Plugins: Running ./gradlew run in external plugins fails

[spinscale]

Elasticsearch version (bin/elasticsearch --version): 6.3.2 (all of 6.3 is affected), works in 6.2 and below

When trying to call ./gradlew run in an external plugin, the following exceptions pops up

./gradlew run

It seems that the correct artifact would be the elasticsearch-oss distribution at https://repo.maven.apache.org/maven2/org/elasticsearch/distribution/zip/elasticsearch-oss/6.3.2/elasticsearch-oss-6.3.2.zip

If you want to reproduce you can run

# this will create an ingest plugin skeleton in the ingest-awesome directory
cookiecutter --no-input gh:spinscale/cookiecutter-elasticsearch-ingest-processor
cd ingest-awesome
./gradlew run

I think this has already been addressed by #32549?

[spinscale]

indeed, fixed in 6.4.0
