为什么我的 build.properties 中的值没有通过我的 ant 构建传播？

Question

我一直在研究一个用 ant 构建的 Java 项目，直到最近它都运行完美。现在我遇到了一些我不明白的错误（我是 ant 的新手），而且似乎有很多这样的错误。我已经挑出了其中一个，但潜在问题可能还有更多问题，所以如果我没有提供足够的信息，请向我询问更多信息。 =)

我解决的问题与我的 build.properties 文件、调用它的 commonbuild.xml 以及整个项目的根 build.xml 有关。当我从这样的命令行运行 ant 时：

> ant

它输出：

（除了前 10 行我不会显示所有内容，但有人告诉我始终显示操作的完整输出）

在这里您可以看到我的调试尝试中的一些 echos。如果您查看 OUTPUT_DIR 的值，它评估为 classes，env.EMV_VOBS 和 JAR_OUTPUT_DIR 也是如此，但 DEBUG_ON 和 DEBUG_LVL 没有.这就是问题所在...并非 build.properties 中的所有值都被使用。

如果我运行蚂蚁是这样构建的：

>ant -propertyfile ./ant/build.properties

它输出这个：

这对我来说很奇怪，因为 commonbuild.xml

的第三行

<property file="${env.EMV_VOBS}/emv/ant/build.properties"/>

应该导入我的 build.properties 文件，它有点...如果您查看 > ant 的输出，您会看到 OUTPUT_DIR = classes来自 build.properties 我假设。

所以...

为什么 build.properties 中的某些值被使用而其他值没有被使用？
您还发现这些文件还有哪些其他问题？

这只是看起来很多的第一期，所以欢迎对下面的代码提出任何批评；我想尽我所能了解这些文件。

Answer 1

对于那些感兴趣的人，我找到了问题的根源。

我在一台有多个分支的机器上工作。我被要求在我的机器上的 Main 分支中做一些事情，并设置一些环境变量，然后转到下一个问题。几周后，这些 ant 文件使用了相同的环境变量，当我去构建我的 Dev 分支时，我忘记了记住其中一个变量的重要性。我只改了一个，当然这是最重要的一个。 =/

所以最后，我尝试使用另一个代码库的 build.xml 文件编译一个代码库，并手动传递我的 build.properties，这进一步混淆了我的问题所在。这方面的教训？当我遇到问题时，我需要真正检查我的环境，而不仅仅是假设我已经正确设置了所有内容。

谢谢你看完我的遭遇，我要躲到角落里去了。 =)

为什么我的 build.properties 中的值没有通过我的 ant 构建传播？

Why are values in my build.properties not propagating through my ant build?
