             Summary: gradle precommit sometimes fails with "IOException: stream closed" from javadoc in nightly benchmarks
                 Key: LUCENE-9670
                 URL: https://issues.apache.org/jira/browse/LUCENE-9670
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Michael McCandless


I recently added tracking how long {{gradle precommit}} takes each night so we can track slowdowns over time.

But it sometimes fails with:
{noformat}
> Task :lucene:join:renderJavadoc FAILED
Could not read standard output of command '/opt/jdk-15.0.1/bin/javadoc'.

I'm not sure why ... when I run {{./gradlew precommit}} interactively it doesn't seem to do this.

The nightly tool is quite simple – it just launches a sub-process using {{os.system}}: (first to {{git clean}} then to run {{./gradlew precommit)}}: https://github.com/mikemccand/luceneutil/blob/master/src/python/runNightlyGradleTestPrecommit.py
