Java ant 脚本不显示警告 [英] Java ant script does not show warnings

问题描述

我有一个 1.4 java 代码，我想用 1.5 编译器编译它，因为我想查看所有警告消息.我在 javac 中添加了 -Xlint 选项，但输出似乎没有变化，但我知道代码中至少有几个警告.

I have a 1.4 java code and I want to compile it with a 1.5 compiler because I would like to see all warning messages. I added the -Xlint option to javac, but it seems there were no changes in the output, but I know there is at least a couple of warnings in the code.

我将这两行添加到我的 ant 脚本的编译目标标签中:

I added these two lines to my ant script's compile target tag:

<compilerarg value="-Xlint:all"/>
<compilerarg line="-Xmaxwarns 10000"/>

感谢您的回答.

推荐答案

您同时使用了 value 和 line 属性.Compilerarg 需要正是其中之一"，请参阅文档.尝试只使用一行，例如:<compilerarg line="-Xlint:all -Xmaxwarns 10000"/>

You have used value and line attributes at the same time. Compilerarg requires "Exactly one of these", see docs. Try using only line, like: <compilerarg line="-Xlint:all -Xmaxwarns 10000"/>
