Where is javax.annotation

Question

Ok, so this is probably a NooB question (I'm more of a C++ guy), but I'm lost in the java woods and its frameworks forests...

I'm trying to look into eclipse RCP development. For that I'm following this well-known tutorial: http://www.vogella.com/tutorials/EclipseRCP/article.html

At step 15 I need to add the following dependency packages to import in my bundle. javax.annotation javax.injection

The problem is that I cannot select these (they are not in the selection list) I do have javax.el javax.servlet.* and javax.xml.*

Looking at http://docs.oracle.com/javase/7/docs/api/overview-summary.html suggests that this should be part of the standard java.

What obvious mistake am I missing?

Answer 1

The dependency including version:

<dependency>     <groupId>javax.annotation</groupId>     <artifactId>javax.annotation-api</artifactId>     <version>1.3.2</version> </dependency> 

See: http://mvnrepository.com/artifact/javax.annotation/javax.annotation-api

Or for the newerjakarta.annotation:

<dependency>    <groupId>jakarta.annotation</groupId>    <artifactId>jakarta.annotation-api</artifactId>    <version>1.3.5</version> </dependency> 

See: https://mvnrepository.com/artifact/jakarta.annotation/jakarta.annotation-api

The Java Common Annotations Module java.xml.ws.annotation was deprecated in Java version 9 and was removed in java version 11. If this leads to a problem you could try to add javax.annotation.

The Javadocs for Java 8 can be found here: http://docs.oracle.com/javase/8/docs/api/javax/annotation/package-summary.html

Your comment indicates this is for Guava, so you want the JSR305 library, which extends the javax package.

2020 Update: Note that this library breaks the Oracle licensing agreement and Guava has since moved to checkerframework's Nullable annotation.
