import eclipse project with JDK/JRE 1.3- to netbeans, after import try build this project and message javac: invalid flag: -source Usage: javac <options> <source files> appears. Changing java platform to 1.4 and back to 1.3 solves this problem and project finaly behaves as true NB project. ----- I've reported this problem to projects earlier and they fixed it for common NB projects created with JDK 1.3 and lower. I guess you have generated wrong project.xml see http://www.netbeans.org/issues/show_bug.cgi?id=55608 comments from tzezula :-)
Obsolete milestone, please reevaluate
No plans to fix this this.
