ANT - 你如何改變src.dir屬性？

Question

我正在嘗試使用本地build.xml文件構建一個Android項目。裏面我有：

<property name="src.dir" value="test"/> 

我運行Ant如下：

ant debug 

然後我得到一個錯誤，說明該文件夾「src」中不存在。爲什麼Ant忽略我試圖設置的src.dir屬性？我想讓它看看'測試'文件夾裏的我的來源，而不是'src'文件夾。

我的build.xml與我正在執行'ant debug'的文件夾相同。以下是錯誤我得到：

BUILD FAILED 
/Android/sdk/tools/ant/build.xml:653: The following error occurred while executing this line: 
/Android/sdk/tools/ant/build.xml:659: /Work/TT/android-TT/app/src/main/src does not exist. 

這裏是其中進口標準的Android的build.xml我的build.xml文件：

<?xml version="1.0" encoding="UTF-8"?> 
<project name="app" default="help"> 

    <property name="src.dir" value="test"/> 

    <!-- The local.properties file is created and updated by the 'android' tool. 
     It contains the path to the SDK. It should *NOT* be checked into 
     Version Control Systems. --> 
    <property file="local.properties" /> 

    <!-- The ant.properties file can be created by you. It is only edited by the 
     'android' tool to add properties to it. 
     This is the place to change some Ant specific build properties. 
     Here are some properties you may want to change/update: 

     source.dir 
      The name of the source directory. Default is 'src'. 
     out.dir 
      The name of the output directory. Default is 'bin'. 

     For other overridable properties, look at the beginning of the rules 
     files in the SDK, at tools/ant/build.xml 

     Properties related to the SDK location or the project target should 
     be updated using the 'android' tool with the 'update' action. 

     This file is an integral part of the build system for your 
     application and should be checked into Version Control Systems. 

     --> 
    <property file="ant.properties" /> 

    <!-- if sdk.dir was not set from one of the property file, then 
     get it from the ANDROID_HOME env var. 
     This must be done before we load project.properties since 
     the proguard config can use sdk.dir --> 
    <property environment="env" /> 
    <condition property="sdk.dir" value="${env.ANDROID_HOME}"> 
     <isset property="env.ANDROID_HOME" /> 
    </condition> 

    <!-- The project.properties file is created and updated by the 'android' 
     tool, as well as ADT. 

     This contains project specific properties such as project target, and library 
     dependencies. Lower level build properties are stored in ant.properties 
     (or in .classpath for Eclipse projects). 

     This file is an integral part of the build system for your 
     application and should be checked into Version Control Systems. --> 
    <loadproperties srcFile="project.properties" /> 

    <!-- quick check on sdk.dir --> 
    <fail 
      message="sdk.dir is missing. Make sure to generate local.properties using 'android update project' or to inject it through the ANDROID_HOME environment variable." 
      unless="sdk.dir" 
    /> 

    <!-- 
     Import per project custom build rules if present at the root of the project. 
     This is the place to put custom intermediary targets such as: 
      -pre-build 
      -pre-compile 
      -post-compile (This is typically used for code obfuscation. 
          Compiled code location: ${out.classes.absolute.dir} 
          If this is not done in place, override ${out.dex.input.absolute.dir}) 
      -post-package 
      -post-build 
      -pre-clean 
    --> 
    <import file="custom_rules.xml" optional="true" /> 

    <!-- Import the actual build file. 

     To customize existing targets, there are two options: 
     - Customize only one target: 
      - copy/paste the target into this file, *before* the 
       <import> task. 
      - customize it to your needs. 
     - Customize the whole content of build.xml 
      - copy/paste the content of the rules files (minus the top node) 
       into this file, replacing the <import> task. 
      - customize to your needs. 

     *********************** 
     ****** IMPORTANT ****** 
     *********************** 
     In all cases you must update the value of version-tag below to read 'custom' instead of an integer, 
     in order to avoid having your file be overridden by tools such as "android update project" 
    --> 
    <!-- version-tag: 1 --> 
    <import file="${sdk.dir}/tools/ant/build.xml" /> 

</project>

我認爲財產上指向「SRC」文件夾source.dir這應該在您的構建文件結尾導入的android build.xml中定義。您可以通過將source.dir=test行添加到文件ant.properties（如在行<property file="ant.properties" />上方的註釋中提及）來覆蓋它。
