maven Java或JavaC一直说包未找到或不存在
当我试图在Maven项目中运行Java文件时遇到了一个障碍。我在运行Java类的地方进行了设置，该类在使用RunExec运行Maven中的其余测试之前进行了一些设置。我可以在IDE工具（Eclipse）中很好地运行程序，但当我从CMD或Git Bash运行程序时，我不断收到错误，指出找不到ClassDef或包/导入不存在， （尽管它在IDE和Mvn命令中可以很好地测试类。我尝试使用Javac-cp。为了看看新设置是否能消除错误，但我也遇到了类似的错误。我四处寻找了几个不同的答案，它们要么不能解决问题，要么使我的项目处于更糟糕的状态。现在，我不确定确切的cau是什么。）解决问题并确定解决此问题的最佳解决方案
以下是我的问题示例，我尝试编译一个连接到我要运行的java文件的java文件，该文件将运行Maven：

当我试图编译Java文件以启动测试时，出现了以下问题：
$ javac -d build/classes -sourcepath src -cp target/classes src/BaseTest/DriverTest.java
src\BaseTest\DriverTest.java:29: error: cannot access AppiumDriver
makeFile.setupDriverXMLFile(createDrivers.getActiveList());
^
class file for io.appium.java_client.AppiumDriver not found

基本测试包中的DriverTest：
import AppiumDriverSetUp_Lib.AppiumDriverSetup;
import AppiumDriverSetUp_Lib.XMLMaker;
public class DriverTest {
public AppiumDriverSetup createDrivers = new AppiumDriverSetup();
public XMLMaker makeFile = new XMLMaker();
public static void main(String [] args) throws TransformerConfigurationException, IOException, InterruptedException {
System.out.println("Setting up drivers:");
DriverTest startTest = new DriverTest();
startTest.driverFileSetup();
startTest.runSuite();
}
public void driverFileSetup() throws IOException, TransformerConfigurationException, InterruptedException {
createDrivers.makeList();
makeFile.setupDriverXMLFile(createDrivers.getActiveList());
makeFile.createDriverFile();
}
public void runSuite() throws IOException, InterruptedException {
Runtime rt = Runtime.getRuntime();
String cmd = "cmd /c mvn test -Dplat="+System.getProperty("plat");
Process p = rt.exec(cmd);
InputStream input = p.getInputStream();
testFeed(input, System.out);
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，它已经为AppiumDriver和MobileElement提供了正确的导入，作为IDE中正确的导入选项之一。如果我用mvn运行它就没有问题了。我认为这个问题与我对这个项目的依赖性有关。有没有人经历过这样的情况
# 1 楼答案
听起来，无论您在命令行中做什么，都没有包含构建它所需的类。在Eclipse中，您可能有对必要的JAR文件的引用
我的建议-如果您使用Maven来实现构建自动化（您应该这样做），那么应该完整地使用它，构建过程将自动为您完成所有这些
在您的情况下，我想只需确保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
