PomInlinerTransformer: Cannot inline property 'revision' (CI-friendly version)

[gnodet]

Summary

When a project uses CI-friendly versions (${revision} property in <version>), Maven 4's PomInlinerTransformer fails with IllegalArgumentException: Cannot inline property revision.

Reproduction

Projects affected (found in maven4-testing rc-6 run):

• hbase-operator-tools
• hugegraph-toolchain

Both use ${revision} in their <version> element and work fine with Maven 3.

Expected behavior

CI-friendly version properties (${revision}, ${sha1}, ${changelist}) should be correctly inlined when generating the consumer POM — the same way they are when set on the command line via -Drevision=1.0.0.

Actual behavior

Build fails with Cannot inline property revision.

Maven version

Maven 4.0.0-rc-6 / maven-4.0.x branch
