Eclipse p2導演應用程序無法更新功能

我正在通過使用Eclipse built-in p2 director application開發Node.js script to install Eclipse plugins。在某些情況下，p2-director無法更新功能。Eclipse p2導演應用程序無法更新功能

我也試過路過都.feature.jar和feature.group。

eclipsec -nosplash -application org.eclipse.equinox.p2.director -repository jar:file:/D:/Workspaces/Nodeclipse-DEV/nodeclipse-1/org.nodeclipse.site/target/org.nodeclipse.site-0.10.0-SNAPSHOT.zip!/ -installIU org.nodeclipse.enide.maven.feature.feature.group -tag org.nodeclipse.enide.maven.feature.feature.group -vmargs -Declipse.p2.mirrors=false

這可能與以下事實：.maven功能包括.maven和.common插件。其他功能也使用插件.common。
但是，這種情況也會發生在沒有共享依賴關係的其他功能上。 p2導演幫助頁面沒有指定邏輯，也沒有提供參考。

在p2導演級別上，沒有「更新」操作。相反，你需要告訴導演都「卸載」和「安裝」的IU要進行更新：

eclipse -application org.eclipse.equinox.p2.director -uninstallIU org.nodeclipse.enide.maven.feature.feature.group -installIU org.nodeclipse.enide.maven.feature.feature.group -repository ...

不知插件設置將被保留，如果這將是原子操作，也就是說，如果安裝失敗，則不應應用卸載... –

p2具有提交/回滾邏輯，因此操作應該是原子操作。 – oberlies

您可以使用'IProvisioningAgent'和'org.eclipse.equinox.p2.operations.UpdateOperation'來更新p2功能（在任何配置文件中），但它不作爲命令行工具公開。 –
