Netbeans的蚂蚁环境变量 [英] Netbeans Ant environment variables

问题描述

我有在访问一个NetBeans的build.xml Ant脚本环境变量的一个问题。基本上，当我用这个code：

I am having a problem accessing environment variables in a netbeans build.xml ant script. Basically, when I use this code:

<target name="-pre-jar">

    <property environment="env"/>

    <echo message="${env.ANT_HOME}"/>
    <echo message="${env.JAVA_HOME}"/>

</target>

我收到输出如下：

I receive output as follows:

compile:
${env.ANT_HOME}
${env.JAVA_HOME}

这是一个问题，因为我以后需要访问这些文件路径中的脚本。而且，我相信，这两个被定义为环境变量。这是从我的终端一些证据：

This is a problem because I need to access those filepaths later in the script. Also, I am sure that those two are defined as environment variables. Here is some proof from my terminal:

Lukas-Rezeks-MacBook-Pro:ant lukas$ echo $JAVA_HOME - $ANT_HOME
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home - /ant

我做得不对的Ant构建脚本变量声明，还是我失去了一些东西明显？任何反馈将是AP preciated。谢谢你。

Am I doing something wrong in the ant build scripts variable declaration, or am I missing something obvious? Any feedback would be appreciated. Thanks.

推荐答案

您既可以把

<property environment="env"/>

你的目标之外，

或使用取决于=，而不是在你的编译任务antcall。

OR use "depends=" instead of "antcall" in your compile task.

我做了以下测试在我的Linux：

I did the following test on my Linux:

<target name="pre-jar">
    <property environment="env"/>
    <echo message="${env.ANT_HOME}"/>
    <echo message="${env.JAVA_HOME}"/>
</target>

<target name="compile">
    <antcall target="pre-jar" />
    <echo message="${env.ANT_HOME}"/>
    <echo message="${env.JAVA_HOME}"/>
</target>

当我跑了蚁族编译我得到了以下内容：

and when I ran "ant compile" I got the following:

编译：

pre-JAR：结果
      [回应] /opt/apache-ant-1.8.2结果
      [回应] /opt/jdk1.7.0结果
      [回应] $ {} env.ANT_HOME结果
      [回应] $ {} env.JAVA_HOME

pre-jar:
[echo] /opt/apache-ant-1.8.2
[echo] /opt/jdk1.7.0
[echo] ${env.ANT_HOME}
[echo] ${env.JAVA_HOME}

和当我用取决于=pre-JAR，结果是：

and when I used depends="pre-jar", the result was:

pre-JAR：结果
      [回应] /opt/apache-ant-1.8.2结果
      [回应] /opt/jdk1.7.0

pre-jar:
[echo] /opt/apache-ant-1.8.2
[echo] /opt/jdk1.7.0

编译：结果
      [回应] /opt/apache-ant-1.8.2结果
      [回应] /opt/jdk1.7.0

compile:
[echo] /opt/apache-ant-1.8.2
[echo] /opt/jdk1.7.0

当我提出任何目标之外，其结果是：

when I put outside any target, the result was:

编译：

pre-JAR：结果
      [回应] /opt/apache-ant-1.8.2结果
      [回应] /opt/jdk1.7.0结果
      [回应] /opt/apache-ant-1.8.2结果
      [回应] /opt/jdk1.7.0

pre-jar:
[echo] /opt/apache-ant-1.8.2
[echo] /opt/jdk1.7.0
[echo] /opt/apache-ant-1.8.2
[echo] /opt/jdk1.7.0
