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

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。

其他回答

由于删除了'maven-compiler-plugin 2.0.2'而出现上述错误 来自maven存储库。 对我来说,当我将'maven-compiler-plugin'降级到2.0或2.0.1版本时,上述错误得到了解决。

创建一个文件delete_lastUpdated_and_remote.sh(使用\n):

#!/bin/bash
find $(cd $(dirname $0); pwd) -name "*.lastUpdated" -type f -print -exec rm -rf {} \;
find $(cd $(dirname $0); pwd) -name "_remote.repositories" -type f -print -exec rm -rf {} \;

把它放在本地Maven repo中,例如%userprofile%\。M2 \repository或~/。M2 /repository,并运行它。

在windows中,你也应该安装Git来运行sh文件。

我也用在jenkins的工作上。

只需删除maven本地存储库中的原型。如上所述,它发生在原型下载失败的情况下。

对于mac

我删除了所有旧的maven失败的下载,在我的mac上也有几个版本的maven

寻找~ /。M2 -name "*。lastUpdated" -exec grep -q " cannot transfer" {};-print -exec rm {};

之后,我简单地更新了我的eclipse

帮助->检查更新

这个问题为我解决了

这个问题的主要原因是失败的旧更新不允许你下载原型,所以如果你试图在maven的任何原型中构建项目,它会失败

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.
