*(Includes solution)* I was having this weird issue where when I use a Spark 0.9.1 or earlier Jar file in IntelliJ I can see its contents and IntelliJ can work with it. But when I compile version 1.0.0 from source my jar is not being recognized by IntelliJ even though I can build my project using ant from the command line.
*Snapshot attached.* [image: Inline image 1] Basically IntelliJ on Mac always uses Apple JDK 1.6 to run. You have to manually change it to run under 1.7 so it can look inside a 1.7 jar compiled to 1.7 byte code. In case you run into this, use this link to change the JVM under which intelliJ runs. https://intellij-support.jetbrains.com/entries/23455956-Selecting-the-JDK-version-the-IDE-will-run-under
