java.lang.NoClassDefFoundError: org/apache/commons/cli/ParseException
我想将apache cli添加到我的应用程序中,但我有问题。当我尝试运行它时,会出现这些错误:
Error: A JNI error has occurred, please check your installation and try again

这是我的代码:
CommandLineParser parser = new PosixParser();
Options options = new Options();
options.addOption("a", "abc", true, "First parameter");
try {
CommandLine commandLine = parser.parse(options, args);
System.out.println(commandLine.getOptionValue("a"));
} catch (ParseException e1) {
e1.printStackTrace();
}
我还添加了pom.xml这个:
<dependency>
<groupId>commons-cli</groupId>
<artifactId>commons-cli</artifactId>
<version>1.2</version>
</dependency>
但这无济于事:/此外,我首先手动添加了commons-cli-1.3.1.jar,后来又添加了commons-cli-1.2.jar但两者都没有帮助。
@edit
Ps. 我把它作为“java -jar filename.jar”运行。
