我正在尝试运行 testng 并得到下面的异常。

private static String lastResult;
public void run(){
TestNG testNG = new TestNG();
Utils.init();
try {
XmlSuite suite = new XmlSuite();
suite.setName("TmpSuite");
XmlTest test = new XmlTest(suite);
test.setName("TmpTest");
List<XmlPackage> packages = new ArrayList<>();
packages.add(new XmlPackage(".*")); //this line throw exception
test.setXmlPackages(packages) ;
List<XmlSuite> suites = new ArrayList<>();
suites.add(suite);
testNG.setXmlSuites(suites);
} catch (Exception e) {
e.printStackTrace();
}
testNG.run();
// TODO: step 1: run ngtest

lastResult = "TODO: read report.html";
}
public String getResult(){

}

最佳答案
看来，问题是由依赖冲突引起的，即依赖 assertj-swing-testng 版本 2.1.1 依赖于 testng 版本 5.7，该版本不会自动被 Maven 识别为与版本 6.14.3 存在依赖冲突。
如果可能，我建议将 pom.xml 中的 assertj-swing-testng 版本更新为较新的版本，例如，您可以使用版本 3.8.0 :
<dependency>
<groupId>org.assertj</groupId>
<artifactId>assertj-swing-testng</artifactId>
<version>3.8.0</version>
</dependency>
另一种选择是排除嵌套的 testng 依赖项，但这仅对于较小的版本差异是安全的，因为任何版本不兼容都可能导致依赖项损坏。
如何定位此类问题。在Eclipse IDE中查看pom.xml时，有一个选项卡Dependency Hierarchy，其中显示嵌套依赖关系的 TreeView ，能够过滤它们。
关于java - 在没有 XML 的情况下以编程方式运行 testng 会抛出 NoSuchMethodError XmlPackage，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/49964185/
