Spring Tool Suite：错误更新至3.9.0版本

Question

我正在从版本：3.8.4.RELEASE更新Spring Tool Suite到版本3.9.0 Build ID：201703310825平台：Eclipse Neon.3（4.6.3）

但我已经此错误：

An error occurred while collecting items to be installed

No repository found containing: osgi.bundle,com.vmware.vfabric.ide.eclipse.tcserver.core,3.9.0.201707061818-RELEASE

...

请，任何帮助吗？

Answer 1

这看起来很像p2使用一些陈旧或损坏的缓存数据。要解决此问题，您可以转到Preferences -> Install/Update -> Available Udpate Sites并在STS更新站点上按Reload。

如果这没有帮助，您还可以尝试删除该更新站点，重新启动STS，并将该更新站点添加回列表中。这会导致内部缓存被清除。

希望这会有所帮助！

今天STS没有找到任何更新！很奇怪...

这是我的可用更新站点列表。

我试过重新载入每个站点，但没有任何反应。

但是，也许我没有在STS更新列表中的网站？
