Eclipse p2 Director应用程序无法更新功能 [英] Eclipse p2 director application cannot update a feature

问题描述

我正在开发 Node.js脚本来安装Eclipse插件，方法是使用 Eclipse内置的p2 Director应用程序。而且p2-director在某些情况下无法更新功能。

I am developing Node.js script to install Eclipse plugins by using Eclipse built-in p2 director application. And p2-director fails to update features in some cases.

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

我也尝试同时传递两个 .feature.jar 和 feature.group 。

I also tried passing both .feature.jar and 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。 .common 插件也被其他功能使用。

但是，其他功能也存在这种情况，这些功能没有共享的依赖关系。 p2 Director帮助页面没有指定逻辑，也没有给出引用。

This maybe related to the fact that .maven feature includes .maven and .common plugins. .common plugin is also used by other features.
However this also happens with other features, that have no shared dependencies. p2 director help page does not specify the logic nor gives references.

推荐答案

在p2 Director级别上，没有更新操作。相反，您需要告诉控制器卸载和安装要更新的IU：

On the p2 director level, there is no 'update' operation. Instead, you need to tell the director to both 'uninstall' and 'install' the IU that you want to be updated:

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