SonarQube 5.6.1 在使用 Ant 编译 Java 7 项目时抛出错误的主要版本

Question

我有一份使用 Ant 构建项目的 Jenkins 工作。

该项目使用 Java 7。Jenkins 作业的运行时也是 Java 7。我使用的是在 Java 8 上运行的 SonarQube 5.6.1。SonarQube 服务器运行良好。

但是，当需要在 Ant 中调用 <sonar:sonar /> 目标时，我收到以下错误，这显然是由于 Java 版本不匹配 (JVMCFRE003 bad major version)。我不知道如何解决这个问题。

Answer 1

问题是我们谈论的是 Jenkins 作业，而用于作业的 Java 版本将用于作业中的每个步骤。由于您使用 Java 7 运行作业，因此分析也使用 Java 7 运行，并且与 SonarQube 5.6+ 不兼容。

最简单的做法是将分析从 Ant 脚本转移到 SonarQube Scanner 构建步骤；它会让您选择与运行作业的 Java 版本不同的 Java 版本。

或者你也可以完成这个with a pipeline

node() {
  def jdk8 = tool 'jdk-8u45'
  def jdk7 = tool 'jdk-7u70'
  withEnv(["PATH+JDK7=${jdk7}/bin"]) {
    sh 'ant [normal target here]'
  }
  withEnv(["PATH+JDK8=${jdk8}/bin"]) {
    sh 'ant [analysis target here]'
  }
}

您的第三个选择是将作业拆分为 2 并使用共享工作区（配置 > 项目选项 > 高级 > 使用自定义工作区）
