Hi, I'm attempting to build logstash into an RPM. The reason I'm doing this is because I want to include some additional input/output/filter plugins at build time, rather than install them later. My ruby, rake, bundler & gradle skills are not up to scratch. I installed the version of JRUBY that the build was asking for (jruby-9.1.13.0) and have done the following commands: ``` ./gradlew bootstrap ./gradlew build org.logstash.instruments.monitors.MemoryMonitorTest > testEachHeapSpaceRepresented FAILED java.lang.AssertionError: Expected: (a collection containing "PS Survivor Space" and a collection containing "PS Old Gen" and a collection containing "PS Eden Space") but: a collection containing "PS Survivor Space" was "Eden Space", was "Survivor Space", was "Tenured Gen" at org.hamcrest.MatcherAssert.assertThat(MatcherAssert.java:20) at org.hamcrest.MatcherAssert.assertThat(MatcherAssert.java:8) at org.logstash.instruments.monitors.MemoryMonitorTest.testEachHeapSpaceRepresented(MemoryMonitorTest.java:24) ------------------------------------------------------------------------ | Results: FAILURE (508 tests, 507 successes, 1 failures, 0 skipped) | ------------------------------------------------------------------------ 508 tests completed, 1 failed ``` I have no idea if it matters, but my system java is: $ java -version openjdk version "1.8.0\_171" OpenJDK Runtime Environment (build 1.8.0\_171-b10) OpenJDK 64-Bit Server VM (build 25.171-b10, mixed mode) OS is Oracle LInux 7.5 Is anyone able to suggest why the build might be failing and how I could fix it? Many thanks, Nick George ---
