configuration - Netbean 6.9.1 library problem -

i have upgraded netbeans 6.9.1 netbeans 6.8 , next problem arose not there in netbeans 6.8:

i have own project jar (let's name alma.jar) used in several other project. beans alma.jar appears on palette. alma.jar in dist folder of alma project , other projects see it/use it. since alma continuously developed added add together project.. when other project cleaned , rebuilt alma.jar rebuilt. netbeans 6.9.1 clean not working netbeans 6.9.1 locks alma.jar, cannot deleted filesystem (i using windows xp). when first delete alma.jar , after start netbeans 6.9.1 warnings during startup when form open using alma.jar's classes appearing on palette otherwise can clean , build correctly.

how avoid deletion of alma.jar before netbeans startup?

this not solution workaround:

if turn on 'compile on save' setting of project, can avoid of clean , build processes.

configuration netbeans netbeans-6.9
