无法解析Maven依赖项。

I'm using Apache Maven3 and since two or three days some dependencies can't be resolved any more, which first have not had a problem. To be more specific its:

我使用的是Apache Maven3，两三天以后，一些依赖关系就不能再解决了，这是第一个没有问题的问题。更具体地说:

1. maven-findbgs-plugin:plugin:1.3.1
2. maven-findbgs-plugin:插件:1.3.1
3. maven-cobertura-plugin:plugin:1.3
4. maven-cobertura-plugin:插件:1.3

Shouldn't they be included by maven itself?

它们不应该被maven所包含吗?

My pom.xml file:

我砰的一声。xml文件:

You should add those two plugins to your pom.

您应该将这两个插件添加到您的pom中。

For cobertura, see this page.

对于cobertura来说，请看这一页。

For findbugs, see this page.

对于findbugs，请参见此页。

OK, I found the problem. It appears that you depend on jdom 1.1.2, which depends on jaxen 1.1.3 of which artifact is broken.

好吧，我发现问题了。看起来您依赖于jdom 1.1.2，它依赖于jaxen 1.1.3的工件被破坏。

You can either try another jdom version or add to your pom the snapshot described in this site. Worked for me when I ran your pom on my PC. I copied the snapshot:

您可以尝试另一个jdom版本或添加到您的pom中描述的快照。当我在我的电脑上运行你的pom时为我工作。我复制快照:

<dependency>
  <groupId>jaxen</groupId>
  <artifactId>jaxen</artifactId>
  <version>1.1.3</version>
  <!-- http://jira.codehaus.org/browse/JAXEN-217 -->
  <exclusions>
    <exclusion>
      <groupId>maven-plugins</groupId>
      <artifactId>maven-cobertura-plugin</artifactId>
    </exclusion>
    <exclusion>
      <groupId>maven-plugins</groupId>
      <artifactId>maven-findbugs-plugin</artifactId>
    </exclusion>
  </exclusions>
</dependency>

#2

For those who try to fix it with Ivy. This one worked for me:

对于那些试图用常春藤来修复它的人。这个方法对我有效:

<dependency org="jaxen" name="jaxen" rev="1.1.4"/>
<dependency org="net.sourceforge.cobertura" name="cobertura" rev="1.9.4.1"/>
<dependency org="com.google.code.findbugs" name="findbugs" rev="2.0.1"/>
<dependency org="org.jdom" name="jdom" rev="2.0.2">
  <exclude module="jaxen"/>
  <exclude name="maven-cobertura-plugin"/>
  <exclude name="maven-findbugs-plugin"/>
</dependency>

#3

Look in your local repository (normaly in <home>/.m2), where the artifacts should be. You'll find <artifactname>.lastUpdated files there. delete those and try again.

查看本地存储库(在 /.m2)中，工件应该在哪里。你会发现< artifactname >。lastupdate文件。删除那些，再试一次。

Possibly the artifacts failed to load due to network problems and now aren't even checked.

可能由于网络问题，工件无法加载，现在甚至没有检查。

#4

You can use the POM editor in Eclipse to see the dependency graph. It quickly showed my that jaxen-1.1.3 includes old maven1 dependencies. Eclipse even offers excluding them on the spot. Nice.

您可以在Eclipse中使用POM编辑器查看依赖关系图。它很快显示了我的jaxen-1.1.3包含了老的maven1依赖项。Eclipse甚至提供排除它们的服务。好了。
