我在一个依赖项jar中替换了.class文件后，蚂蚁构建失败并编译失败

我是Ant的新手，当前有一个新的Java Web应用程序构建，需要ant的支持，一个Web应用程序依赖于b Web应用程序，并将其作为JAR依赖项添加到lib文件夹中，因此如果有一些更新在b上，那么我需要重建b并生成一个新的JAR，然后替换a的依赖项。

就像我说的那样，我在b应用程序的一个Java文件中更改了一点代码，然后进行编译，然后解压缩b JAR依赖项以替换该类文件并将其重新压缩为JAR文件。当我构建它时，会发生错误并显示编译失败。

根据JDK1.6这两个Java应用程序，加上我也检查jar文件的源代码是JDK 1.6，所以我使用JDK 1.6编译javac updatedJava.java，还有一件事是，如果我不取代这个类文件，它可以在Jenkins中成功构建，而一旦我更新了该类文件，它将失败。

我真的不熟悉Ant。这是我的应用程序详细信息和一些错误日志：

答案 0 :(得分：0)

当类路径上有一个无效的jar时，它将被静默忽略。鉴于您遇到了一堆构建错误，这听起来像是在发生：您的代码取决于该jar中的类，并且该jar由于无效而实际上消失了。

尤其是在早期的Java版本中，“一个jar只是一个zip文件”并不是真的：虽然解压缩可以成功解压缩一个jar，但是使用“ zip”工具生成的任何旧zip文件不一定是有效的jar。

我将从使用jar工具（而不是zip）开始添加/替换类文件。
