I could not for the life of me get the patch created by @fbis251 to work. Nevertheless, the very simple solution noted is correct. But all you need to do is edit the PKGBUILD to remove "build-on-linux.patch" entirely, and replace the patch line in prepare() with:
sed -i 's/targetCompatibility\ \=\ 1\.7/targetCompatibility\ \=\ 1\.8/g' build.gradle
And that's it. With that one very simple change, it compiles successfully for me.

This package builds the raccoon software from source. Since the mainainer is in the process of abandoning Github (see [0] for reasons) and the sources are not available otherwise yet, this package will sit at the last released version published on Github, until new sources are available. If you wish to use the more recent versions of the program instead of waiting for the sources to be released, you can use raccoon-bin [1] as a workaround for now.
Please don't flag this package out-of-date, unless new source versions are available. Thank you for your understanding.
