我正在尝试使用Ant构建脚本构建Web应用程序。应用程序具有许多模块，在编译几个项目后，构建失败并显示以下错误日志：
[javac]编译器（1.4.2）中发生异常。检查错误游行中的重复项后，请在Java开发人员连接（http://java.sun.com/cgi-bin/bugreport.cgi）中提交错误。在报告中包括您的程序和以下诊断。谢谢。 [javac] java.lang.ArrayIndexOutOfBoundsException：25459
这是一个Java 4应用程序。尝试使用 Ant 1.7和1.8 版本构建它，但都失败，并出现相同的错误。
这是完整的堆栈跟踪：
[javac] An exception has occurred in the compiler (1.4.2). Please file a bug at the Java Developer Connection (http://java.sun.com/cgi-bin/bugreport.cgi) after checking the Bug Parade for duplicates. Include your program and the following diagnostic in your report. Thank you.

答案 0 :(得分：1)
经过两天的努力，终于找到了问题。这是由JAR中的 .class 文件重复引起的。这是非常奇怪的，因为我已经看到蚂蚁任务在打包JAR时会复制重复的.class文件（在详细模式下带有警告-v）。这是构建脚本文件中的罪魁祸首：
<jar destfile="${dir_dest}" manifest="${dir_src}/META-INF/MANIFEST.MF">
<fileset dir="${dir_dest}" />
<fileset dir="${dir_src}" excludes="**/*.java"/>
</jar>
删除后脚本成功运行：
<fileset dir="${dir_dest}" />
