Eclipse软件安装插件报错

今天打开Eclipse软件发现以前安装的Darkest Dark Theme with DevStyle
CI 2019.4.1插件失效，于是重新下载，但是安装到49%中出现如下错误:
An error occurred while collecting items to be installed

经过一番折腾，我总结为两点，一方面可能是网络的原因(毕竟是校园网)，另一方面可以通过以下步骤解决:点击Install New SoftWare→在Work With后面输入以下地址http://download.eclipse.org/eclipse/updates/4.4，Name自己随便起，
找到Eclipse Tests, Examples, and Extras下的 Eclipse 2.0 Style Plugin Support勾选并安装，最后重新安装该插件问题解决!此方法参考http://code.google.com/p/veloeclipse/issues/detail?id=47
