【问题描述】:
尝试在 Maven 项目中运行 Java 文件时遇到了问题。我在运行 Java 类的地方设置了它,该类在使用 run exec 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) 中正常运行程序,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 中运行良好并在 Mvn 命令上测试类。我尝试使用 Javac - cp 。看看新设置是否会消除错误,但我得到类似的错误。我环顾四周寻找了几个不同的答案,他们要么不'不要解决问题或让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,并确定解决此问题的最佳解决方案。
这是我的问题的一个示例,我尝试编译连接到我要运行的 Java 文件的 Java 文件之一,它将运行 Maven:
$ javac -d build/classes -sourcepath src -cp target/classes src/AppiumDriverSetUp_Lib/XMLMaker.java

6 errors
AppiumDriverSetUp_Lib 包中的 XMLMaker 文件:
import io.appium.java_client.AppiumDriver;
import io.appium.java_client.MobileElement;
public class XMLMaker {
public DocumentBuilderFactory docDriverSetup;
public DocumentBuilder driverSetup;
public int connectedDevices = 0;
public Document doc;
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer;
public void setupDriverXMLFile(List <AppiumDriver<MobileElement>> driverList) {
System.out.println("List size: "+ driverList.size());
try {
docDriverSetup = DocumentBuilderFactory.newInstance();
driverSetup = docDriverSetup.newDocumentBuilder();
doc = driverSetup.newDocument();
transformer = transformerFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, "http://testng.org/testng-1.0.dtd");

suiteElement.appendChild(rootElement);
rootElement.setAttribute("name", (String) driver.getCapabilities().getCapability("deviceId"));
Element deviceNameEle = doc.createElement("parameter");
deviceNameEle.setAttribute("name", "deviceName");
deviceNameEle.setAttribute("value", (String) driver.getCapabilities().getCapability("deviceId"));
rootElement.appendChild(deviceNameEle);

doc.appendChild(suiteElement);
} catch(ParserConfigurationException pce) {
pce.printStackTrace();
} catch (TransformerConfigurationException e) {
e.printStackTrace();
}
}
public void createDriverFile() throws TransformerConfigurationException, InterruptedException, IOException {
DOMSource source = new DOMSource(doc);
FileOutputStream streamNewFile = new FileOutputStream("./drivers.xml");
PrintWriter pw = new PrintWriter(streamNewFile);
StreamResult result = new StreamResult(pw);
try {
transformer.transform(source, result);
result.getWriter().close();
System.out.println("File Updated");
} catch (TransformerException e) {
e.printStackTrace();
System.out.println("Error updating the file");
} catch (IOException e) {
e.printStackTrace();
System.out.println("Unable to close output stream");
}
}
}
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
src\BaseTest\DriverTest.java:29: error: cannot access AppiumDriver
makeFile.setupDriverXMLFile(createDrivers.getActiveList());
^
class file for io.appium.java_client.AppiumDriver not found
1 error
BaseTest 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,它已经具有 AppiumDriver 和 MobileElement 的正确导入,作为我的 IDE 中正确的导入选项之一。如果我用 mvn 运行它也没问题。我认为问题与我对该项目的依赖关系有关。有没有人经历过这样的案例?
【问题讨论】:
-
你能用 XMLMaker.java 文件编辑你的问题吗?或者你也可以检查你在这个类中指定的包名可能是这个问题的原因。
-
@GauravRai1512 当然,我编辑问题以包含 XMLMaker 的 Java 文件,它在包中:AppiumDriverSetUp_Lib 和驱动程序测试,Whixh 在包中:BaseTest。我将添加未找到 bash/cmd 状态类的导入。
