我把这个jar包删了上面的错误没了，有个新的错误
新的错误是。。。
求解，这是怎么回事 jar --------------------编程问答-------------------- 无法找到osgi-default父包 --------------------编程问答-------------------- 一般error百度一下应该有答案 --------------------编程问答-------------------- jar包多的话，一般都是重复的，或者与其他冲突的，仔细检查一下吧，另外应大概了解一下各个jar包用处 --------------------编程问答-------------------- 无法找到osgi-default父包
补充：Java , Java EE
