Java – Netbeans中的大规模在线分析：无法访问仪器环境

public class JavaApplication10_MOA {

        public JavaApplication10_MOA(){            
        }

        public void run(int numInstances,boolean isTesting){
                Classifier learner = new HoeffdingTree();
                RandomRBFGenerator stream = new RandomRBFGenerator();
                stream.prepareForUse();

                learner.setModelContext(stream.getHeader());
                learner.prepareForUse();

                int numberSamplesCorrect = 0;
                int numberSamples = 0;
                boolean preciseCPUTiming = TimingUtils.enablePreciseTiming();
                long evaluateStartTime = TimingUtils.getNanoCPUTimeOfCurrentThread();
                while (stream.hasMoreInstances() && numberSamples < numInstances) {
                        Instance trainInst = stream.nextInstance().getData();
                        if (isTesting) {
                                if (learner.correctlyClassifies(trainInst)){
                                        numberSamplesCorrect++;
                                }
                        }
                        numberSamples++;
                        learner.trainOnInstance(trainInst);
                }
                double accuracy = 100.0 * (double) numberSamplesCorrect/ (double) numberSamples;
                double time = TimingUtils.nanoTimeToSeconds(TimingUtils.getNanoCPUTimeOfCurrentThread()- evaluateStartTime);
                System.out.println(numberSamples + " instances processed with " + accuracy + "% accuracy in "+time+" seconds.");
        }        

        public static void main(String[] args) throws IOException {
                JavaApplication10_MOA exp = new JavaApplication10_MOA();
                exp.run(1000000,true);
        } 

}

这是输出：

Can not access instrumentation environment. Please check if jar file
containing SizeOfAgent class is specified in the java’s “-javaagent”
command line argument. 1000000 instances processed with 91.0458%
accuracy in 5.5 seconds. BUILD SUCCESSFUL (total time: 5 seconds)

问题是Netbeans无法访问仪器环境,我理解这与配置文件类似.我已经尝试了Netbeans how to set command line arguments in Java的建议,转到Run – >设置项目配置 – >定制.将参数设置为-javaagent：sizeofag.jar.但它不起作用！
