当我尝试运行具有外部依赖关系而不是外部依赖关系的jar文件时,我尝试使用下面的代码修复"Error: No manifest attribute"
。
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
...
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>Driver</mainClass>
</manifest>
</archive>
</configuration>
...
</plugin>
</plugins>
但是,每次我清洗,编译,打包并运行jar时,都将执行。它一直在说:
Error: Could not find or load main class com.harriott.Driver
Caused by: java.lang.ClassNotFoundException: Driver
P.S。我只有一个带有Public static void main方法的类,它名为Driver:

这是我的Java代码:

public class Driver {

*
* @param "args[1]", bypass cache flag. If set to:
*
* "true", the cspm client will call the cspm server system
*
* "false", the cspm client will 1st search the local cache
*@param "args[2]", xmlOption. (Optional) If set to:
*
* "-x", Gives the XML data.
* @return int 0 if successful, 100 if an exception ocurred, otherwise
* documented error codes for the CSPMClient class.
*
*/
public static void main(String[] args) {
try {
CSPMClient testInterface = new CSPMClient();
System.out.println("------------------------------------");
System.out.println(testInterface.getAllCredentials());
//System.out.println(testInterface.retrieveCredentials("emc_grab",true));
System.out.println("------------------------------------");
//get the result
String statusCode = testInterface.getStatusCode();
String userId = testInterface.getUserId();
String password = testInterface.getPassword();
String xmlData = testInterface.getXMLData();
System.out.println("Status Code: " + statusCode);
System.out.println("UsedId: " + userId);
System.out.println("Password: " + password);
System.out.println("XML Data: " + xmlData);
//set the return value
if (statusCode.equals("400")) {
System.out.println("PASSED");
System.exit(0);
} else {
System.out.println("FAILED");
System.exit(Integer.parseInt(statusCode));
}
} catch(Exception e) {
e.printStackTrace();
System.exit(100);
}catch(UnsatisfiedLinkError unsatisfiedLinkError){
System.out.println("UnsatisfiedLinkError>>>>");
System.out.println(unsatisfiedLinkError.getMessage());
}
}
}
我也会收到此错误:
