m2eclipse 说“缺少工件"；但我可以从 cmdline 构建！ [英] m2eclipse says "Missing artifact" but I can build from cmdline!

问题描述

我第一次尝试使用这个 Sonatype Eclipse 插件来处理一个现有的(巨大的)软件，我可以使用 maven 从命令行构建它.

I'm trying to use this Sonatype Eclipse plugin for the first time to handle an existing (huge) software that I can build with maven form the command line.

我已将插件配置为使用我的 maven 2.2.1 安装而不是内置的 Maven 3.

I have configured the plugin to use my maven 2.2.1 installation instead of the built-in Maven 3.

在 Eclipse 中，我有 25 个项目(通过根 pom.xml 加载)，其中 4 个有编译错误；maven 控制台包含很多这样的行:

In Eclipse I have 25 projects (loaded through the root pom.xml) and 4 of them have compilation errors; the maven console contains a lot of lines like this one:

缺少工件 commons-logging:commons-logging:jar:1.0.4:compile

Missing artifact commons-logging:commons-logging:jar:1.0.4:compile

我的存储库中有所有 jar，并且正确定义了 M2_REPO 类路径变量.为什么插件看不到所有的罐子?

I have all the jars in my repository and the M2_REPO classpath variable correctly defined. Why the plugin doesn't see all the jars?

这些项目的 .classpath 文件仅引用MAVEN2_CLASSPATH_CONTAINER"，没有 jar 列表.Eclipse 中的 pom.xml 在第一行显示缺少 jar 的错误，但我可以从命令行构建！

The .classpath file of those projects simply references "MAVEN2_CLASSPATH_CONTAINER", there isn't a list of the jars. The pom.xml in Eclipse shows an error on the first line for the missing jars but I can build from the command line!

有什么想法吗?我需要帮助！如果我不解决这个问题，我会尝试迁移到 NetBeans.

Any idea? I need help! I will try to move to NetBeans if I don't solve this problem.

谢谢.

推荐答案

我终于找到了解决方法.这肯定是 m2eclipse 中的一个错误，但是当我在 中的 quartz-1.6.0.jar 旁边添加 quartz-1.6.0.pom 时，问题就消失了.m2 epositoryopensymphonyquartz1.6.0
pom 不存在于 http://repo1.maven.org/maven2/opensymphony/quartz/1.6.0/ 但您可以从 http://jira.opensymphony.com/browse/QUARTZ-482
这是一个奇怪的解决方案，但它也适用于我同事的 PC.

I finally found a workaround. It is surely a bug in m2eclipse, however the problem disappeared when I added quartz-1.6.0.pom next to quartz-1.6.0.jar in .m2 epositoryopensymphonyquartz1.6.0
The pom is not present at http://repo1.maven.org/maven2/opensymphony/quartz/1.6.0/ but you can extract it from quartz-1.6.0-bundle.jar linket at http://jira.opensymphony.com/browse/QUARTZ-482
It's a strange solution but it worked on the PCs of my collegues too.
