问题
I added twitter4j 3.0.3, into an Eclipse project but it does not import any classes from the jar. I copied in some code samples from the twitter4j jar files but eclipse can't find any of the classes in those files - e.g. Twitter, ConfigurationBuilder, TwitterFactory etc... I've added twitter4j-core-3.0.3-sources.jar to my build path. But Eclipse doesn't suggest to import any classes in these files. Is there anything I'm missing?
回答1:
You need to add the twitter4j-core-3.0.3.jar JAR to your build path, it can be found under the lib directory of the download.
The twitter4j-core-3.0.3-sources.jar JAR only contains source code.
