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

标签：

有如下ant的target，为了执行java代码

	<target name="shanhy" depends="compile">
		<!-- 指明要调用的java类的名称 -->
		<java classname="Test" fork="true" failonerror="true">
			<!-- 指明要调用的java类的class路径 -->
			<classpath path="F:\androidWorkspace\apkPacker\bin">
			</classpath>
		</java>
	</target>

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] ????: ?????????????????? Test

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

Total time: 1 second

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（<sysproperty key="file.encoding" value="UTF-8" />） 后，控制台就可以正常显示中文了，如下：

	<target name="shanhy" depends="compile">
		<!-- 指明要调用的java类的名称 -->
		<java classname="Test" fork="true" failonerror="true">
                        <sysproperty key="file.encoding" value="UTF-8" />
			<!-- 指明要调用的java类的class路径 -->
			<classpath path="F:\androidWorkspace\apkPacker\bin">
			</classpath>
		</java>
	</target>

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

	public static void main(String[] args) {
		System.out.println(args[0]);
