Eclipse p2指导器应用程序无法更新功能

Question

我正在使用安装的Node.js脚本开发Eclipse内置的p2指导应用程序。在某些情况下，p2-总监无法更新功能。

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

eclipsec process exit code 13

我还试着通过.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特性包括.maven和.common插件有关。.common插件也被其他特性所使用。

但是，这种情况也发生在没有共享依赖关系的其他特性上。p2主管帮助页不指定逻辑，也不提供引用。

在p2主管级别上，没有“更新”操作。相反，您需要告诉主管您想要更新的“卸载”和“安装”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 ...
