Question

这是构建文件：

<exec executable="python" failonerror="true">
  <arg line="${installer.izpack.dir}/utils/wrappers/izpack2exe/izpack2exe.py"/>
  <arg line="--file=${basedir}/installer/EasyIT-installer.jar"/>
  <arg line="--output=${basedir}/installer/EasyIT-installer.exe"/>
  <arg line="--no-upx"/>
</exec>

输出：

BUILD FAILED

确保python位于正在运行构建的PATH中，或者在exec任务中指定python可执行文件的绝对路径。

有关使用Windows与非Windows的任何具体说明，请查看exec task的文档。请注意，那里提到了您的具体错误：

常见问题是PATH上没有可执行文件。如果您收到错误消息无法运行程序“...”：CreateProcess error = 2。该系统找不到指定的路径。看看你的PATH变量。只需在命令行上直接输入命令，如果Windows找到它，Ant也应该这样做。（否则请在用户邮件列表上寻求帮助。）如果Windows无法执行程序，请将程序目录添加到PATH（设置PATH =％PATH％; dirOfProgram）或在构建文件的可执行属性中指定绝对路径。

得到Ant构建错误：无法运行程序“python”
