我有一个项目，它只包含所有从一个抽象基类扩展的测试类。测试在 intellij 中运行良好，并且在使用指定的正确配置文件运行 mvn clean install 时。
我想要做的是创建一个测试 jar 并从命令行运行测试，所以我使用这些命令：
mvn -DoutputDirectory=target -f pom.xml dependency:copy-dependencies
第一个命令是获取所有依赖项并将它们放在目标文件夹中创建的测试 jar 旁边。
java -cp .;target/* org.testng.TestNG -testjar target/my-test-jar.jar -xmlpathinjar sanity.xml
我明白了：
[TestNG] [ERROR]
Cannot instantiate class com.myPackage.MyTestClass
该类肯定存在，我可以从 intellij 内部运行 sanity.xml。
最奇怪的是我可以从我的项目中删除java文件，然后把这个：
public static void main(String[] args){
args = new String[4]
args[0] = "-testjar"
args[1] = "target/my-test-jar.jar"
args[2] = "-xmlpathinjar"
args[3] = "sanity.xml"
org.testng.TestNG.main(args)
}
在我项目的另一个测试类中，它将设法从 jar 文件中实例化 MyTestClass。
有人对此有任何想法吗？我没有得到任何堆栈跟踪或日志文件，只是它无法实例化类的简单事实。我希望有人以前遇到过这个问题并且知道如何解决它。
干杯，大卫
