Description:
|
Builds with surefire on Windows OS prevent deletion of files with output from tests. These files are created when [maven.test.redirectTestOutputToFile|http://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html#redirectTestOutputToFile] is activated.
There is a known problem with memory mapped io on windows os:
"[...] Windows does not allow a mapped file to be deleted [...]"

_[hudson.tasks.junit.SuiteResult|https://github.com/jenkinsci/jenkins/blob/734e7e01306e1696655e619d8902a7e6e98b4315/core/src/main/java/hudson/tasks/junit/SuiteResult.java]_ uses memory mapped io to read the redirected test output.
I have attached a patch ([^noMemoryMappedIoForWindows-V2.patch]), that reactivates an older implementation without memory mapped io on windows. I think this patch is only a temporary solution, because it reintroduces a memory problem. This problem was [solved|https://github.com/jenkinsci/jenkins/blob/fe934aac007a20c43e803de61ef8b6cf28c4434f/core/src/main/java/hudson/tasks/junit/SuiteResult.java] with memory
mapped io.
