尝试使用 org.codehaus.mojo:cobertura-maven-plugin:2.6 时出错

Question

我正在尝试使用 Cobertura maven 插件进行代码覆盖。 但是在运行以下命令时出现错误：

mvn clean package cobertura:cobertura -Dcobertura.report.format=xml

这是我在 pom.xml 中定义插件的方式：

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>cobertura-maven-plugin</artifactId>
  <version>2.6</version>
  <configuration>
    <formats>
      <format>xml</format>
    </formats>
    <instrumentation>
      <excludes>
        <include>**/*.class</include>
        <exclude>**/*Test.class</exclude>
        <exclude>**/Test*.class</exclude>
      </excludes>
    </instrumentation>
  </configuration>
</plugin>

这是我收到的错误：

我已经清除了我的本地存储库并尝试再次运行它，但没有运气。

还有其他建议吗？

我正在使用 Maven 3.1.0 和 Java 1.7.0_45

更新：我使用 Nexus 作为回购经理。 查看日志我看到：

[INFO] Failed to parse Maven artifact /data/home/user/sonatype-work/nexus/storage/central/net/sourceforge/cobertura/cobertura/2.0.3/cobertura-2.0.3.jar due to invalid CEN header (bad signature)

这似乎表明这个 jar 已损坏。 但我一直试图从 Maven Central 重新下载它。 还是卡住了。

Answer 1

我也遇到了这个问题，问题出在 Maven 中的 Java 版本上。 您可能会在系统中有多个 JDK 版本，或者您的 Maven 引用其他一些 JDK 版本。

因此，首先您可以通过在 Maven 项目目录中键入以下命令来检查 Maven 和引用版本。

mvn -v

ITSs-MacBook-Pro:workbench vshah$ mvn -v Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f) Maven 主页：/usr/local/Cellar/maven/3.6.3_1/libexec Java 版本：241，Oracle 公司，运行时：241。 ：/Library/Java/JavaVirtualMachines/jdk1.8.0_241.jdk/Contents/Home/jre 默认语言环境：en_GB，平台编码：UTF-8 操作系统名称：“mac os x”，版本：“10.14.3”，arch： “x86_64”，家族：“mac”

并检查maven和JDK版本。 如果您发现 maven 的 JDK 版本未引用所需的 JDK 版本，那么您需要检查您的 JAVA_HOME 路径。 如果您正确设置了 JAVA_HOME 路径，它肯定会起作用。

Answer 2

用这个：-

<plugin>
   <groupId>org.codehaus.mojo</groupId>
   <artifactId>cobertura-maven-plugin</artifactId>
   <version>2.7</version>
   <configuration>
       <formats>
           <format>html</format>
           <format>xml</format>
       </formats>
       <reportSets>
           <reportSet>
               <reports>
                   <report>cobertura</report>
               </reports>
           </reportSet>
       </reportSets>
   </configuration>     
</plugin>

Answer 3

请检查您的路径变量。 您可能将它指向 jre bin 路径，它应该指向 jdk bin。 我遇到了同样的问题，我做了上述对我有用的解决方案。

Answer 4

尝试从外部站点下载并将其放置在您的本地存储库中。

Answer 5

如果你们正在使用 jenkins 并在执行描述性作业时遇到问题，那么还要检查配置，

如果您在“全局工具配置”中为 maven 和 Java 选择了自动安装选项，则取消单击它并手动添加您的 maven 和 java 安装在 jenkins 服务器上的目录。

Answer 6

最重要的一行是A required class was missing while executing org.codehaus.mojo:cobertura-maven-plugin:2.6:instrument: net/sourceforge/cobertura/util/CommandLineBuilder is A required class was missing while executing org.codehaus.mojo:cobertura-maven-plugin:2.6:instrument: net/sourceforge/cobertura/util/CommandLineBuilder 。 验证包含此类的 jar（即文件：/data/home/user/.m2/repository/net/sourceforge/cobertura/cobertura/2.0.3/cobertura-2.0.3.jar）是否已损坏。 是这样，从您的本地存储库中删除它。 如果您也在使用存储库管理器，请验证它是否也已损坏并需要删除。 接下来再试一次。
