            The new JRebel Agent no longer works using -javaagent. This change affects users previously running with the Legacy Agent from a command line (as well as on a remote machine or container) from here:

            Remove -javaagent argument from javaoptions or downgrade to an older JRebel version. Its working well just with -agentpath argument. Tested on newer Hybris + latest Java 11 + latest JRebel



            How to run multiple hazelcast cluster in one deployment?
            Asked 2022-Jan-13 at 08:35

            I'm deploying hazelcast on k8s using the helmchart on github currently on revision 5.3.2.

            How would one go about running two clusters, say dev_cache and qa_cache in one helm deployment each with different members? Is that possible?

            I see the fields



            Answered 2022-Jan-13 at 08:35

            In one Helm deployment, you always run one Hazelcast cluster. You need to run Helm command twice to create 2 separate Hazelcast clusters.



            Why is "compile" called 2 times when calling "run" in SBT Play Framework Project
            Asked 2021-Dec-23 at 08:57

            In my play framework project using SBT, I'm trying to run a custom task before the compile task. This is easily done by adding this in the build.sbt.



            Answered 2021-Dec-23 at 08:57

            I can't tell you why you're seeing the behaviour you're observing. I can reproduce the error with SBT 1.3.13. When I use SBT 1.4.9 the custom task only runs once as you would expect.



            VueJS and Jest. Testing component with local imported mixin
            Asked 2021-Oct-26 at 06:21

            I am learning VueJS by recreating MineOS interface. I have replicated a bunch of functionality without actually calling the backend. I've run into an issue with unit testing. It looks like I've done everything I can but I think that my mixin method isn't being called. I think what I am doing is:

            1. mocking the store/state with my test (which I have done in my login spec).
            2. mocking the action that the mixin uses and assigning to the store, which should be mapped in the mixin.
            3. populating the java_xmx input with 235 and then triggering the input event.
            4. trigger next tick
            5. interrogate the action to see if it's been called.

            Is the only way to test with mixins to import globally and mock?




            Answered 2021-Oct-26 at 06:21

            Figured it out finally!

            There were a couple of issues that required fixing for the entire test to pass. The issue at hand was that the mixin didn't appear to be utilised in the test. I required to change @input="updateConfig('java', 'java_xmx', $event)" to @input.native="updateConfig('java', 'java_xmx', $event)" of course! .native.

            I then discovered that I hadn't mocked my state and had to do that.

            The final code for the test is



            Packaging via jpackage Could not find or load main class
            Asked 2021-Oct-10 at 00:20

            Using jpackage I can't get a pkg to run on macOS. The installation goes as expected however when I launch the installed application it starts then immediately stops.

            Since I'm trying to run a Springboot app, the trick is to not try and launch your main class as you'd typically do but instead to use org.springframework.boot.loader.JarLauncher

            This is more properly explained in a blog post by the Spring team

            So a complete working example with Springboot looks like:



            Reading configuration files from unit tests
            Asked 2021-May-11 at 10:41

            I have a very simply project.




            Answered 2021-May-11 at 10:41

            The best practice is to place application.conf into src/main/resources/ for regular use and into src/test/resources/ for testing. You'll have 2 conf files with different values in test. If you don't need to change config for test you can simply keep one conf file in main.

            You don't have to override the file explicitly with -Dconfig.resource or -Dconfig.file for your tests because loading resources from class path will work as you expect out of the box and your test config will be used. -D option is mostly used at runtime to provide external configuration or in some complex build scenarios.

            If you use -Dconfig.resource or -Dconfig.file pay attention to the path. config.resource is just a filename, i.e. application.conf which will be loaded as resource while config.file is an absolute or relative file path.

            If you are making a library you can get fancy with reference.conf file having default values and application.conf overriding them. This could also work in your scenario but would be more confusing because that's not the purpose or reference file.

            For the purposes of testing just use 2 application.conf files.

            Additionally, here are some options to override config at runtime:

            Overriding multiple config values in Typesafe config when using an uberjar to deploy.

            Overriding configuration with environment variables in typesafe config

            Scala environment ${USER} in application.conf

            Error when working with AspectJ and Scala
            Asked 2021-May-07 at 13:09

            I am trying to work with Scala and AspectJ on IntelliJ as the IDE. #The file structure

            Sample.scala - (The class which consists of the main method)



            Answered 2021-May-07 at 13:09

            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:



            Unable to build Docker images through Jenkins installed on Kubernetes
            Asked 2021-May-03 at 05:16

            I used the following helm chart to install Jenkins


            The problem is it does't build docker images, saying there's no docker. Docker was installed on host with sudo apt install docker-ce docker-ce-cli



            Answered 2021-Apr-08 at 20:25

            You are running Jenkins itself as a container. Therefore the docker command line application must be present in the container, not the host.

            Easiest solution: Use a Jenkins docker image that contains the docker cli already, for example



            How to modify the apktool path
            Asked 2021-Apr-14 at 05:42

            4.1 dirthy, but this version was not official of apktool, and I was having some problems, so I upgraded to version 2.5.0 and official, however I want my apktool folder to be in /usr/share but if I move my apktool folder to /usr/share when I run apktool the result is this:



            Answered 2021-Apr-14 at 05:42

            If you follow the steps to install apktool:

            You will notice there are 2 files you need:

            1. a script (the one you posted), which you should name apktool and set to executable on linux chmod +x apktool
            2. a jar file: apktool.jar

            You need to have both files in the same directory for the script to work, so if you've moved the apktool file to /usr/share/apktool, you need to also move apktool.jar to /usr/share/apktool.jar
