| 43 | +Weaving Java Binaries |
| 44 | + |
| 45 | + {{{http://en.wikipedia.org/wiki/Aspect_weaver}Aspect weaving}} is a process |
| 46 | + of modifying binary <<<.class>>> files after compilation in order |
| 47 | + to inject AOP advice at certain join points. |
| 48 | + |
| 49 | + First of all, you annotate your classes and methods, and then compile. Then |
| 50 | + you run AspectJ weaver which modifies <<<.class>>> files, producing |
| 51 | + new "weaved" versions of them. |
| 52 | + |
| 53 | + Luckily, these steps can be automated. |
| 54 | + All you need to do to start using our AOP aspects is |
| 55 | + add these two artifacts to your <<<build.gradle.kts>>>: |
| 56 | + |
| 57 | ++-- |
| 58 | +dependencies { |
| 59 | + implementation("com.jcabi:jcabi-aspects:${latestVersion}") |
| 60 | +} |
| 61 | ++-- |
| 62 | + |
| 63 | + Then, you use |
| 64 | + {{{https://plugins.gradle.org/plugin/io.freefair.aspectj.post-compile-weaving}post-compile-weaving}} |
| 65 | + plugin which executes AspectJ weaver to modify your <<<.class>>> files: |
| 66 | + |
| 67 | ++-- |
| 68 | +plugins { |
| 69 | + id("io.freefair.aspectj.post-compile-weaving") version "${latestVersion}" |
| 70 | +} |
| 71 | + |
| 72 | +dependencies { |
| 73 | + implementation("com.jcabi:jcabi-aspects:${latestVersion}") |
| 74 | + aspect("com.jcabi:jcabi-aspects:${latestVersion}") |
| 75 | +} |
| 76 | ++-- |
| 77 | + Also, don't forget to mark jcabi dependency as <<<aspect>>> |
| 78 | + |
| 79 | + {{{./example-weaving-eclipse.html}Additional configuration for eclipse |
| 80 | + users}}. |
| 81 | + |
| 82 | + That's it. {{{https://www.l3r8y.ru/2024/01/15/how-to-use-jcabi-aspects-with-gradle}Link to original post}}. |
