You can edit the build.gradle to customize the native library build process.
./gradlew gen --parser-name=<parser name> --parser-version=<parser version> --parser-zip=<parer zip download url>
# build native library
./gradlew tree-sitter-<parser name>:buildNative
# run tests
./gradlew tree-sitter-<parser name>:test
