## 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. `19-preview`:

    export PMD_JAVA_OPTS=--enable-preview
    ./run.sh pmd --use-version java-19-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 19-preview`.
