出現錯誤注入錯誤：org.jacoco.maven.AgentMojo 而 maven 構建

Question

我正在嘗試構建一個 maven 項目，但它給了我以下錯誤。

java.lang.NoClassDefFoundError: org/jacoco/core/runtime/AgentOptions

即使我在 maven repo 中有 jacoco-maven-plugin:0.7.9 和 org.jacoco.core-0.7.9 ，它也會給出這個錯誤。

我正在使用 mvn clean install 命令來構建應用程序。 此外，我還嘗試使用 -U 標志進行構建

最后，當我使用 -X 選項構建它時，我看到下面的堆棧跟蹤

Answer 1

您可以使用參數-X運行 maven 構建命令以啟用調試日志記錄。 使用此 output 您現在可以在日志中看到以下行：

[WARNING] The POM for org.jacoco:jacoco-maven-plugin:jar:0.7.9 is missing, no dependency information available

通常 class AgentOptions從org.jacoco.core加載，這是插件的依賴項。 但是沒有 pom 文件，maven 構建過程不知道這一點，即使您的本地存儲庫中有 jar 文件，由於缺少 pom 文件，它也不會被使用。

在我的本地 m2 中，我確實有以下 pom 文件： .m2\repository\org\jacoco\jacoco-maven-plugin\0.7.9\jacoco-maven-plugin-0.7.9.pom 。 這使我相信您下載的副本有問題。

我已經通過刪除插件 pom 文件的本地副本中的dependencies項列表來驗證這會導致問題，然后我在構建過程中收到相同的錯誤消息。

作為一種解決方案，您可以清除.m2\repository\org\jacoco\的內容並再次嘗試構建，然后應從 maven 中心再次下載所有正確的插件文件和依賴項。

我們還可以看到[DEBUG] Skipped remote request for org.jacoco:jacoco-maven-plugin:pom:0.7.9, already updated during this session. ，這可能表明下載 pom 文件時出現問題。 .m2\repository\org\jacoco\jacoco-maven-plugin\0.7.9\_remote.repositories中是否有任何錯誤？

是嘗試從central下載，還是您有任何可能沒有完整 pom 文件的自定義pluginRepositories ？ 您可以通過運行mvn help:effective-pom查看整個 pom 文件。

通常這應該包括來自super pom的以下內容：

  <pluginRepositories>
    <pluginRepository>
      <releases>
        <updatePolicy>never</updatePolicy>
      </releases>
      <snapshots>
        <enabled>false</enabled>
      </snapshots>
      <id>central</id>
      <name>Central Repository</name>
      <url>https://repo.maven.apache.org/maven2</url>
    </pluginRepository>
  </pluginRepositories>

更極端的措施可能是下載更新版本的 maven，或清除整個本地.m2 （如果您有重要文件，請創建備份）。

這些將是尋求解決此問題的地方。
