android - 移动到 Android Annotations v.2.7 后的 java.lang.ArrayStoreException : sun. reflect.annotation.TypeNotPresentExceptionProxy

Question

在迁移到 Android Annotations v.2.7 后，我在 eclipse 中构建我的项目时遇到了问题，同时 maven build 没问题。这是来自 Eclipse 错误日志的堆栈跟踪:

Error

Answer 1

在 @pyricau 的帮助下我解决了问题。这是他对 issue tracker 的回应:

As far as I can see, AbstractProcessor.getSupportedSourceVersion() tries to read the @SupportedSourceVersion annotation on the processor.

From the stacktrace, we can deduce that the AnnotationParser is trying to read all the annotations on the processor class. And that one of these annotations has a class array parameter that contains classes that cannot be loaded.

The only annotation that has a class array in AndroidAnnotationsProcessor is @ SupportedAnnotationClasses.

From that we can deduce that the annotations supported by androidannotations are not present, which means they are not in the classpath of the eclipse compiler.

As you probably noted, we extracted the API jar as a separate Maven artifact, leading to a new maven configuration:

<dependencies>
        <!-- [...] -->
    <dependency>
        <groupId>com.googlecode.androidannotations</groupId>
        <artifactId>androidannotations</artifactId>
        <version>2.7</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>com.googlecode.androidannotations</groupId>
        <artifactId>androidannotations-api</artifactId>
        <version>2.7</version>
    </dependency>
</dependencies>

Since you are telling me that is works fine with Maven, I assume you configured this right.

Previously, the androidannotations dependency contained the annotations. It doesn't contain them any more, they are now in the androidannotations-api jar.

This is fine for Maven, because dependencies available in scope compile are also available to Javac. However, Eclipse differentiate those dependencies with the annotation processing jars.

So, I assume that you're using the "manual way" to configure the eclipse annotation processing: adding jars to Java Compiler > Annotation Processing > Factory Path. And it currently only contains androidannotations-2.7.jar.

To fix the problem, you should add the two AndroidAnnotations dependencies: codemodel and androidannotations-api

Here is how we should update the doc: (SOLUTION!)

1. Right-click your project, choose Properties
2. Go to Java Compiler > Annotation Processing and choose Enable annotation processing
3. Go to Java Compiler > Annotation Processing > Factory Path
4. Click on Add Variable, select M2_REPO and click on Extend...; then, select the following JAR : com/googlecode/androidannotations/androidannotations-api/2.7/androidannotations-api-2.7.jar
5. Click on Add Variable, select M2_REPO and click on Extend...; then, select the following JAR : com/sun/codemodel/codemodel/2.4.1/codemodel-2.4.1.jar
6. Click on Add Variable, select M2_REPO and click on Extend...; then, select the following JAR : com/googlecode/androidannotations/androidannotations/2.7/androidannotations-2.7.jar
7. Confirm the workspace rebuild
8. Done!
