buildpath - Change java build path for multiple projects in Eclipse -


in eclipse, have libs project. project has test.jar file.

i have 15 other projects in eclipse use test.jar under java build path/libraries.

new versions of test.jar made every month, , name change (test1.jar, test2.jar)

once new version available, remove old 1 libs project , add new one. question is, how can modify 15 projects use jar file reference new one? know how 1 project @ time configuring build path each project. there way make mass change 15 projects @ same time?

to achieve same follow below steps.

1) open eclipse go windows->preferences->java->build path->user library
2) click on new button , give name test_jar , add after add jar test.jar or test.jar. see below screen shot.

enter image description here

3) 1 time task delete entry 15 project build classpath set in global path.

4) whenever build other project bundle user libraries.
