我已经安装了Eclipse IDE for J2EE，现在我正在尝试安装WTP。 我已经尝试了我能找到的所有解决方案，其他地方......
没有代理问题，因为我可以通过内部Web浏览器打开存储库网站。
我尝试将“-Djava.net.preferIPv4Stack = true”添加到eclipse.ini。
我已经尝试清除缓存，一个不同的工作区...... 顺便说一句，我是一个完整的新手。以防万一我错过了一些明显的东西。
无法连接到存储库http://download.eclipse.org/releases/helios/content.xml， 是我得到的错误！
如果有任何帮助，这里是该错误的堆栈：

显然，该存储库已弃用。您可能想尝试与新版本的eclipse相关联的仓库，例如朱诺。
尝试将其用作使用：
