c - ant target exec 失败，而在 shell 上运行命令成功

Question

我得到了一个针对不同目标平台和主机平台运行的构建环境，使用 ant 来完成主要工作。对于一个目标平台(高通的 BREW MP，原生 C/C++)，我需要用这个 ant 目标执行编译:

<target name="build.brew.target" if="${cfg.build.brew}" depends="brew.clean">
  <exec dir="${src.cpp.brew}/brew" executable="cs-make" failonerror="true" newenvironment="false">
    <env key="PATH" value="${env.PATH}" />
    <arg line="-f brew.mak" />
  </exec>
...
</target>

cs-make 是来自 BREW SDK 的 make 实用程序，可运行在 makefile (brew.mak) 中定义的构建。
从 cmd 提示符 (Win7/64) 执行时，ant 返回错误，比如

ant build.brew.target

ant 打印出 cl.exe(Visual Studio 2010 Express 的一部分)报告的错误:

我找不到关于错误 -1073741515 的任何信息，所以我不知道问题出在哪里。但是:如果我运行相同的命令(在与之前调用 ant 时相同的 cmd 窗口中)，一切正常。

cs-make -f brew.mak

我的第一个想法是 - 并且仍然是我最好的选择 - 它一定与我的环境有关。为此，我将 newenvironment="false" 添加到我的 exec 行。没有成功。
欢迎任何提示...

Answer 1

这是一个工作太晚的问题。我第一次遇到这个错误后，我认为它一定是 %PATH% 或其他环境变量。所以我添加了这一行:

<env key="PATH" value="${env.PATH}" />

我从我项目的其他地方复制了这个，但没有交叉检查它是否为我的环境保留了正确的 %PATH%。
由于它不起作用，我用谷歌搜索并找到了 exec 目标的参数 newenvironment="false" 并添加了它 - 但由于目标中的上述行没有包含正确的 env.PATH 值, 出错了。

这对我有用:

<target name="build.brew.target" if="${cfg.build.brew}" depends="brew.clean">
  <exec dir="${src.cpp.brew}/brew" executable="cs-make" failonerror="true" newenvironment="false">
    <arg line="-f brew.mak" />
  </exec>
  ...
</target>
