Scala – Android App构建失败

我按照说明为Android构建Scala应用程序：
scala-to-android

基本上,我安装了Scala并将ant build.properties更改为指向Scala并将build.xml更改为包含build-scala.xml.

ant scala-compile 

是成功的,但是,

ant debug

生成以下构建错误：

Scala的编译：

-shrink-if-test:
     [echo] Checking if Scala libraries are installed on emulator or device...
      [adb] bootclasspath=/system/framework/core.jar:/system/framework/ext.jar:/system/framework/framework.jar:/system/framework/android.policy.jar:/system/framework/services.jar

-shrink-config:
  [taskdef] Could not load deFinitions from resource scala/tools/ant/task.properties. It Could not be found.

BUILD Failed
/home/salil/Programs/android-projects/FirstScala/build-scala.xml:82: Problem: Failed to create task or type invoked
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.

我是ant,Android和Scala的初学者.任何帮助,将不胜感激.非常感谢提前！

解决方法:

我在Scala上遇到了与android dev相同的问题.实际上,构建脚本会查找名为task.properties的文件,该文件位于scala / tools / ant / task.properties中.这包装在jar ant-invoked.jar中.我希望你能从该网站下载android-sdk项目zip存档.只需将android-sdk根目录下的“configs”文件夹复制到项目根文件夹中即可.
这是在scala-build.xml中搜索文件的

<!-- Project settings -->
property name="configs.dir" value="${basedir}/configs" />
<property name="ant-invoked.jar" value="${configs.dir}/ant/ant-invoked.jar" />

和目标shrink-config

<target name="-shrink-config"
        description="Generate ProGuard configuration file">
    <taskdef resource="scala/tools/ant/task.properties"
             classpath="${ant-invoked.jar}" />
