Maven:将Android项目从Ant迁移到Maven

Question

我启动了一个Android项目，默认情况下它是用ANT构建的，我正在尝试将其升级到Maven，这样我就可以摆脱Android SDK的编译时问题，以及库导入和管理的方便性。我遇到的问题是：

1( 如何修改build.xml以指示其使用maven。2( Maven抱怨文件夹结构错误。

这是我的build.xml：

<?xml version="1.0" encoding="UTF-8"?>
<project name="myapp" 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>
// and more

所以我想我必须修改ant.properties属性，我该如何建议使用Maven？？

这是我粘贴在项目的Parent目录中的POM.xml，但当我尝试运行mvn-compile时，我得到了以下错误：

Failed to execute goal com.jayway.maven.plugins.android.generation2:android-maven-plugin:4.0.0-rc.2:generate-sources (default-generate-sources) on project gs-maven-android:

最后，这里是POM.xml：

</project>

那么我在这里做错了什么？任何帮助都会很好。我在Ubuntu Linux上使用Intellij Idea。谢谢

请更新到完整版本，然后更新帖子中的错误消息。最新版本是4.3.0。

该警告是关于位于非标准文件夹中的源代码和其他源的。您应该使用标准结构。完整版本将显示错误消息，其中包含所有内容的详细信息。
