QUESTION
ANSWER
Answered 2021-May-07 at 13:09OK, you are using this example from the plugin source code repository. Why didn't you just say so and link to it? You made it look as if you created the sample by yourself. I found it and also the project/plugins.sbt
which you did not post here. Like I told you before in our chat, I am a Scala noob, I never used it in my whole life and had no idea that a file was missing. That cost me a lot of time. Why did you post an incomplete sample project here instead of publishing it on GitHub like I asked you to? Then I could just have cloned the project and run it. Not until I found the sample code online, did I realise that yours was incomplete.
Furthermore, my IDE IntelliJ IDEA cannot import the sample project, there must be some kind of bug in the current version. I can only compile and run from sbt shell. There, I could finally reproduce your problem.
Actually, the explanation is quite simple: The plugin is outdated and ought to be updated ASAP. It depends on AspectJ Compiler Tools 1.8.10 which only supports Java 8. It is not even the most recent 1.8 release, that should be 1.8.13. Also, the plugin exports AspectJ Runtime 1.8.10 as a runtime dependency to projects using the plugin. See also:
- https://github.com/sbt/sbt-aspectj/blob/8ff3a1ad4224934dabe222205eb89c985670f240/build.sbt#L7
- https://github.com/sbt/sbt-aspectj/blob/8ff3a1ad4224934dabe222205eb89c985670f240/src/main/scala/com/lightbend/sbt/SbtAspectj.scala#L30
As long as you compile and run your project on JDK 1.8, everything is fine. If you use a more recent JDK, the solution is to override the dependencies. Put this into project/plugins.sbt

I can already retrieve the document and it shows in the console but how can I retrieve the individual fields so I can display it in the screen?
...ANSWER
Answered 2021-May-01 at 10:05There's no field named as uid
in the document. So please make sure you add it first else the 'where' query won't work as intended. You cannot fetch a single field from Firestore. First fetch the whole document and then use the relevant data.
QUESTION
I am trying to use the Aspectj compiler ajc in a modular (OSGi setting). The standard way ajc seems to be used is to take aspects & java code and turn it into one a JAR with all classes and resources in the -inpath
, -aspectpath
, and -sourceroots
.
I am trying to weave aspects an OSGi executable JAR from bnd. This executable jar contains a set of bundles that need to be woven. However, in a modular system, the boundary is quite important. For one, the manifest often contains highly relevant information to that bundle or one of the many extenders. Flattening all the classes into a big blog won't work.
I am therefore weaving each bundle separately. However, then the output is cluttered with the aspects. I'd like to import these to keep the aspect modules proper modules. However, using the annotation programming model, I notice that ajc is modifying the aspect modules, so I need to rewrite those as well. This is fine, but since I weave each bundle separately, I have the question if the weaving of the aspect could depend on what gets other modules woven? That is, does the modification of the annotated aspect depend on the classes that it is woven in?
The other issue is what happens to resources with the same name? Since my -inpath
is only one JAR (the bundle), I notice I end up with the correct manifest (META-INF/MANIFEST.MF) in the output. However, if the -inpath
consists of many bundles, what will the manifest be? Or any other resource that has the same path and thus overlaps?
Last issue is external dependencies. I understand acj wants to see the whole world and include this whole world into the output JAR. However, I must exclude external dependencies of a bundle. Is there a way to mark JARs as: use, but do not include. A bit like the maven 'provided' scope?
Summary:
- Does the modification of an @Aspect annotated class depend on the targets that is applied to?
- Can I compile the @Aspect annotated classes into separate JARs?
- How to handle the external dependencies that will be provided in the runtime and thus must be excluded from the output JAR.
- What are the rules around overlapping resource paths in the
-inpath
and-sourceroots
?
UPDATE In the mean time I've made an implementation in Bndtools.

Answered 2021-Mar-03 at 01:56Does the modification of an @Aspect annotated class depend on the targets that is applied to?
If you want to be 100% sure you have to read the AspectJ source code, but I would assume that an aspect's byte code is independent of its target classes, because otherwise you could not compile aspects separately and also not build aspect libraries.
Can I compile the @Aspect annotated classes into separate JARs?
Absolutely, see above.
How to handle the external dependencies that will be provided in the runtime and thus must be excluded from the output JAR.
If I understand the question correctly, you probably want to put them on the class path during compilation, not on the inpath.
What are the rules around overlapping resource paths in the
-inpath
and-sourceroots
?
Again, probably you have to look at the source code. If I was you I would simply assume that the selection order is undefined and make sure to not have duplicates in the first place. There should be Maven plugins helping you with filtering the way you want the result to be.
bndtools seems to have close ties to Eclipse. So does AspectJ as an Eclipse project. Maybe you can connect with Andy Clement, the AspectJ maintainer. He is so swamped with his day-time job though, he hardly ever has any free cycles. I am trying to unburden him as much as I can, but OSGi is one of my blind spots and I hardly know the AspectJ source code. I am rather an advanced user.
QUESTION
I am using the following sample code to understand AspectJ:
...ANSWER
Answered 2021-Mar-03 at 04:10You are mixing a whole lot of stuff there:
- Freefair post-compile-time weaving plugin: This is unnecessary because you have Java source code and can compile it together with the aspect using normal compile-time weaving.
- AspectJ Maven plugin: This is useless because you cannot simply use a Maven plugin in Gradle.
- AspectJ load-time weaving Java agent: This is unnecessary because, like I said, you can use normal compile-time weaving here. You also do not need aop.xml if you do not use
-javaagent:
.
I guess you could use all three options, compile-time, post-compile-time and load-time weaving, but you should decide which one and not mix them. You also should decide if you want to use Gradle or Maven and also not try to mix them.
This is how compile-time weaving works:
- Put both the application and aspect code in directory
src/main/aspectj
. - Simplify your Gradle build file to:
QUESTION
ANSWER
Answered 2020-Dec-04 at 01:42Normally I do my AspectJ stuff by setting up Maven projects which just work in Eclipse and IntelliJ IDEA. In order to help you I just tried setting up a simple Java + AspectJ project from scratch in IDEA. This is what I did (I also had to play around a bit):
- Switch to Ajc as project compiler, set path to aspectjtools library and activate toggle for delegating to Javac for post-compile weaving and non-AspectJ projects
- Add aspectjrt library to project, either as a path to a JAR or using Maven coordinates
- Add aspectjrt library as dependency in all AspectJ-related modules and add AspectJ facet
- Edit AspectJ facet, activate post-compile weaving
If you have your aspects in a separate module, please also make sure to add that module as a dependency to the Java module and also add it to the aspect path.
Please also note that if optionally you wish to use Javac for compiling the aspect module, all aspects have to be in @AspectJ syntax, not in native syntax, otherwise you cannot delegate to Javac but have to use Ajc for the aspect module too. Either way, both modules need to have an AspectJ facet.

I have a Spring Boot + Kotlin + Gradle project. I'd like to create a small library for my use-cases. This library should use AOP to remove some cross cutting concerns I observed.

ANSWER
Answered 2020-Oct-10 at 02:22This looks like the 347th duplicate of a classical Spring AOP question: If you read the manual, you will notice that Spring AOP only works for Spring components, e.g. declared via @Component
or @Bean
.
Your TestCandidate
seems to be a POJO, so Spring does not know about it. Also if you make it a component, make sure you get an instance from the container and do not just create one via constructor call in your test.

Install ajc
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
