java – 使用Ant执行绝对路径而不是相对路径

前端之家收集整理的这篇文章主要介绍了java – 使用Ant执行绝对路径而不是相对路径前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我的Ant脚本中有以下代码段.它执行得很好:
<exec executable="C:\test\foo\programName.exe" />

但是当我尝试通过设置目录来执行它时,如下所示:

<exec executable="programName.exe"
  dir="C:\test\foo\" />

我明白了:

Execute Failed: java.io.IOException:@H_403_12@ Cannot run program “programName.exe”@H_403_12@ (in directory “C:\test\foo”):@H_403_12@ CreateProcess error=2,The system@H_403_12@ cannot find the file specified

请帮忙!为什么单独指定目录时它不起作用?

解决方法

添加resolveexecutable属性
<exec executable="programName.exe" 
  resolveexecutable="true"
  dir="C:\test\foo\" />

resolveexecutable When this@H_403_12@ attribute is true,the name of the@H_403_12@ executable is resolved firstly against@H_403_12@ the project basedir and if that does@H_403_12@ not exist,against the execution@H_403_12@ directory if specified. On Unix@H_403_12@ systems,if you only want to allow@H_403_12@ execution of commands in the user’s@H_403_12@ path,set this to false. since Ant 1.6@H_403_12@ No,default is false
