how to reproduce:

% git clone git@github.com:jdbi/jdbi
% cd jdbi
% git checkout v3.38.0-rc3
% mvnd -pl :jdbi3-core -am clean install

Same command with mvn works fine.

Given the way our project sets module names (we use per-module profile activation based on the presence and absence of files in the directories), the most likely culprit is some sort of caching of profile activation. The correct list of profile activations would be:

Active Profiles for Project 'org.jdbi.internal:jdbi3-policy:jar:3.38.0-rc3':

The following profiles are active:




Active Profiles for Project 'org.jdbi.internal:jdbi3-build-parent:pom:3.38.0-rc3':

The following profiles are active:

 - in-parent (source: org.jdbi.internal:jdbi3-build-parent:3.38.0-rc3)
 - macos arm (source: org.jdbi.internal:jdbi3-build-parent:3.38.0-rc3)



Active Profiles for Project 'org.jdbi:jdbi3-parent:pom:3.38.0-rc3':

The following profiles are active:

 - java17 (source: org.jdbi:jdbi3-parent:3.38.0-rc3)
 - in-parent (source: org.jdbi.internal:jdbi3-build-parent:3.38.0-rc3)
 - macos arm (source: org.jdbi.internal:jdbi3-build-parent:3.38.0-rc3)



Active Profiles for Project 'org.jdbi:jdbi3-core:jar:3.38.0-rc3':

The following profiles are active:

 - java17 (source: org.jdbi:jdbi3-parent:3.38.0-rc3)
 - macos arm (source: org.jdbi.internal:jdbi3-build-parent:3.38.0-rc3)
 - basepom.invoker-reporting (source: org.basepom:basepom-oss:52)
 - basepom.invoker-integration-testing (source: org.basepom:basepom-foundation:52)

The in-parent profile provides a module name. Running the same command with mvnd yields no output (!).

pretty ping?

Quick update: I built the current trunk from scratch with

openjdk 17.0.6 2023-01-17
OpenJDK Runtime Environment GraalVM CE 22.3.1 (build 17.0.6+10-jvmci-22.3-b13)
OpenJDK 64-Bit Server VM GraalVM CE 22.3.1 (build 17.0.6+10-jvmci-22.3-b13, mixed mode, sharing)

and tried both the m39 and m40 variants. Same result. So this is a problem that still exists in the current version and it is not confined specifically to maven 3.9 or maven 4.0

[hgschmie]

This also fails only with the smart builder. When using --builder=singlethreaded or --builder=multithreaded, the build succeeds.

[electrum]

@hgschmie thanks for tracking this down and filing the issue. We've been hitting this as well. I can confirm that putting mvnd.builder=multithreaded in my ~/.m2/mvnd.properties file works around the issue for me.

[gnodet]

So this problem is caused by a combination of two factors:

• mvnd caches the realm, this is usually not a problem, but it is in the case of enforcer
• the problem happens only if the modules are built in a given order

What happens is that when the first module is built, the enforcer loads the rules, including the requireProperty one. The first execution works fine. However, during the second execution, the enforcer does not reload the rules, thereby executing the rule which should not be configured, hence the failure.

[gnodet]

My analysis was wrong. The problem seems to come from the MavenSession injected into plexus components for the enforcer realm, which does not point to the correct project.

The fix is available at takari/takari-smart-builder#25
