surefire plugin by default spins off a new jvm, you can configure surefire
plugin's "forkMode" to none

Thank you for your answer. I tried setting it like this, but this did
not work, maybe because of this here:
[WARNING] Failed to initialize environment variable resolver. Skipping
environment substitution in settings.
So i changed it directly in the file /usr/local/maven/bin/mvn, by
changing
exec "$JAVACMD" \
$MAVEN_OPTS \
-classpath "${M2_HOME}"/core/boot/classworlds-*.jar \
"-Dclassworlds.conf=${M2_HOME}/bin/m2.conf" \
"-Dmaven.home=${M2_HOME}" \
${CLASSWORLDS_LAUNCHER} $QUOTED_ARGS
to
exec "$JAVACMD" -Xmx512m \
$MAVEN_OPTS \
-classpath "${M2_HOME}"/core/boot/classworlds-*.jar \
"-Dclassworlds.conf=${M2_HOME}/bin/m2.conf" \
"-Dmaven.home=${M2_HOME}" \
${CLASSWORLDS_LAUNCHER} $QUOTED_ARGS
Now mvn is starting, but it really seems like I don't have enough
memory:

So I tried it with -Xmx32m as my provider told me to do so, but then I
get:
[INFO] [surefire:test]
[INFO] Surefire report
directory: /home/autobuild/modules/sudokusolver/target/surefire-reports

I think the surefire-report does not get the -Xmx32m argument?
Do you have another hint for me how I could fix this?
Thank you
Elias
