Question

我有一个使用外部jar的库。（Unity的东西）我怎么能再次链接它以便ant jar命令成功？我对蚂蚁很陌生，所以我有点失落......

我尝试添加新属性：

<property name="unity.androidplayer.jarfile" value="/Applications/Unity/Unity.app/Contents/PlaybackEngines/AndroidDevelopmentPlayer/bin/"/>
    <path id="classpath">
        <fileset dir="${unity.androidplayer.jarfile}" includes="**/*.jar"/>
    </path>

然后添加“编译”目标

<target name="compile"
        description="Compiles project's .java files into .class files">
  <javac encoding="ascii" debug="true">
    <src path="${source.dir}" />
    <classpath>
      <pathelement location="${sdk.dir}\platforms\${target}\android.jar"/>
      <pathelement location="${unity.androidplayer.jarfile}"/>
    </classpath>
  </javac>
</target>

但更糟糕的是，我得到更多错误:(

我还在jar目标中尝试了<zipgroupfileset dir="${unity.androidplayer.jarfile}" includes="*.jar" excludes="*.config"/>，但没有任何改变。

我认为我没有将${unity.androidplayer.jarfile}添加到正确的位置。

最初我的build.xml 看起来像这样，现在我将库中的符号添加到libs /中，我认为这不是最佳解决方案。

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

<property file="local.properties" />
<property file="ant.properties" />
<property environment="env" />
<condition property="sdk.dir" value="${env.ANDROID_HOME}">
    <isset property="env.ANDROID_HOME" />
</condition>

<loadproperties srcFile="project.properties" />

<fail
        message="sdk.dir is missing. Make sure blah blah..."
        unless="sdk.dir"
/>

<!-- Jar target to make it a library -->
<target name="jar" depends="debug">
  <jar
      destfile="bin/MySuperLibrary.jar"
      basedir="bin/classes"
      includes="net/mycompany/myapp/*"
      />
</target>

<import file="custom_rules.xml" optional="true" />

<import file="${sdk.dir}/tools/ant/build.xml" />

非常感谢任何帮助

日志表明问题与javac无法在指定的类路径中找到库有关。我会在我的构建文件中尝试使用类似的东西。

  <path id="android">
    <fileset dir="${sdk.dir}\platforms\${target}">
      <include name="*.jar"/>
    </fileset>
  </path>

  <path id="unity">
    <fileset dir="${unity.androidplayer.jarfile}">
      <include name="*.jar"/>
    </fileset>
  </path>

...

  <javac encoding="ascii" debug="true">
    <src path="${source.dir}" />
    <classpath>
        <path refid="android"/>
        <path refid="unity"/>
    </classpath>
  </javac>

如何链接Ant中的外部jar？
