我認爲IntelliJ在生成R.java文件時存在一些問題，這導致了AndroidAnnotations中的問題，因爲它無法解析我的資源ID佈局。AndroidAnnotations處理在IntelliJ中失敗，因爲沒有生成R.java
這裏是我的活動：
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);
}
}
什麼奇怪的是，即使我註釋掉的註釋，並做setContentView(R.layout.main)，它工作得很好，即使R.java從未進口。
順便說一句，佈局只是一個簡單的「你好世界」。沒有什麼奇怪的去那裏。
無論我做什麼，我都無法使AndroidAnnotations生成CanvasActivity_.java。我的pom.xml看起來是這樣的：

註釋處理set up like shown in this screenshot.
基本上我安裝的處理器路徑指向我的本地Maven回購的jar文件，爲described here.
項目來源設置like shown in this screenshot.
無論我如何創建/重建項目，gen/aa中都沒有顯示出來（因此我無法引用CanvasActivity_.java）我從項目根目錄運行了mvn clean install，該堆棧跟蹤失敗。

老實說我現在處於虧損狀態。如果有人知道該怎麼做，那會很棒。謝謝！
編輯：這裏是由IntelliJ生成的stub 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 {
}
好的，真棒。現在它正在使用maven從命令行正確構建。但IntelliJ仍然沒有運行註釋處理，所以生成的文件永遠不會像gen/aa那樣最終結束。有任何想法嗎？ – liftdeadtrees
Hi @ liftdeadtrees，是的IntelliJ的IDE編譯器正在進行中，我有很多問題，它正確地檢測註釋。大多數情況下，我必須按照屏幕截圖中指定的方式編輯「Annotation Processors」，並且必須將*完整路徑*賦予JAR，而不是相對路徑。嘗試還檢查「從項目類路徑獲得處理器」，看看是否有效...... – Subhas
我甚至不知道這是你的意思，但我把路徑從〜/ .m2/rest/of /路徑/Users/matthewbbishop/.m2/rest/of/path，現在出於一些非常奇怪的原因，它的工作。我非常感謝你的幫助。 – liftdeadtrees
