我已经在我的 pom.xml 文件中配置了 Maven JaCoCo 插件:

我正在使用 Windows 7 和 apache-maven-3.0.4 插件。当我从 cygwin 终端或命令提示符终端键入 mvn -P jacoco4 install 时，Maven 下载并运行 JaCoCo 插件，然后是 jacoco.exec 文件似乎没有被创建。以下是错误信息:

无论我是否在插件配置中包含 destfile 和 datafile 说明符，都会出现此错误消息:

<destfile>${project.build.directory}/target/jacoco.exec</destfile>
<datafile>${project.build.directory}/target/jacoco.exec</datafile>

有人可以告诉我我做错了什么吗？

最佳答案

我在使用 jacoco 和 maven 时遇到了同样的问题。 它与父 pom 覆盖 surefire 的配置有关。 在这种情况下，该插件没有使用定义代理的参数(对于 jvm 参数)。

解决方案是将“argLine”配置元素放回去

<plugin>
  <artifactId>maven-surefire-plugin</artifactId>
  <configuration>
   <argLine>${argLine}</argLine>
  </configuration>
 </plugin>

完整的插件配置看起来像

<plugin>
  <artifactId>maven-surefire-plugin</artifactId>
  <configuration>
    <skip>true</skip>
  </configuration>
  <executions>
    <execution>
      <id>unit-test</id>
      <phase>test</phase>
      <goals>
        <goal>test</goal>
      </goals>
      <configuration>
        <skip>${maven.test.skip}</skip>
        <argLine>${argLine}</argLine>
        <excludes>
          <exclude>**/*IntegrationTest.java</exclude>
        </excludes>
      </configuration>
    </execution>
    <execution>
      <id>integration-test</id>
      <phase>integration-test</phase>
      <goals>
