Compilation failures

I'm getting the following trying to build tivolibre:

./net/straylightlabs/tivolibre/PyTivoMetadata.java:300: error: illegal start of expression
            list.stream().forEach(e -> writer.format("%s : %s%n", field, e));

It looks like it's failing on the new stream API from Java 8. Can you confirm the version of Java you're using is 1.8.0 or higher?

[opoplawski]

Yeah, this is 1.8.0.

[opoplawski]

Also get it with 1.7.0 though.

[fflewddur]

You'll definitely get it with 1.7, because lambdas were only added in Java 8 :)

Could you verify that your JDK is setup to use 1.8 as the Java compiler, and not just the runtime? The output of javac -version should be something like 1.8.0_66.

The current codebase compiles for me on Oracle's latest Java VM on Mac OS X 10.11.1, Windows 7 SP1, and Windows 10. Each platform build works both from within IntelliJ and using an external Ant build file, so I'm pretty certain there isn't a syntax error in the code.

[opoplawski]

Ah, I found the issue. I was assuming that openjdk 1.8.0 overrode 1.7.0 in EL7, but it doesn't. Sorry for the noise.

Cool, glad to hear you got it working!
