Hi, I asked the following question on the osgi mailing list and was correctly reminded that this might be a better location since it's related to gogo.
I am trying to specify some required parameters in Gogo but I can't find a way to set absentValue to null (can't just not provide it as it is required). This won't compile: @Parameter(names="-ps") @Descriptor(PS_DESCR) String psName, Example: @Parameter(names="-ps", absentValue= "") @Descriptor(PS_DESCR) String psName, results in: -ps ProjectSpace name [optional] Where I want it not to show up as optional. The code <https://github.com/apache/felix-dev/blob/31aea2b06d5bd0e620f86b5874904a1616683873/gogo/jline/src/main/java/org/apache/felix/gogo/jline/Shell.java#L708> checks for null, otherwise it will add the "[optional]" tag. Full example: @Descriptor("...") public void createTenantAndUserOnKCBA( @Parameter(names={"-t", "--tenant"}, absentValue="") @Descriptor(TENANT_DESCR + REQ) String tenantName, @Parameter(names="-ps", absentValue= "") @Descriptor(PS_DESCR) String psName, @Parameter(names="-email", absentValue="") @Descriptor(EMAIL_DESCR + REQ) String email, @Parameter(names="-fname", absentValue="") @Descriptor(FNAME_DESCR + REQ) String firstName, @Parameter(names="-lname", absentValue="") @Descriptor(LNAME_DESCR + REQ) String lastName, @Parameter(names="-full", absentValue="") @Descriptor(FULL_NAME_DESCR) String fullName, @Parameter(names="-pwd", absentValue="") @Descriptor(PASS_DESCR + REQ) String password, @Parameter(names="-ent", absentValue="") @Descriptor(ENT_DESCR) String enterpriseName) { //perform command } Thanks Alain
