哪位仁兄能帮帮。。。小弟不胜感谢。

直接使用10.x的破解包，在终端输入
sudo java -jar cracker.jar
按程序里面的指示破解就可以了，跟Windows下一模一样的

1. 输入Usercode, 点击*SystemId...*, 生成SystemId
2. 点击*Active*, 生成LICENSE_KEY, ACTIVATION_CODE, ACTIVATION_KEY
3. 点击菜单*Tools -> 2.SaveProperties...*,
目的是把生成的LICENSE_KEY, ACTIVATION_CODE, ACTIVATION_KEY保存到~/myeclipse.properties文件中
4. 点击菜单*Tools -> 1.ReplaceJarFile*, 选择${eclipse_home}/plugins目录, 等待30秒左右.
目的是:
