while building a pipeline on Jenkins for building a springboot application, I noticed that the build fails with the following message: Required context class hudson.FilePath is missing. Searching on the internet I find examples of json configurations to be provided to the Jenkins service. My doubt is on the web interface: https://prnt.sc/6SIZKYRmfYGI where it allows me to create pipelines, but I don't know where to fill in the required filepath. Would anyone know how to give me directions?

I am working on creating an internal library/starter for my team that will add support for creating native images, providing all of the hints that our currently unsupported dependencies will need. I really like providing the metadata via code (using RuntimeHintsRegistrar), but there are also certain classes that need to be initialized at build time for whatever reason.
Right now I'm passing the --initialize-at-build-time and the classes to the Spring Boot Maven Plugin via the BP_NATIVE_IMAGE_BUILD_ARGUMENTS, but ideally I'd like to avoid each consuming app having to include this in their own POM's plugin configuration.
I also understand that I can go more low-level and provide the argument inside of the META-INF/native-image directory in a native-image.properties file, but I'm not sure whether that will play nice with the Spring-provided RuntimeHintsRegistrar effectively creating that underneath the covers.
What is the best way to tell native-image the classes that should be initialized at build time without each consuming app having to pass it in their own POM? Also, if I use the GraalVM tracing agent to generate hints, will those hints play nicely with the ones that RuntimeHintsRegistrar generates?
Thanks in advance!
I am unable to build a maven AEM project because of failure to resolve cndNames.
Failed to execute goal net.adamcin.oakpal:oakpal-maven-plugin:1.5.1:scan (default) on project *******: Failed to execute package scan. Failed to resolve cndNames.: Failed to find node type definition on classpath for cndName exportnodetype.jsp
Can someone please help me out here?
The plugin you're referring to is responsible for validating the content of your package against a predefined set of node types.
Node type definitions can be used to restrict the structure of nodes in the Java Content Repository and they can be managed per instance. Some node types come out-of-the-box, such as nt:unstructured, nt:file, nt:folder and some may be specific to your project or a 3rd party tool you've installed.
In general, the content packages you're installing should only contain serialised content matching known node types. This is what the plugin validates as the project is built. In order to do that, the plugin requires a file with node type definitions, telling it what your AEM instance can recognise.
The error suggests that the plugin is failing to load this file. The documentation describes the steps required to export node types and configure the plugin by adding the definitions as a classpath resource, e.g. under src/test/resources
If the documentation doesn't help, consider having a look at the sources of the plugin to understand what it does when it's throwing the exception.
I am using optaplanner to solve a scheduling problem. I want to invoke the scheduling code from AWS Lambda (i know that Lambda's max execution time is 5 minutes and thats okay for this application)
To achieve this I have build a maven project with two modules:
module-1: scheduling optimization code
module-2: aws lambda handler ( calls scheduling code from module-1)
When i run my tests in IntelliJ Idea for module-1(that has optaplanner code), it runs fine.
When I invoke the lambda function, i get following exception:
java.lang.ExceptionInInitializerError:
java.lang.ExceptionInInitializerError
java.lang.ExceptionInInitializerError
at org.kie.api.internal.utils.ServiceRegistry.getInstance(ServiceRegistry.java:27)
...
Caused by: java.lang.RuntimeException: Child services [org.kie.api.internal.assembler.KieAssemblers] have no parent
at org.kie.api.internal.utils.ServiceDiscoveryImpl.buildMap(ServiceDiscoveryImpl.java:191)
at org.kie.api.internal.utils.ServiceDiscoveryImpl.getServices(ServiceDiscoveryImpl.java:97)
...
I have included following dependency in maven file: org.optaplanner optaplanner-core 7.7.0.Final
Also checked that jar file have drools-core, kie-api, kei-internal, drools-compiler. Does anyone know what might be the issue?
Sounds like a bug in drools when running in a restricted environment such as AWS-lambda. Please create a JIRA and link it here.
I was getting the same error attempting to run a fat jar containing an example OptaPlanner project. A little debugging revealed that the problem was services was empty when ServiceDiscoveryImpl::buildMap was invoked; I was using the first META-INF/kie.conf in the build, and as a result services were missing from that file. Naturally your tests would work properly because the class path would contain all of the dependencies (that is, several distinct META-INF/kie.conf files), and not the assembly you were attempting to execute on the lambda.
Concatenating those files instead (using an appropriate merge strategy in assembly) fixes the problem and appears appropriate given how those are loaded by ServiceDiscoveryImpl. The updated JAR runs properly as an AWS lambda.
Note: I was using the default scoreDrl from the v7.12.0.Final Cloud Balancing example.
I'm building "read-only" webservice (Google Cloud Endpoints as backend for an Android App) so I created a project using maven:
mvn archetype:generate -Dappengine-version=1.9.10 -Dfilter=com.google.appengine.archetypes:
and selecting archetype hello-endpoints-archetype to have some sample code to work on.
This works well and my app is correctly calling the service as expected (and the service is correctly supplying the data in return).
Now I have to implement an "update" service to periodically (4 to 6 times a dya) update the data supplied to the app. So I added a servlet to my project to be called by cron. Trouble is: one of the library used during this update uses multi-threads which cause an AccessControlException to be thrown because apparently multi-thread is only allowed in backend modules...
But after having read dozens of pages on google app engine, I still don't know how to "break" my application into modules so that particular servlet would be run as a backend module while the already existing servlet keep working as they do. So far, all I got was that I should use an EAR application composed of several WAR modules, but I don't even know if my current application is an EAR or not...
I'm using Eclipse Luna, maven 3.2.1 (embeded with Eclipse), google app engine 1.9.10, writing in Java
Could anyone please help me by explaining the directory structure and/or configuration files I have to look at, modify and/or add?
Thanks for any help provided!
You can find an example of multi-modules project here.
However, note that even in backend modules the threading is limited to 50 threads, as stated here.
I have created a Dynamic web project which also uses drools for providing some functionality. When i put the WAR file in Tomcat7 and the server, the drools part does not work.
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
After this line which is first line relating to drools, nothing happens.
Is some configuration required to run my project containing drools 5.5.0 Final in the Tomcat7.
Please help me. I am badly stuck and I am new to drools.
You'll have to add some facts to the working memory and execute(fire) the rules. Check out these examples on GitHub
P.S. Probably not related to Tomcat in any way. Might be worth while to try getting the rules executed from command line app first.
You need to check all the dependencies that are added to your web application (WEB-INF/lib) make sure that drools has all the required deps there, because if not it will not be able to create the knowledge builder. Most of the time if it is failing is because that you forgot to add the deps in the web app.
The following project in GitHub is a web application, containing some REST-style endpoints for validating IBANs. It uses Drools 5.5 to perform that evaluation.
https://github.com/gratiartis/sctrcd-payment-validation-web/
It generates a .war which can be loaded into Tomcat, and could be a useful starting point. The knowledge base is wrapped within a Spring service:
https://github.com/gratiartis/sctrcd-payment-validation-web/blob/master/src/main/java/com/sctrcd/payments/validation/RuleBasedIbanValidator.java
Following through how that creates a knowledge base and session might help you see where your code is going wrong.
As a bonus, you can run it up in Tomcat using "mvn tomcat7:run" to test it out immediately.
