javac的：将警告视为错误 [英] Javac: Treat warnings as errors

问题描述

我有我的编译程序中的Ant文件。我想如果有警告报道编译器javac任务失败。如何做到这一点任何线索？

I have an Ant file that compiles my program. I want the javac task to fail if any warning was reported by the compiler. Any clue on how to do that?

推荐答案

使用 -Werror 标记。这不是在 -help 输出中，但它的作品。

Use the -Werror flag. It's not listed in the -help output, but it works.

我发现它通过此博客条目​​以及我自己的测试code（在NetBeans使用Ant）。输出是：

I found it through this blog entry and tested on my own code (in NetBeans with Ant). The output was:

MyClass.java:38: warning: [serial] serializable class MyClass has no definition of serialVersionUID
public class MyClass extends JComponent {
1 warning
BUILD FAILED (total time: 3 seconds)

请注意，这是Java的6只，​​虽然。

Note that this is Java 6 only, though.

修改：在Ant构建指定此实例：

Edit: Example of specifying this in Ant buildfile:

<javac srcdir="${src.dir}" destdir="${classes.dir}" classpathref="classpath">
    <compilerarg value="-Xlint:all"/>
    <compilerarg value="-Werror"/>
</javac>
