Ed Randall commented on MPMD-39:
--------------------------------
maven-pmd-plugin should be
[toolchains-aware|https://maven.apache.org/guides/mini/guide-using-toolchains.html]
and pick up the correct JDK used for compilation.
If toolchains is in use, it should not use the same JDK that maven is running.
We have an enterprise build system when maven runs under JDK 1.8. Some
projects target 1.8, others target 11. PMD cannot cope with 11 code when it's
running under 8 and when the target is 11, we are forced to set
typeResolution=false, to avoid all sorts of strange errors (eg. 'unused private
method' despite it being used 28 times in the same class).
> Target JDK should default to configuration of the compiler plugin
