Maven 2-无法计算构建计划

Question

我在笔记本电脑上设置了Maven 2.我仍在使用Maven 2的原因是Maven,不知何故,因为我公司的代理而无法工作.

工作环境:Eclipse Helio Service Release 2 Maven 2.2.1 Windows 7

错误消息:

Errors occurred during the build.
Errors running builder 'Maven Project Builder' on project 'StrutsExample'.
Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.5 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.5
Plugin org.apache.maven.plugins:maven-resources-plugin:2.5 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.5

我以为它找不到2.5 jar所以我下载了它并将其手动添加到本地存储库中并使用相应的pom文件,但它仍然无法正常工作...

有什么建议吗？提前致谢...

Answer 1

我的工作方案:

• 关闭Eclipse
• 转到c:\Users\*yourUser*\.m2\repository目录
• 删除m2e-lastUpdated.properties所有子目录上名为present的所有文件
• 重启eclipse,刷新和更新Maven项目

我确切的错误是:

无法计算构建计划:插件org.apache.maven.plugins:maven-jar-plugin:2.4或其中一个依赖项无法解析:无法读取org.apache.maven.plugins的工件描述符:maven-jar-插件:罐子:2.4

引起:org.sonatype.aether.resolution.ArtifactResolutionException:无法转移org.apache.maven.plugins:maven-jar-plugin:pom:2.4来自http://repo.maven.apache.org/maven2的缓存在本地存储库中,在中心的更新间隔过去或强制更新之前,不会重新尝试解析.
