Using Java preview features
In order to analyze a project with PMD that uses preview language features, you’ll need to enable
it via the environment variable PMD_JAVA_OPTS and select the new language version, e.g. 20-preview:
export PMD_JAVA_OPTS=--enable-preview
./run.sh pmd --use-version java-20-preview ...
Note: we only support preview language features for the latest two java versions.
Note: --use-version is only supported since PMD 6.52.0. Older versions of PMD use two CLI options that have to
be specified together: -language java -version 20-preview.
