Eclipse p2 Director应用程序无法更新功能

Question

我正在开发Node.js脚本，以使用Eclipse内置的p2 Director应用程序安装Eclipse插件。在某些情况下，p2-director无法更新功能。

D:\Workspaces\Nodeclipse-DEV\nodeclipse-1\org.nodeclipse.ui\templates>node nodeclipse-install.js install -repository jar:file:/D:/Workspaces/Nodeclipse-DEV/nodeclipse-1/org.nodeclipse.site/target/org.nodeclipse.site-0.10.0-SNAPSHOT.zip!/ maven

Cannot complete the install because of a conflicting dependency.

eclipsec process exit code 13

我还尝试通过.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

这可能与.maven功能包括.maven和.common插件有关。.common插件也被其他功能使用。
但是，其他没有共享依赖关系的功能也会发生这种情况。p2 Director帮助页面未指定逻辑，也未提供参考。

在p2导演级别上，没有“更新”操作。相反，您需要告诉导向器“卸载”和“安装”要更新的IU：

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