如何根据 Eclipse 中的变量设置 Ant 属性? [英] How to set Ant properties based on variables in Eclipse?
问题描述
我有一个常见问题，可能有无数种方法可以解决它.我正在为这种典型情况寻找一种优雅、简单的解决方案:
I have a common problem and there are probably countless ways to solve it. I'm looking for an elegant, simple solution to this typical scenario:
我在 Eclipse 中有一个带有 Ant 构建文件 (build.xml) 的项目，该构建文件使用一个属性文件 (build.properties).在那个属性文件中，我想设置一个指向eclipse项目根目录的属性，例如:
I have a project in Eclipse with an Ant build file (build.xml) the build file uses a property file (build.properties). In that property file, I want to set a property that points to the root directory of the eclipse project such as:
project.root = /path/to/eclipse/workspace/projectName
或者最好:
project.root = ${path.to.eclipse.workspace}/projectName
我该如何做到这一点:
- 在具有不同路径到项目根目录的不同机器上工作(即在团队环境中)
- 允许在 eclipse 中执行 ant build.xml 文件
- 允许 ant build.xml 文件在 eclipse 之外执行(即从命令行)
- 允许 build.properties 文件存在于项目根目录以外的目录中
推荐答案
我想我正在寻找的是将以下内容添加到 build.properties 文件中:
I think what I'm looking for is to add the following to the build.properties file:
project.root = ${basedir}
或者，我可以在需要 project.root 时使用 basedir 属性.
alternatively, I can just use the basedir property whenever project.root is needed.
我碰巧在看ivy.properties 的源代码，我看到正在使用 basedir 属性.我刚刚测试并验证了这个属性在 eclipse 内部和命令行以及从不同目录调用 ant 时在不同的机器上工作，例如:
I happened to be looking at the source code for ivy.properties and I saw the basedir property being used. I just tested and verified that this property works on different machines both from inside eclipse and from the command line as well as when making a call to ant from a different directory such as:
ant -f /path/to/eclipse/workspace/projectName/build.xml
一分钟后，我将验证在不同位置(例如在 src/main/resources/config/ivy/ivysettings.xml 中)导入属性文件时这是否也有效.
When I get a minute, I will verify that this also works when importing the property file in different locations (such as inside src/main/resources/config/ivy/ivysettings.xml).
