問題描述

我正在嘗試在我的項目中使用 java 8，為此我添加了 jack 編譯器.

I'm trying to use java 8 in my project and for that I added the jack compiler.

啟用杰克后，我開始遇到使用注釋處理的庫的問題，并在網上查看我讀到我需要 android studio 2.2 和 com.android.tools.build:gradle:2.2.0-alpha6 來編譯生成的庫注釋中的代碼.

After enabling jack I started having problems with libraries that use Annotation Processing and looking in the web I read that I need android studio 2.2 and com.android.tools.build:gradle:2.2.0-alpha6 to compile libraries that generate code from annotations.

我下載了 Android Studio 2.2 preview 6 并將我的項目轉換為它.之后我發現不再支持 apt gradle 插件，然后我需要將每個使用 apt 的依賴項更改為使用新的 annotationProcessor 選項.

I download Android Studio 2.2 preview 6 and converted my project to it. And after that I discovered that the apt gradle plugin is not supported anymore and then I needed to change every dependency that use apt to the use the new annotationProcessor option.

例如:

apt "org.projectlombok:lombok:$rootProject.lombokVersion"

到

annotationProcessor "org.projectlombok:lombok:$rootProject.lombokVersion"

現在，如果我使用make project"，項目編譯沒有問題，但如果我嘗試執行它，我應該由注釋生成的代碼出現錯誤.

Now if I use "make project" the project is compiled without problems, but if I try to execute it I have errors with the code that should be generated by the annotations.

此外，當我打開項目時，我收到來自 lombok 插件的警告項目的注釋處理似乎已禁用".當我打開項目設置并轉到構建 -> 編譯器"時，我找不到注釋處理器.

Also when I open the project I receive a warning from the lombok plugin "Annotation processing seems to be disabled for the project". When I open the project settings and go to "Build -> Compiler" I can't find Annotation Processors.

所以，我的問題是:如何在 Android Studio 2.2 中啟用注釋處理器?這個功能被禁用了?如果是，如何從注解生成代碼?

So, my question is: How can I enable Annotation Processors in Android Studio 2.2? This feature was disabled? If yes, how can I generate the code from annotations?

--編輯--我正在制作一個 PullRequest 來更改項目以使用 Java8 編譯，您可以在此處查看 PR:https://github.com/jonathanrz/myexpenses-android/pull/57

--EDIT-- I'm making a PullRequest to change the project to compile with Java8, you can check the PR here: https://github.com/jonathanrz/myexpenses-android/pull/57

推薦答案

關閉項目.在Welcome to Android Studio"對話框中點擊右下角的Configure".

Close the project. In the "Welcome to Android Studio" dialog click "Configure" in the bottom right corner.

那么，

設置 > 構建、執行、部署 > 編譯器 > 注釋處理器.勾選啟用注釋處理".

Settings > Build, Execution, Deployment > Compiler > Annotation Processors. Tick 'Enable annotation processing'.

如果這不起作用.從Welcome to Android Studio"對話框中刪除項目并從新打開.

If that does not work. Delete the project from "Welcome to Android Studio" dialog and open from new.

為我工作.
