尝试在Maven项目中运行Java文件时遇到障碍。我在运行Java类的地方进行了设置，然后使用run exec在Maven中运行其余测试。我可以在IDE工具（Eclipse）中很好地运行程序，但是当我从CMD或Git Bash运行程序时，我不断收到错误消息，指出找不到ClassDef或包/导入不存在（即使它在IDE中可以正常工作）并在Mvn命令上测试类。我尝试使用Javac-cp来查看新设置是否可以消除错误，但我也遇到类似的错误。我一直在寻找几个不同的答案，他们要么不能解决问题或使我的项目处于更糟糕的状态。现在，我不确定问题的确切原因是什么，并不确定要解决此问题的最佳解决方案。
这是我的问题的一个示例，我尝试编译连接到要运行的Java文件的Java文件之一，该文件将运行Maven：

AppiumDriverSetUp_Lib软件包中的XMLMaker文件：

这是我尝试编译Java文件以开始测试时的问题：
$ javac -d build/classes -sourcepath src -cp target/classes src/BaseTest/DriverTest.java

BaseTest软件包中的DriverTest：

public AppiumDriverSetup createDrivers = new AppiumDriverSetup();
public XMLMaker makeFile = new XMLMaker();

}
public void runSuite() throws IOException, InterruptedException {

Process p = rt.exec(cmd);
InputStream input = p.getInputStream();

p.waitFor();
}
public void testFeed(InputStream in, OutputStream out) throws IOException {
while (true) {
int c = in.read();
if (c == -1) {
break;
}
out.write((char)c);
}
}
}
在我的XMLMaker类中，它已经具有AppiumDriver和MobileElement的正确导入，作为IDE中正确的导入选项之一。如果我用mvn运行它也没问题。我认为问题与该项目的依赖关系有关。有人遇到过这样的情况吗？
答案 0 :(得分：1)
听起来，您在命令行中所做的任何事情都没有完全包括构建它所需的类。在Eclipse中，您可能会引用必要的JAR文件。
我的建议-如果您正在使用Maven实现构建自动化（应该这样做），则应完全使用它，其中构建过程将自动为您完成所有这些工作。
在您的情况下，我想只是确保javac知道在哪里可以找到XMLMaker的jar文件，并且可以找到必要的依赖项。
