
    [INFO] Reactor Summary:
    [INFO] ------------------------------------------------------------------------
    [INFO] Module A ............................................. SUCCESS [15.210s]
    [INFO] Module B ............................................. SUCCESS [10.923s]
    [INFO] Module C ............................................. FAILED [1.731s]
    [INFO] Module D ............................................. SUCCESS [3.791s]
    [INFO] Module E ............................................. SUCCESS [1.488s]
    [INFO] Module F ............................................. SKIPPED (dependency build failed or was skipped)
    [INFO] Module G ............................................. SKIPPED (dependency build failed or was skipped)
    [INFO] Module H ............................................. SKIPPED (dependency build failed or was skipped)
    [INFO] Module I ............................................. SUCCESS [1.690s]
    [INFO] -----------------------------------------

Another option to force all modules to compile is:

mvn clean install -fn //fail never

but this results in the build passing when tests fail

Can anyone advise a set of options to achieve the following:

1. compile all modules
2. run tests on all modules
3. If a module's tests fail but the code compiles dependent modules still get compiled and tested

Responses much appreciated - otherwise we have to run the tests repeatedly on the build server if there are multiple issues - burning a lot of time.

Answer 1

I would suggest to use:

mvn -Dmaven.test.failure.ignore=true --fail-at-end clean install

Answer 2

I would suggest to split it into two mvn calls:

mvn clean compile
mvn -fae install

The first call will fail, if there are compile errors. The second call will reuse the compiled .class-files, since "clean" is omitted. It will fail at the end, if there are test failures. But compilation has already been finished for ALL modules.
