Incorrect encoding for JMH output

[sergey-morenets]

Hi

I tried to use JMH Gradle plugin for my project but JMH prints weird question marks instead of correct numbers (Gradle 4.3.1, command gradle jmh):

Benchmark                                            (provider)  Mode  Cnt   Score    Error  Units
FieldProviderBenchmark.getFieldNames_targetCityCopy       Basic  avgt   20  ? 10??            s/op
FieldProviderBenchmark.getFieldNames_targetCityCopy      Cached  avgt   20  ? 10??            s/op

However jmh-result.text generated during this build looks correct:

Benchmark                                            (provider)  Mode  Cnt     Score    Error  Units
FieldProviderBenchmark.getFieldNames_targetCityCopy       Basic  avgt   20  1140,589 ± 11,138  ns/op
FieldProviderBenchmark.getFieldNames_targetCityCopy      Cached  avgt   20   127,683 ±  0,923  ns/op

I tried to change default JVM encoding but the issue still reproduces:

jmh {
  jvmArgs = '-Dfile.encoding=UTF-8'
}

Please advise.

Hi @melix

Any progress on this? This issue still reproduces with Gradle 4.8 and plugin version 0.4.7
