我正在尝试在Eclipse Luna中安装一个插件.我安装了Papyrus,我正在尝试安装SWT设计器,但在下载/安装完成之前,我收到一个错误:

An error occurred during the
org.eclipse.equinox.internal.p2.engine.phases.CheckTrust phase.
session context was:(profile=epp.package.standard,
phase=org.eclipse.equinox.internal.p2.engine.phases.CheckTrust,
operand=, action=). Error reading signed content. error in opening zip
file

Run Code Online (Sandbox Code Playgroud)

在此错误之后,我无法安装任何东西,安装管理器不再工作,并且始终只向我显示相同的错误,删除当前Eclipse目录并再次提取它.

这次我安装了Papyrus,SWT设计师和其他一些,但我再次安装另一个插件之间的错误.如果我在安装任何插件时再次重新安装Eclipse和另一个插件时出错,那就错了.

这是一个错误还是一个问题？

大家好,这是我的第一个问题所以我为任何错过的期望道歉.

我需要Eclipse为我的计算机科学课安装用于Java编程的IDE,我已经尝试了两天但没有成功.我尝试了64位和32位安装,我得到完全相同的错误.这是非常令人沮丧的,因为每当我搜索所有人谈论的都是"插件".

这是我在安装时遇到的错误:
