Following the wiki for a NetBeans installation at http://ojwiki.soldin.de/index.php?title=How_to_run_OpenJUMP_in_NetBeans, I have NetBeans IDE 8.0 and followed the instructions only to be blocked. Here's what I did:
NetBeans Main Menu->Team->Subversion->Checkout...
[See attached screenshot of dialog]
Clicked "Next"
Got dialog window:
Title: SVN Command Failed
SVN command returned with the following error:
org.apache.subversion.javahl.clientexception: svn: e175002: invalid argument: connect
svn: e175002: options request failed on '/p/jump-pilot/code'
Thereafter, there is an error message in the Subversion Checkout Dialog:
[error icon] No information available for: http://svn.code.sf.net/p/jump-pilot/code
[See attached screenshot of dialog]
I was able to get the project imported inot NetBeans 8. (I had to create a JAVA variable JAVA_TOOL_OPTIONS=-Djava.net.preferIPv4Stack=true
to overcome a problem I have experienced with Java and Windows7 and IPV6.)
So now I'm able to build the project and start tinkering with the " resolution of the decimator" referenced in Java2DConverter.
