Merging MAVEN_ARGS buggy

[hohwille]

Actual behavior

IDEasy is supposed to set two additional things into MAVEN_ARGS variable:

1. -s $IDE_HOME/conf/mvn/settings.xml
2. -Dsettings.security=$IDE_HOME/conf/mvn/settings-security.xml

With story #1238 this should remain even when the user explicitly sets MAVEN_ARGS in his ide.properties.
As discussed in review of PR #1825 the merging of the MAVEN_ARGS property value should "override" potential other settings of 1. (-s ...) or 2. (-Dsettings.security=...).
Retest showed that this is not working. I got this from the reproducer:

-Xmx8000m -s invalid/settings.xml -Dsettings.security=something_wrong -s D:\projects\IDEasy\conf\mvn\settings.xml -Dsettings.security=D:\projects\IDEasy\conf\mvn\settings-security.xml

Reproduce

1. icd -p IDEasy
2. echo 'export MAVEN_ARGS="-Xmx8000m -s invalid/settings.xml -Dsettings.security=something_wrong"' >> conf/ide.properties
3. ide
4. echo $MAVEN_ARGS

Expected behavior

something like this:

-Xmx8000m -s D:\projects\IDEasy\conf\mvn\settings.xml -Dsettings.security=D:\projects\IDEasy\conf\mvn\settings-security.xml

Comments/Hints

Simply strip any arguments starting with -Dsettings.security= as well as -s followed by anything from MAVEN_ARGS before appending the according computed values (if there is no such computed value because we are outside of a project then don't strip it).
