I have spring framework dependencies in my Maven project. I want to attach the Javadoc for spring framework dependencies.
I added to pom.xml following lines
<repositories>
    <repository>
        <id>springsource-repo</id>
        <name>SpringSource Repository</name>
        <url>http://repo.springsource.org/release</url>
    </repository>
</repositories>
<build>
<plugins>
    ...
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-eclipse-plugin</artifactId>
        <version>2.9</version>
        <configuration>
            <downloadSources>true</downloadSources>
            <downloadJavadocs>true</downloadJavadocs>
        </configuration>
    </plugin>
</plugins>
</build>
I have installed m2eclipse and I also checked option Download Artifact Sources/Javadoc in settings.
When I run mvn eclipse:eclipse, it doesn't show any warnings. But javadoc .jar files aren't downloaded.
