使javac将警告视为错误 [英] Make javac treat warnings as errors

问题描述

我有一个Ant文件可以编译我的程序.如果编译器报告了任何警告，我希望javac任务失败.关于如何做到这一点的任何线索?

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标志.它未在-help输出中列出，但可以使用.

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

我通过此博客条目找到了它，并且在我自己的代码上进行了测试(在带有Ant的NetBeans中).输出为:

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)

但是请注意，这仅是Java 6.

Note that this is Java 6 only, though.

编辑:在Ant构建文件中指定此示例:

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>
