eclipse中ant build 控制台乱码解决解决方法(ant执行java)

有如下ant的target,为了执行java代码

	
		
		
			
			
			
		
	

上面代码中,classname应该写java类包括包名的名称“ com.shanhy.demo.packers.Test ”,我故意写错只写“ Test ”

在eclipse中使用ant 执行该target  的时候,会出现如下乱码。

Buildfile: F:\androidWorkspace\Packers\build.xml
Trying to override old definition of task dex-helper
compile:
    [javac] F:\androidWorkspace\Packers\custom_rules.xml:59: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds
shanhy:
     [java] ����: �Ҳ������޷��������� Test

BUILD FAILED
F:\androidWorkspace\Packers\custom_rules.xml:64: Java returned: 1

Total time: 1 second

在实际项目开发中,我们可能会用到很多中文的地方,可能会经常出现这样乱码的情况,导致我们无法正确的判断具体的错误原因。

解决方法就是 在运行时修改ant 的运行时输出编码,我们添加() 后,控制台就可以正常显示中文了,如下:


	
		
		
                        
			
			
			
		
	

输出如下:

Buildfile: F:\androidWorkspace\Packers\build.xml
Trying to override old definition of task dex-helper
compile:
    [javac] F:\androidWorkspace\Packers\custom_rules.xml:59: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds
shanhy:
     [java] 错误: 找不到或无法加载主类 Test

BUILD FAILED
F:\androidWorkspace\Packers\custom_rules.xml:64: Java returned: 1

Total time: 1 second

我们现在将 classname 修改正确,如下:

Buildfile: F:\androidWorkspace\Packers\build.xml
Trying to override old definition of task dex-helper
compile:
    [javac] F:\androidWorkspace\Packers\custom_rules.xml:59: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds
shanhy:
     [java] 单红宇
BUILD SUCCESSFUL
Total time: 1 second

测试的Java 类代码为:

package com.shanhy.demo.packers;

public class Test {

	/**
	 * 测试
	 * 
	 * @param args
	 * @author SHANHY
	 * @date   2015-8-18
	 */
	public static void main(String[] args) {
		System.out.println(args[0]);
	}

}
