问题描述
我想将apache cli添加到我的应用程序中,但是我遇到了问题.这些错误会在我尝试运行时显示:
I want to add apache cli to my application, but I have problem. These errors show when I try to run it:
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();
}
我还在pom.xml中添加了以下内容:
I also added in pom.xml this:
<dependency>
<groupId>commons-cli</groupId>
<artifactId>commons-cli</artifactId>
<version>1.2</version>
</dependency>
但这无济于事://我也首先手动添加了commons-cli-1.3.1.jar和后来的commons-cli-1.2.jar,但这两者都无济于事.
But it doesn't help :/ Also I added manually firstly commons-cli-1.3.1.jar and later commons-cli-1.2.jar but both doesn't help.
@edit
Ps.我将其作为"java -jar filename.jar"运行.
Ps. I'm running it as "java -jar filename.jar".
推荐答案
只需几分钟的更改,我就能执行以下代码:-
With few minute changes I am able to execute this code:-
CommandLineParser parser = new PosixParser();
Options options = new Options();
options.addOption("a", true, "First parameter");
args=new String[]{"-a abc"};
try {
CommandLine commandLine = parser.parse(options, args );
System.out.println(commandLine.getOptionValue("a"));
} catch (ParseException e1) {
e1.printStackTrace();
}
Output :- abc
在我的pom.xml中:-
In my pom.xml :-
<dependency>
<groupId>commons-cli</groupId>
<artifactId>commons-cli</artifactId>
<version>1.2</version>
</dependency>
commons-cli-1.2.jar对您的代码不可见.
commons-cli-1.2.jar is not visible to your code.
