我试图使用Maven (m2eclipse)建立一个项目,但我在Eclipse中得到这个错误:

Description Resource Path Location Type Could not calculate build plan: Failure to transfer org.apache.maven.plugins:maven-compiler-plugin:pom:2.0.2 from http://repo1.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven.plugins:maven-compiler-plugin:pom:2.0.2 from/to central (http://repo1.maven.org/maven2): No response received after 60000 ExampleProject Unknown Maven Problem

什么好主意吗? 如果你能告诉我如何检查是否一切配置正常,那就太有帮助了。


当前回答

这在Windows中也适用。

Locate the {user}/.m2/repository (Using Juno /Win7 here) In the Search field in upper right of window, type ".lastupdated". Windows will look through all subfolders for these files in the directory. (I did not look through cache.) Remove them by Right-click > Delete (I kept all of the lastupdated.properties). Then go back into Eclipse, Right-click on the project and select Maven > Update Project. I selected to "Force Update of Snapshots/Releases". Click Ok and the dependencies finally resolved correctly.

其他回答

谢谢你的回复,但经过更多的搜索,我能够解决这个问题。结果我不得不删除其中一个“*”。lastUpdated”,这是阻止我的一个插件(Maven Surefire插件)更新。我是手动清理的,因为清洁专家显然不会这么做。

问题是“*”。一个插件的lastUpdated文件阻止了maven检查更新,并且不允许下载必要的jar文件。

如果你是一个代理,你必须更新settings.xml文件(在你的MAVEN_HOME的conf文件夹下,文件本身包含关于代理设置的信息),另外你可能需要更新你的Eclipse网络设置(窗口->Preferences…)—>类型Network Connections)。

尝试使用-X或——debug来获得调试输出,这可以提供关于问题的额外信息。

您可以删除.m2文件夹本身,并强制MyEclipse在启动时重新下载所有依赖项。进入Window > Preferences > MyEclipse > Maven4MyEclipse。

这件事也发生在我身上,对此你可能有两种解决办法

If your project consist of some external or project specificdependency in it then you have to manually add it to your M2 repo folder which is located at C:\Users\Mohit.Singh.m2\repository folder and then you have to run mvn eclipse:eclipse and then mvn clean install from the project folder if you do not have any wxternal or project sppecific dependency then you may import the project into eclipse as Existing maven project then right click on project --> GO to maven --> Click on update project a window will appear check the force snapshot download option and hit on OK

我的工作空间里只有几个项目也有类似的问题。其他具有几乎相同pom的项目根本没有错误。列出的其他答案都不能解决我的问题。我最终无意中为每个项目删除/重新应用Maven特性,错误消失了:

对于每个项目,有一个pom与“决议将不会被重新尝试…”错误:

在Eclipse中右键单击项目并选择Maven->Disable Maven Nature 右键单击Eclipse中的项目并选择Configure->Convert to Maven project
