我正在尝试在 Eclipse 4.2 中安装 perforce 插件。在官方网页上，只有 4.6 及更高版本的可下载版本。但是，在安装过程中尝试使用最旧的 4.6 版本失败，输出如下
Cannot complete the install because one or more required items could not be found.
Software being installed: Perforce SCM Support 2017.1.1583678 (com.perforce.team.feature.feature.group 2017.1.1583678)
Missing requirement: Perforce Team Provider UI 2017.1.1583678 (com.perforce.team.ui 2017.1.1583678) requires 'bundle com.google.gson 2.2.4' but it could not be found
Cannot satisfy dependency:
From: Perforce SCM Support 2017.1.1583678 (com.perforce.team.feature.feature.group 2017.1.1583678)
To: com.perforce.team.ui [2017.1.1583678]
由于我使用 IBM 的 Integration Bus 10.0.0.13 Toolkit，我无法将 Eclipse 升级到更新的版本。此处提供的旧解决方案不再起作用：How to install the Perforce plugin in Eclipse 3.8 because the download link is dead.
我尝试下载这个 jar 文件http://repo1.maven.org/maven2/com/google/code/gson/gson/2.2.4/gson-2.2.4.jar但找不到显示如何让 Eclipse 使用它。
有没有人有同样的问题？
