android – 在Eclipse中转换为Maven项会导致ClassNotFoundException

新创建时,简单的Android应用程序运行正常.但是,当我将其转换为Maven项目时,每当我尝试运行应用程序时,我都会开始获取ClassnotFoundException.我已经尝试更新项目,重新启动Eclipse,检查构建路径中的所有库,清理和重建项目,重新启动模拟器,并将我的pom.xml减少到最低限度.

这个错误的原因是什么？对Maven来说是一些简单的错误配置吗？

我的MainActivity.java：

package com.example.myproject;

import android.os.bundle;
import android.app.Activity;
import android.view.Menu;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceStatE) {
        super.onCreate(savedInstanceStatE);
        setContentView(R.layout.activity_main);
    }

    @Override
    public Boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main,menu);
        return true;
    }

}

更新：我发现在pom.xml上尝试做Maven Clean和Maven生成源成功.但是,Maven安装给我一个错误：

[ERROR] COMPILATION ERROR : 
[INFO] -------------------------------------------------------------
[ERROR] MainActivity.java:[12,33] package R does not exist
[ERROR] MainActivity.java:[18,44] package R does not exist

我还在最新的编辑中添加了一些内容(依赖和包装)以及修改过的(1.6-> 1.7,3.1-> 3.0)pom.xml文件.
