Ant mkdir 失败

Question

我是蚂蚁的新手。请突出显示我的 build.xml 中出现的问题。任何帮助表示赞赏。谢谢。

问题：我想要创建的文件夹保留在当前目录的上层创建。

• ant 版本：1.8.0
• 平台：LinuxMint 10.10
• java 版本“1.6.0_20”
• OpenJDK 运行时环境 (IcedTea6 1.9.9) (6b20-1.9.9-0ubuntu1~10.10.2)
• OpenJDK Server VM (build 19.0-b09，混合模式)

build.xml：

<property name="prj.root"       value="." />
<property name="build.dir"      value="${prj.root}/build"/>
<property name="build.docs"     value="${build.dir}/docs"/>
<property name="build.models"   value="${build.dir}/models"/>
<property name="build.projects" value="${build.dir}/projects"/>
<property name="dist.dir"       value="${prj.root}/dist"/>

<target name="clean">
    <delete dir="${build.dir}" />
    <delete dir="${dist.dir}" />
</target>

<target name="init" depends="clean" description="initialization target">
    <echo message=">> Build JAS  ${jas.version} at ${prj.root}"/>
    <echo message="build.dir = ${build.dir}" />
    <mkdir dir="${build.dir}"/>
    <mkdir dir="${build.docs}" />
    <mkdir dir="${build.models}" />
    <mkdir dir="${build.projects}" />
    <mkdir dir="${dist.dir}"/>
</target>

执行+输出：

yamhon@yamhon-g410 ~/projects/JAS $ ant init

Buildfile: /home/yamhon/projects/JAS/build.xml

clean:
   [delete] Deleting directory /home/yamhon/projects/build
   [delete] Deleting directory /home/yamhon/projects/dist

init:
     [echo] >> Build JAS  ${jas.version} at .
     [echo] build.dir = ./build
    [mkdir] Created dir: /home/yamhon/projects/build
    [mkdir] Created dir: /home/yamhon/projects/build/docs
    [mkdir] Created dir: /home/yamhon/projects/build/models
    [mkdir] Created dir: /home/yamhon/projects/build/projects
    [mkdir] Created dir: /home/yamhon/projects/dist

有两件事你可以尝试。

1) 解决你的亲戚'.'通过将路径分配给具有位置属性的属性。

<property name="my.path" location="."/>
<echo message="my.path = ${my.path}"/>

2) 使用 build in basedir 属性，该属性指向 build.xml 文件本身的目录。

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

这应该会让你继续下去:)
