Hello Jan,
I think Basin is stating that if you invoke ant from the command line
and pass it an explicit target to invoke (instead of whatever default
target is configured for that project) and if you have a -D property
which doesn't specify a value, then the explicit target name that you
specified is ignored and instead Ant just runs the default target
configured for that project.
I haven't had a chance to try it out myself, but having seen similar
issues reported (outside of Ant) when -D with an empty property value is
used in Windows, I wouldn't be surprised if this is Windows specific.

Betreff: empty properties on command line
Hi list.
Looks like it's well-known, but I can't find in the docs.
Trying to pass a property with an empty value on the command line leads to
ignoring explicit targets:
C:\16>ant -Daaa= clean
Buildfile: C:\16\build.xml
default:
[echo] default
BUILD SUCCESSFUL
Total time: 0 seconds
C:\16>ant -Daaa=d clean
Buildfile: C:\16\build.xml
clean:
[echo] clean
BUILD SUCCESSFUL
Total time: 0 seconds
Even Eclipse mimics this behavior in
InternalAntRunner.processMinusDProperties()
I expected some info here: https://ant.apache.org/manual/running.html
