我有一个Jenkins作业，它使用Ant来构建一个项目。
该项目使用Java 7。Jenkins作业的运行时也是Java7。我使用的是运行在Java 8上的SonarQube 5.6。SonarQube服务器运行良好。
然而，当需要调用Ant中的<sonar:sonar />目标时，我会得到以下错误，这显然是由于Java版本不匹配（JVMCFRE003 bad major version）造成的。我不知道如何解决这个问题。

问题是，我们谈论的是Jenkins作业，该作业使用的Java版本将用于该作业中的每个步骤。由于您使用Java7运行作业，因此分析也使用Java7&与SonarQube 5.6+不兼容。
最简单的方法是将分析从Ant脚本转移到SonarQube Scanner构建步骤中；它将允许您从运行作业的版本中选择不同的Java版本。
或者，您可以使用管道来实现这一点
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]'
}
}
您的第三种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）
