"java"成功". java emmarun"失败了 [英] "java" succeeds," java emmarun" fails

问题描述

免责声明:我是java和emma的新手.详细信息:

Disclaimer: I am new to java and emma. Details:

• 我安装了emma，并完成了一些示例.没问题.
• 我有一个Java项目，其中包含许多文件，希望获得一份覆盖率报告.
• 我键入"javac -d out * .java".没有错误.
• 我键入"java -cp out Main".程序运行正常，我得到了预期的输出.

• 我键入"java emmarun -cp out Main".我得到以下信息:

• I installed emma, and have worked through some of the examples. No problems.
• I have a java project with a number of files that I wish to get a coverage report.
• I type "javac -d out *.java". No errors.
• I type "java -cp out Main". The program runs fine and I get the expected output.

• I type "java emmarun -cp out Main". I get the following:

emmarun:[MAIN_METHOD_NOT_FOUND]应用程序类[Main]没有可运行的公共main()方法 线程"main" com.vladium.emma.EMMARuntimeException中的异常:[MAIN_METHOD_NOT_FOUND]应用程序类[Main]执行 没有可运行的public main()方法 在com.vladium.emma.rt.AppRunner._run(AppRunner.java:546) 在com.vladium.emma.rt.AppRunner.run(AppRunner.java:97) 在com.vladium.emma.runCommand.run(runCommand.java:247) 在emmarun.main上(emmarun.java:27) 引起原因:java.lang.IllegalAccessException:类com.vladium.emma.rt.AppRunner $ Invoker无法访问clas成员 s主修饰语"public static" 在sun.reflect.Reflection.ensureMemberAccess(未知来源) 在java.lang.reflect.AccessibleObject.slowCheckMemberAccess(未知来源) 在java.lang.reflect.AccessibleObject.checkAccess(未知来源) 在java.lang.reflect.Method.invoke(未知来源) 在com.vladium.emma.rt.AppRunner $ Invoker.run(AppRunner.java:655) 在java.lang.Thread.run(未知来源)

我的"Main.java"文件如下所示:

My "Main.java" file looks like this:

public class Main {
    public static void main( String[] args ) {
        NetworkSimplexTest nst = new NetworkSimplexTest();
        nst.test();
    }
}

我会发布所有代码，但是很长.我尝试过的简单示例可以正常工作-emma会自动检测并创建覆盖报告，就像示例中一样.

I would post all the code, but it is rather lengthy. The simpler examples I tried work fine - emma automatically instruments and creates a coverage report, just like in the examples.

看来Emma找不到我的"Main"，但是普通的Java可以找到.我想念什么?

It appears that Emma cannot find my "Main", but regular java can. What am I missing?

推荐答案

Emma希望将该类定义为public，而您的原始代码中缺少该类.

Emma will expect the class to be defined as public, which was missing in your original code.
