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

Question

我一直在开发一个使用 ant 构建的 Java 项目，直到最近它都运行得非常完美。现在我遇到了一些我不明白的错误(我是 Ant 的新手)，而且似乎有很多错误。我已经梳理出了其中之一，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。 =)

我已经弄清楚的问题与我的 build.properties 文件、调用它的 commonbuild.xml 以及根 build.xml 整个项目。当我从命令行运行 ant 时，如下所示:

> ant

它输出:

(除了前 10 行之外，我不会显示所有内容，但我被告知要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回显。如果您查看 OUTPUT_DIR 的值，它会评估为 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。

如果我像这样运行 ant 构建:

>ant -propertyfile ./ant/build.properties

它输出:

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......如果你查看 > ant 的输出，你会看到 OUTPUT_DIR = classes 我认为是从 build.properties 获取的。

所以...

• 为什么 build.properties 中的某些值被使用，而其他值却没有被使用？
• 您还发现这些文件存在哪些其他问题？

这只是第一期，所以欢迎对下面的代码提出任何批评；我想尽我所能地了解这些文件。

Answer 1

对于那些感兴趣的人，我找到了问题的根源。

我正在一台具有多个分支的机器上工作。我被要求在我的机器上的主分支中做一些事情，并设置一些环境变量，然后继续下一期。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，我忘记了其中一个变量的重要性。除了一处之外，我都改变了，当然这是最重要的一处。 =/

所以最后，我尝试使用另一个代码库的 build.xml 文件来编译一个代码库，并手动传递我的 build.properties ，这进一步混淆了我的问题。这其中的教训是什么？当遇到问题时，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。

感谢您阅读我的困境，我要躲到角落里去。 =)
