dweiss commented on issue #1138: LUCENE-9077 Print repro line for failed tests URL: https://github.com/apache/lucene-solr/pull/1138#issuecomment-570797460 Hi Mike. I looked at gradle's internal APIs again and I don't think we'll be able to dodge having a custom test output listener. I would rather have it complete two goals at once: emit test failure information and dump test output on failure. This has been done by Elasticsearch under this issue: https://github.com/elastic/elasticsearch/issues/31496 The discussion there is enlightening about certain aspects of handling gradle's output. We can also borrow some of the code (like ErrorReportingTestListener.java that buffers up test output and discards it if the test passes). I believe some changes would have to be implemented -- Solr tests emit *TONS* of output and it will lead to OOM exceptions of the build system... It should spill to disk after it reaches a certain threshold. But even the in-memory version would be a start. Would you be willing to bite into this (borrowing some code from ES)?
