Andrew Potter commented on SUREFIRE-1422:
-----------------------------------------
I tried again with the latest version of alpine, and it looks like that
version's default ps fails on the -p flag instead of ignoring it. You can see
for yourself by running the container:
{code:java}
$ docker run -it alpine
/ # /bin/ps -o etime= -p 1
/bin/ps: unrecognized option: p
BusyBox v1.27.2 (2017-12-12 10:41:50 GMT) multi-call binary.
Usage: ps [-o COL1,COL2=HEADER]

> Forking fails on Linux if /bin/ps isn't available

> Key: SUREFIRE-1422
> URL: https://issues.apache.org/jira/browse/SUREFIRE-1422
> Project: Maven Surefire
> Issue Type: Bug
> Components: process forking
> Affects Versions: 2.20.1
> Environment: Linux (Debian 9 with OpenJDK 8)
> Reporter: Emmanuel Bourg
> Assignee: Tibor Digana
> Priority: Major
> Fix For: 2.21.0
>
>
> Hi,
> With the changes introduced by SUREFIRE-1302 I'm now experiencing a failure
> on Linux when the fork mode is enabled:
> {code}
> [ERROR] Failed to execute goal
> org.apache.maven.plugins:maven-surefire-plugin:2.20.1:test (default-test) on
> project foo: There are test failures.
> [ERROR]
> [ERROR] Please refer to /foo/target/surefire-reports for the individual test
> results.
> [ERROR] Please refer to dump files (if any exist) [date]-jvmRun[N].dump,
> [date].dumpstream and [date]-jvmRun[N].dumpstream.
> [ERROR] The forked VM terminated without properly saying goodbye. VM crash or
> System.exit called?
> {code}
> I traced the issue back to the PpidChecker class, the code assumes that
> {{/bin/ps}} or {{/usr/bin/ps}} exist but this isn't guaranteed (especially on
> trimmed down containers commonly used for continuous integration).
> It would be nice to have a fallback mechanism when ps isn't available, or at
> least check its existence and display an explicit message stating that it
> must be installed.
