Hi all
I wanted to see whether anything was broken in COMPRESS with the Java10
RC or the EA version of Java11 - unfortunately the build fails with
NullPointerException inside of Surefire.
I run
$ mvn clean test '-P!jacoco'
as Jacoco doesn't seem to work for Java10+ either. I end up with
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-surefire-plugin:2.20.1:test (default-test) on
project commons-compress: Execution default-test of goal
org.apache.maven.plugins:maven-surefire-plugin:2.20.1:test failed.:
NullPointerException -> [Help 1]
[ERROR]
The stack trace I see with -X gets me to
Caused by: java.lang.NullPointerException
at
org.apache.maven.surefire.shade.org.apache.commons.lang3.SystemUtils.isJavaVersionAtLeast(SystemUtils.java:1626)
which I'm afraid has just been fixed a few days ago for Java11.
IIUC this means it is impossible to run tests with Maven on Java11+ at
all until we (1) cut a new release of LANG and (2) get Surefire to use
that.
For Java10 I'd probably need to force Surefire to use LANG in version
3.7 (which according to the changelog fixes the NPE). I thought I'd add
an explicit dependency on lang 3.7 inside pluginManagement. Doing so I
see maven download LANG 3.7 but I still run into the same NPE. Obviously
Surefire does still use a different version of LANG as the line number
for the NPE is still the same, but this is a comment line inside the 3.7
tag.
Here is what I tried in COMPRESS' pom and still get the NPE with Java10:

Any ideas?
