传递“-J-Duser.language"通过ant进入javac，确保编译错误以正确的语言报告 [英] Passing "-J-Duser.language" into javac through ant to ensure compilation errors are reported in the correct language

问题描述

我的电脑目前设置为日语以进行测试.如果我的 java 项目有编译错误，则消息会以日语报告.

My PC is currently set up as Japanese for testing purposes. If my java project has a compilation error the message is reported in Japanese.

例如将 1 个源文件编译到 [...目录...][...class...].java:172: シンボルの见つけられません.

e.g. Compiling 1 source file to [...directory...] [...class...].java:172: シンボルを見つけられません。

我更愿意看到英文错误.

I would prefer to see the errors in english.

不使用 ant 的解决方法是使用javac -J-Duser.language=en [..java 文件...]这使得 javac 给出英文错误消息(-J 告诉 javac 将其余的参数传递给 java)

Without using ant the fix for this is to use javac -J-Duser.language=en [..java files...] which makes javac give english error messages (the -J tells javac to pass the rest of the argument to java)

我的问题是:我如何将它传递给 ant

My question is: how do I pass this to ant [editted to remove options I tried that didn't work]

推荐答案

尝试将 添加到您的 调用中.例如:

Try adding a <compilerarg> to your <javac> call. For example:

<javac srcdir="${src.dir}" destdir="${classes.dir}" fork="true">
    <compilerarg value="-J-Duser.language=en"/>
    <compilerarg value="-J-Duser.country=GB"/>
</javac> 

EDIT 修正了 arg 值.此外，这仅在编译器分叉时才有效；我更新了示例以反映这一点.

EDIT Fixed the arg values. Also, this only works if the compiler is forked; I updated the example to reflect that.
