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，这样我就可以解决我在Android SDK中遇到的编译时问题，以及图书馆导入和管理的简易性。我遇到的问题是：

1）如何修改build.xml以指示它使用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

所以我认为我必须修改ant.properties属性，我怎么建议使用Maven？

这是我在项目的Parent目录中粘贴的POM.xml，但是当我尝试运行mvn compile时，出现以下错误：

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:
[ERROR]

[ERROR] ....This might be a side-effect of a migration to Android Maven Plugin 4+.

最后，这是POM.xml：

                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

那我在这里做错了什么？你能帮忙的话，我会很高兴。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。

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