Re: [aspectj-users] An internal error occurred during: "Computing additi

["Alexander Kriegisch" <alexander@xxxxxxxxxxxxxx>]

Mikael, I am hosting the aspectj.dev update site on my private shared hosting webspace, being the owner of the domain. I never experienced that problem you report and can download the file it complains about by clicking on the link. Sometimes I see GitHub CI builds fail due to temporary glitches in site availability when using dependencies hosted on aspectj.dev. It seems as if my ISP is not doing the very best job there. Can you just try again? I think that should suffice. Eclipse or AJDT should not access sites when running, only when updating.

With regard to Eclipse support, I think the two add-ons discussed here should still work. They do for me, at least. As much as I love IntelliJ IDEA, they are also neglecting AspectJ, so it is not a perfect solution either. But it is working, also in connection with Maven. Syntax highlighting, intelli-sense and some native syntax features could use improvement, though. Also, IDEA sometimes complains about native AspectJ pointcut types used in Spring projects, because despite compiling and running the code just fine, the editor seems to assume that when using Spring, the AOP tool used is always Spring AOP, which only supports a subset of AspectJ features.

I think, as long as your leading system is Maven and you use either the dev.aspectj variant of aspectj-maven-pluging - recommended with a bias, because I am maintaining it, but also because it has more features than the Mohjohaus version - or, if sufficient for you, the Mojohaus version, and Maven import in Eclipse and IDEA is still working, you should have no reason to despair or even give up on AspectJ.

Cheers
