我的项目中有2个测试类，我想通过jenkins运行，每个测试类都有一个特定的配置文件（因为它们有不同的依赖项集）。我尝试创建一个参数“Class_To-Run”，它将具有要在前置步骤中运行的类的名称，然后执行项目为：
mvn clean compile test -Dtest=$Class_To_Run -P profileUsed
会抛出以下错误：
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.21.0:test (default-test) on project SparkTest: No tests were executed! (Set -DfailIfNoTests=false to ignore this error.)
However, if a specify the name of the class to be run in the command itself (-Dtest=ClassName), the project runs successfully. Am I committing some mistake? How do I make it parameterised?
以下是构建失败后的日志：

最后，我想通了。正如我在上面的评论中所说，当jenkins执行maven命令时，变量（“Class_To_Run”）没有被扩展到它的值。问题是我在jenkins作业配置的Pre Steps中的execute shell部分声明了变量。您在jenkins作业的常规步骤中创建的参数只能在构建步骤中访问。
