Maven：无法解析依赖关系：C：\Program Files\Java\lib\tools.jar [英] Maven: Failed to resolve dependency: C:\Program Files\Java\lib\tools.jar

问题描述

我正在尝试使用货物插件从Eclipse内部的本地Jetty容器中运行Web应用程序。这似乎适用于具有完全相同的pom.xml的其他人，但是我收到以下错误：

I'm trying to use the cargo plugin to run a web application in a local Jetty container from inside Eclipse. This seems to be working for other people with the exact same pom.xml, but I get this error:

[ERROR] Failed to execute goal org.codehaus.cargo:cargo-maven2-plugin:1.0.3:start (default-cli) on project wsc: Failed to resolve dependency: C:\Program Files\Java\lib\tools.jar -> [Help 1]

我该如何解决？该项目设置为使用jdk1.7.0作为JRE系统库。我使用-vm启动Eclipse，甚至将JAVA_HOME设置为JDK路径。

How do I resolve this? The project is set to use jdk1.7.0 as the "JRE System Library". I am starting Eclipse with "-vm " and even JAVA_HOME is set to the JDK path.

任何想法？我一直在研究一段时间，并对此感到疯狂。 将tools.jar作为依赖关系的文档没有帮助我。

Any ideas? I've been researching on this for a while and getting crazy about that. The documentation on including tools.jar as dependency didn't help me.

重要提示：这似乎在Eclipse之外工作，例如与 mvn -P本地货物：开始。

Important: This seems to work outside Eclipse, e.g. with mvn -P local cargo:start.

程序输出从Eclipse开始时：

推荐答案

你必须用jdk启动eclipse而不是jre。
如果你编辑你的eclipse.ini并把一个jdk放在vm参数中，它应该可以工作。

You have to start eclipse with a jdk instead of a jre. If you edit your eclipse.ini and put a jdk to the vm arguments it should work.

-vm
