使用ant編譯java代碼

Question

我對使用ant有點新，目前，我製作ant腳本的方式是通過eclipse自動生成它們以生成可運行jar。問題在於它只能讀取bin目錄。因此，如果我要更改一個java src文件，我不會看到在ant build中複製的更改。我需要添加到我的螞蟻腳本？我下面所示的一個示例腳本：

<?xml version="1.0" encoding="UTF-8" standalone="no"?> 
    <project default="create_run_jar" name="Create Runnable Jar for Project poodah"> 
    <!--this file was created by Eclipse Runnable JAR Export Wizard--> 
    <!--ANT 1.7 is required          --> 
    <target name="create_run_jar"> 
     <jar destfile="../lib/TestMaster.jar" filesetmanifest="mergewithoutmain"> 
      <manifest> 
       <attribute name="Main-Class" value="test.startup.TestMaster"/> 
       <attribute name="Class-Path" value="."/> 
      </manifest> 
      <fileset dir="../test/bin"/> 
     </jar> 
    </target> 
    </project> 

我嘗試閱讀一些文件，但它是一個有點混亂。

您需要的javac螞蟻的任務

編譯你的源代碼假設你的項目結構是：

java 
    your 
    package 
     structure 
     SomeClass.java 
lib 
    log4j.jar 
    guava-14.jar 
test 
    bin 

<?xml version="1.0" encoding="UTF-8" standalone="no"?> 
<project default="create_run_jar" name="Create Runnable Jar for Project poodah"> 
    <!--this file was created by Eclipse Runnable JAR Export Wizard--> 
    <!--ANT 1.7 is required          --> 
    <target name="create_run_jar" depends="compile"> 
     <jar destfile="../lib/TestMaster.jar" filesetmanifest="mergewithoutmain"> 
      <manifest> 
       <attribute name="Main-Class" value="test.startup.TestMaster"/> 
       <attribute name="Class-Path" value="."/> 
      </manifest> 
      <fileset dir="../test/bin"/> 
     </jar> 
    </target> 

    <target name="compile"> 
    <javac srcdir="java" destdir="../test/bin" includes="**/*.java" target="1.6"> 

     <classpath refid="classpath.base" /> 
    </javac> 

    </target> 
    <!-- Libraries on which your code depends --> 
    <path id="classpath.base">                               
    <fileset dir="lib">                               
     <include name="**/*.jar" />                           
    </fileset>                                 
    </path> 
</project> 

Answer 2

添加你的編譯目標的依賴

<target name="create_run_jar" depends="compile"> 
    <jar destfile="../lib/TestMaster.jar" filesetmanifest="mergewithoutmain"> 
     <manifest> 
      <attribute name="Main-Class" value="test.startup.TestMaster"/> 
      <attribute name="Class-Path" value="."/> 
     </manifest> 
     <fileset dir="../test/bin"/> 
    </jar> 
</target> 
</project> 

compile目標

<target name="compile" depends="" description="compile the java source files"> 
<javac srcdir="." destdir="../test/bin"> 
    <classpath> 
     <fileset dir="${lib}"> 
      <include name="**/*.jar" /> 
     </fileset> 
     </classpath> 
</javac> 

Answer 3

你需要一個<javac>任務添加到您的Ant腳本。
