Eclipse 中 Ant 的动态 basedir [英] Dynamic basedir for Ant in Eclipse

问题描述

标题可能不是最好的，所以让我解释一下我想要做什么.

The title might not be the best so let me explain what I am trying to do.

我制作了一个 Ant 构建文件，它将帮助我实现 Maven 目标.将范围限定到 Ant 视图并选择我想要做的事情要容易得多.这样做的最大好处是我几乎可以在任何项目中使用它.无论我是部署到 tomcat、jboss 或 sakai(:deploy) 还是我处理同一服务器的多个实例或跳过测试......最坏的情况我只是更改一些路径属性.

I have made an Ant buildfile that will help me with Maven goals. It's so much easier having to scope to Ant view and choose what I want to do. The biggest benefit with this is that I can use it in almost any project. Whether I deploy to tomcat or jboss or sakai(:deploy) or I handle mutiple instaces of the same server or skip tests... worst case I just change some path properties.

现在的缺点是我必须在每个项目中保留此构建文件的副本.

The drawback right now is that I have to keep a copy of this buildfile in every project.

我想要做的是在工作区中只有 1 个构建文件，并且从 eclipse 中选择了我正在处理的当前项目.无论是模块还是父级，我都可以稍后对其进行改进.所以基本上是根据eclipse中选择的项目改变ant任务的basedir.

What I am trying to do is have only 1 buildfile, in the workspace, and dinamicaly optain, from eclipse, the current project that I am working on. Be it module or parent I can refine that later. So basically change the basedir for ant tasks based on the selected project in eclipse.

我尝试过 Ant 运行时属性，但由于某些原因，像

I have tried Ant Runtime Properties but for some reason properties like

${project_path}

${project_path}

未能给我他们的描述.我明白了:

fail to give me what their description say. I get this:

变量引用空选:${project_path}

Variable references empty selection: ${project_path}

我希望我想做什么很清楚.所以我的问题，我知道这是可能的，我只是遗漏了一些东西，我希望你们中的一些人可以帮助我.

I hope it is clear what I am trying to do. So my question, I know it's possible, I'm just missing something and I hope some of you can help me with this.

我相信问题出在 Ant 运行时属性上.我不是 100% 确定我应该如何使用它们.

I believe the trouble is in the Ant Runtime properties. I'm not 100% sure how I should use those.

谢谢！

推荐答案

EDIT 经过评论和进一步调查..
使 projectdir 可用作 ant 的 basedir 属性，如下所示:
<代码>窗口 >首选项蚂蚁>运行时属性
并创建一个名为 basedir 的属性，其值为:

EDIT after comment and further investigation..
Make the projectdir available as basedir property for ant like that :
Window > Preferences > Ant > Runtime > Properties
and create a property named basedir with value either :

${project_loc}
或
${workspace_loc}/${project_name}

和

<project basedir="${basedir}">
 <echo>$${basedir} = ${basedir}</echo>
</project>

将按预期工作，意味着回显 eclipse/yourworkspace/projectdir

will work as expected, means echoing eclipse/yourworkspace/projectdir

也许还有其他方法，即通过 Ant Addon Ant4Eclipse，旨在使 Eclipse 设置可用于 ant，没用过.

Maybe there are other ways, i.e. via Ant Addon Ant4Eclipse, which aims to make Eclipse settings available for ant, never used it.
