今天，当尝试使用 Eclipse Marketplace 在 Eclipse 上为 JEE 开发人员安装 WDT 时，我们得到：
An error occurred while collecting items to be installed

我尝试在 eclipse.ini 中设置超时但没有成功。

然后我尝试从http://public.dhe.ibm.com/ibmdl/export/pub/software/websphere/wasdev/updates/wdt/下载 jar com.ibm.websphere.v85.core_1.0.200.v20170227_1658.jar mars_comp/repository/plugins/卡在 3.0/44.0 MB
