Unsupported major.minor version about jnativehook

[kwhat]

Its compiled for a later version of Java than you have available. IIRC I moved the target byte code version to 1.7 because Java 1.6 is end of life. Unless there is a good reason to keep Java 6, you should upgrade to at least version 1.7. If you can't for whatever reason, just recompile the class files in the library for Java 6 and repackage the jar. If you need help doing that let me know.

Will I be able to compile it for 1.5 as well? I don't want to rely on users being up to date and want to be backward-compatible as far as possible. :)

@kwhat Hey, thanks for making this library. I have to use Java 6 because version 7 on Mac is 64-bit only and I need to write a plugin for a 32-bit application.
Could you help me with the recompilation and the repackaging?
I've downloaded the OSX java 6 version, added it to the installed JREs section in Eclipse, imported JNativeHook to Eclipse, set it's Java System Library to the 1.6, set the compliance to 1.6. I then exported a jar, unzipped it and added the native binaries and manifest from the original jar you provided and rezipped it...still get the same version error. What else do I need to do?

Thanks

If there is still demand for 1.5, 1.6 I will build the next RC for 1.5 target. To recompile to class files yourself, extract the jar and place the content of the org/jnativehook/lib folder in the projects root so that you have ./lib and ./src in the same location. Then you should be able to run ant -Dant.build.javac.source=1.5 -Dant.build.javac.target=1.5 compile-java jar and get a new jar built for 1.5 will all of the native binaries packaged back in.

We need to have the jdk 1.5 installed to compile it for 1.5, don't we?

I get the following error when running your command:

build.xml:168: Could not load definitions from resource org/jnitasks/antlib.xml. It could not be found.

Total time: 0 seconds

Also, do you have a release date for RC3?

[kwhat]

You do not need a 1.5 JDK, however 1.8 may cause some issues. (I haven't tested building with 1.8) Javac will probably warn about the bootclasspath when trying to compile for 1.5, you can fix that by adding -Dant.build.javac.args="-bootclasspath /path/to/jre/lib/rt.jar" where /path/to/jre/lib/rt.jar points to the lib/rt.jar file of the jre you are using. It may be located under the jdk folder you installed to.

As far as the RC3 release date, I just need to do some testing with fabricating native events and make sure that code is complete and review a pull request. Hopefully this weekend.

I still cannot compile, as the mentioned antlib.xml is missing in the sources..

Great! If we cannot get it to compile on my setup, I might just wait for your new RC :)

[kwhat]

Put the jnitasks.jar in the jar folder as par the instructions ;)

Had no time until today to test it. But it works fine now, thank you very much! :)
