IntelliA中的AndroidAnnotations处理失败，因为未生成R.java
我认为IntelliJ在生成R.java文件时存在一些问题，导致AndroidAnnotations出现问题，因为它无法解析布局的资源ID。
这是我的活动：
package com.airlocksoftware.canvastest;
import android.app.Activity;
import android.os.Bundle;
import com.googlecode.androidannotations.annotations.EActivity;
@EActivity(R.layout.main)
public class MyActivity extends Activity {
/**
* Called when the activity is first created.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
}
奇怪的是，即使我注释掉注释并执行setContentView(R.layout.main)，即使从未导入R.java，它也能正常工作。
顺便说一下，布局只是一个简单的“Hello World”。没有什么奇怪的事情发生在那里。
无论我做什么，我都无法获得AndroidAnnotations来生成CanvasActivity_.java。我的pom.xml看起来像这样：
<?xml version="1.0" encoding="UTF-8"?>

注释处理set up like shown in this screenshot.
基本上我将处理器路径设置为指向本地maven仓库中的jar文件，为described here.
项目来源设置为like shown in this screenshot.
无论我如何制作/重建项目，gen / aa中都没有出现任何内容（因此我无法引用CanvasActivity_.java）我从项目根目录运行了mvn clean install，这与此stacktrace失败。< / p>

老实说，我现在不知所措。如果有人知道该怎么做，那将是惊人的。谢谢！
编辑：这是IntelliJ生成的存根R.java。
/*___Generated_by_IDEA___*/
package com.airlocksoftware.canvastest;
/* This stub is for using by IDE only. It is NOT the R class actually packed into APK */
public final class R {
}

因为您的pom.xml缺少以下内容：
<packaging>apk</packaging>
如果不这样，R.java文件将不会生成。
将其添加到pom.xml的顶部，如下所示：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.airlocksoftware.canvastest</groupId>
<artifactId>CanvasTest</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>apk</packaging>
/* ... */
/* rest are fine */
/* ... */

这很奇怪。你maven配置似乎很棒。它至少应该通过Maven编译好...... 我不认为这是因为错误应该是不同的，但你是否更新到最后一个Android SDK 22？
