-aspectpath of external library(post compile weaving)

[Kirill614]

Hello, i am using io.freefair.aspectj.post-compile-weaving. When i have aspectj directory (with the aspect class) in root of my project - everything ok, but i need weave aspect from external library with my project sources, so i have this build.gradle file :

plugins {
    id 'java'
    id 'org.springframework.boot' version '2.6.3'
    id 'io.spring.dependency-management' version '1.1.4'
    id "io.freefair.aspectj.post-compile-weaving" version "8.6"
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'

java {
    sourceCompatibility = '16'
    targetCompatibility = '16'
}

configurations {
    aspect
}

repositories {
    maven {
        url = uri("https://plugins.gradle.org/m2/")
    }
    mavenCentral()
    mavenLocal()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter'
    aspect 'ru.vtb.smeg.lib:log-masker:1.3.1'
}

tasks.named('test') {
    useJUnitPlatform()
}

aspect 'ru.vtb.smeg.lib:log-masker:1.3.1' - its my external library which contains aspect class and all nesessary dependencies like aspectjrt, aspectjtools, aspectweaver. But when i build my project, i have this error:

java.lang.RuntimeException: Problem processing attributes in org/aspectj/ajdt/internal/compiler/CompilerAdapter.class

So how can i compile and weave aspect from external library taking into account that i need post compile weaving?

Your gradle configuration looks good to me. (Manually creating the aspect Configuration should not be necessary, but it should not hurt either)

Could you run the build with --info?
With which aspectj version was the aspect compiled?

[Lu-Whale]

I encountered the same issue. Did you solve it?

[atavanamir]

I have the same error after upgrade to v8.11

[larsgrefer]

Can someone of you provide an example project which I can use to debug this?

[pavelchuchma]

Reproduced on the latest versions: aspectj:1.9.22.1 and gradle plugin v8.11

It is enough to have aspectjtools library on aspectpath (in aspect gradle configuration)

like this:

aspect 'org.aspectj:aspectjtools:1.9.22.1'

I believe that ru.vtb.smeg.lib:log-masker:1.3.1 from the original description depends on aspectjtools lib.

I'm not sure if it is bug in user's lib or aspectj, it's up to you.

[larsgrefer]

I was able to reproduce it. Apparently, the AspectJ compiler does not like it, if you feed itself into its aspectpath.

On the one hand, I'd argue that it makes no sense to have aspectjtools.jar on the aspectpath or as an dependency of an aspect.

But on the other hand, it's a bug in AspectJ to fail - this spectacularly - on this.

An aspect only needs to depend on aspectjrt, but not on aspectjtools or aspectweaver.

I'd suggest removing aspectjtools from the aspect path
