无法解决 Maven 依赖项答案

【问题标题】：Maven Dependencies can't be resolved无法解决 Maven 依赖项
【发布时间】：2012-01-12 12:58:03
【问题描述】：

我正在使用 Apache Maven3，两三天后，一些依赖项无法再解决，这首先没有问题。更具体地说：

maven-findbgs-plugin:plugin:1.3.1
maven-cobertura-plugin:plugin:1.3

它们不应该被 maven 本身包含吗？

我的pom.xml 文件：

在我的 IDE（Springsource 工具套件）中，我收到以下警告

当我在 shell 中执行“mvn compile”之类的操作时，会出现以下错误：

非常感谢任何帮助。

【问题讨论】：

嗯，不，没有任何东西是自动包含的。发布您的 pom.xml 可能会有用。执行哪个操作时，您究竟会遇到什么错误？
@yair 我已经更新了我的描述。希望现在已经足够了......
Maven failure to find maven-plugins:maven-cobertura-plugin 的可能重复项

标签： maven-plugin maven-3

【解决方案1】：

你应该将这两个插件添加到你的 pom 中。

对于 cobertura，请参阅this page。

有关查找错误，请参阅this page。

----- 已更新 -----

好的，我发现了问题。看来您依赖于 jdom 1.1.2，它依赖于 jaxen 1.1.3，其中的工件已损坏。

您可以尝试另一个 jdom 版本，也可以将this site 中描述的快照添加到您的 pom 中。当我在我的电脑上运行你的 pom 时为我工作。我复制了快照：

<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>

【讨论】：

我已将它们包括在内，但没有成功。我已经用错误消息更新了上面的描述。

【解决方案2】：

对于那些试图用 Ivy 修复它的人。这个对我有用：

<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>

【讨论】：

【解决方案3】：

查看您的本地存储库 (normaly in <home>/.m2)，工件应该在哪里。你会在那里找到<artifactname>.lastUpdated 文件。删除这些，然后重试。

可能由于网络问题而无法加载工件，现在甚至没有检查。

【讨论】：

不幸的是，这并不成功。我删除了文件并更新了 IDE 中的项目配置。文件已再次创建，但错误消息仍然存在。还有其他想法吗？
当您通过浏览器中的 maven 正在访问的 URL 时会得到什么？

【解决方案4】：

您可以使用 Eclipse 中的 POM 编辑器查看依赖关系图。它很快向我展示了 jaxen-1.1.3 包含旧的 maven1 依赖项。 Eclipse 甚至提供当场排除它们。不错。
