我在 Eclipse 中有一个项目,它使用 ant 来编译和 jar 类文件和引用的 jar。使用eclipse中默认java builder生成的class文件生成的jar文件工作正常,但是使用ant编译源码然后jar结果时,报错“错误:尝试打开文件时发生意外错误... ....jar" 在目标构建上执行 java -jar 时产生结果。有谁知道我做错了什么?下面是构建 xml 内容。这是我传递给 ant 的论点

-DInTouchV.SrcPath=${InTouchV.SrcPath} -DInTouchV.DropPath=${workspace_loc:/InTouchVTransferService/dist}

<project default="create_run_jar" name="Create Runnable Jar for Project InTouchVTransferService">
<!--this file was created by Eclipse Runnable JAR Export Wizard-->
<!--ANT 1.7 is required                                        -->
<property name="Version" value="1.3"></property> 
<tstamp>
    <format property="TODAY" pattern="yyyy-MM-dd HH:mm:ss" />
</tstamp>
<target name="Compile_Source">
    <javac srcdir="${InTouchV.SrcPath}/InTouchVTransferService/src"
                     destdir="${InTouchV.SrcPath}/InTouchVTransferService/bin"
                     classpath="${InTouchV.SrcPath}/lib/AtomClasses.jar"
                     debug="on"
                    includeantruntime="yes"
                    />

    <echo file="${InTouchV.DropPath}/Version.txt">${Version}</echo>
</target>
</project>

发现问题,属性“JVM Version”包含一个空格。去掉空格,jar文件正确执行。老实说,我不能说为什么 eclipse + ant jar 的默认 java builder 可以与空间一起使用,但 ant build + ant jar 没有。至少它是固定的:D
