Weave | reference implementation for a weave data structure | Compression library

Configure plugin version and common settings in the parent's pluginManagement section, then simply add the plugin group ID and name to each module's plugins section where it is needed, optionally amending or changing the configuration. Adding a plugin to the parent POM even though not all modules use it, is simply wrong from a Maven perspective.

The expression is missing the else of the last if sentence. It is mandatory to have an else.

As a simplified example:

In the documentation it is mentioned that

Each FROM instruction can use a different base, and each of them begins a new stage of the build

To check what steps are cached, run the following command

OK, 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Actually, the explanation is quite simple: The plugin is outdated and ought to be updated ASAP.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:

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:

Hm, why didn't you just try? Wouldn't that have been faster than asking? OK, here are my thoughts:

• AspectJ is completely independent from Spring AOP or Spring in general. You can use it without Spring or from within a Spring application, usually via load-time weaving (LTW). The Spring manual explains how to configure that.
• If you use LTW, Spring is aware of it, either because you configure it explicitly via Spring options or simply because Spring detects the active weaving agent somehow. Either way, as soon as LTW is active, Spring deactivates its own Spring AOP.
• Concerning compile-time weaving (CTW), Spring does not know about it, because it happens during build time, before Spring is even started. Depending on what kind of AspectJ features you use, the AspectJ-enhanced classes might look no different from regular Java classes, e.g. for simple ITD field or method definitions. In most cases however, the modifications are such that you need the AspectJ runtime library aspectjrt.jar on the classpath. If that is the case, the application should run normally, with or without Spring.
• In case of Spring, I do not expect it to notice anything about you having used CTW before in the first place. Consequently, it will not deactivate Spring AOP. You should be able to use both in combination with each other. Just make sure not to declare your native aspect as a Spring component, otherwise Spring AOP would try to re-apply it. The results would be unpredictable. But the normal Spring AOP aspect components should just work normally. Of course, you also need to make sure that AspectJ Maven does not accidentally compile and weave your Spring AOP aspects as native aspects. You can achieve that by placing your AspectJ aspects into another module, creating an aspect library, and then referring to it in AspectJ Maven via configuration.

Bottom line: You cannot mix Spring AOP and AspectJ LTW, but you should be able to use Spring AOP + AspectJ CTW. You just should have good reasons to do so and understand what you are doing.

I am not a Spring user, but when answering AspectJ LTW questions here I often noticed a certain discrepancy between the Spring documentation mentioning the need for the Spring Instrument Java agent only and the real situation in which there are ways to configure Spring like that, but it is tricky. The simplest approach by far is to also add the AspectJ Weaver agent to the command line, i.e. to use something like (on a single line, of course)

Your loop is generally correct, but in Julia when you want to assign a value to a column of a dataframe or matrix you are doing boardcasting, and a boardcasting operation requires an additional dot before the operator or after the function name. So the correct way to assign df.id to 0 is df.id .= 0.

From the question, it looks like you are trying to construct query from CustomerId which can be wrapped inside source or destination. The code you have had some null "" values which is not acceptable while concatenating.

Here is how I would construct the DW by importing string module.

Is there a way to prevent inter-namespace communication of pods in Kubernetes WITHOUT using network policy?

Network policies was create for that exact purpose and as per documents you need CNI that supports them. In other way they will be ignored.

Network policies are implemented by the network plugin. To use network policies, you must be using a networking solution which supports NetworkPolicy. Creating a NetworkPolicy resource without a controller that implements it will have no effect.

If your only option is to use flannel for networking, you can install Calico network policy to secure cluster communications. So basically you are installing calico for policy and flannel for networking commonly known as Canal. You can find more details in calico docs

Here's also a good answer how to setup calico with containerd that you might find useful for your case.
