I just downloaded Eclipse on my Mac after a good six months without needing it and had numerous issues using it. First, it wouldn’t start and gave the error message below.

I realised that the openjdk 1.7.0 package I’d installed must be somehow overriding or interfering with the 1.6.0 JDK that Apple installs by default. So I went into
Applications > Utilities > Java Preferences
. As soon as I opened that I was prompted by a message that said that in order to open Java Preferences I must install a Java 6 runtime and asked me if I would like to do so. I obviously said yes after which I reviewed the order of JDKs in Java Preferences which was correct.The IBM Development Package for Eclipse.

Next, as I created a Java project, I realised Eclipse was still operating with a JRE and unsurprisingly I couldn’t access the source code of the JDK libraries. To resolve both these issues at once I went into
Eclipse > Preferences > Java > Installed JREs > Add
and added the following path.![Jdk for eclipse machine Jdk for eclipse machine](/uploads/1/3/4/8/134826507/335744887.jpg)
You’ll notice this path contains the essential src.jar. Then I went into
Project > Properties > Java Build Path > Libraries
, removed the existing JRE and added the new JDK. I was now able to open String.class and see the source and all was well.Jdk For Eclipse Machine
Why is Java still such a nightmare on OS X after all this time? I really hope it improves with Java 8. Anyway, I wrote all this up in the hope that it helps others also struggling with such problems.
