CheckStyle from maven: how to fail at the very end? - maven

I have a multi-module maven build configured to run CheckStyle. It works, but it fails as soon as it comes across a module with a violation. How can I process all modules but not fail until the very end? I'd like to be able to see all violations without having to fix/re-run repeatedly.

I'd advise to do this in your IDE, to get checkstyle violations feedback while you code, and not only late when building using Maven. Still keep maven checking for violations, and fail a build as early as possible, on first module with violations.
E.g. there is eclipse-cs, checkstyle plugin for eclipse IDE. To have both maven-checkstyle-plugin and eclipce-cs use same checkstyle configuration file, install m2e eclipse plugin and it's extensions including one for eclipse-cs.

can you build a maven project inside of a gradle wrapper

It may be just that I have a general misunderstanding how gradle build works, but it feels to me that I can not build a maven file inside of a gradle build. Since gradle uses the gradle.build file, and maven uses a pom.xml, it does not seem as though I can do this. I have multiple maven projects that I would like to wrap up with a gradle wrapper. I can not find ANYTHING on whether this is even possible.
Both Maven and Gradle are build tools and you should only use one of them for a given project.
If you have existing Maven projects and like the functionality provided by the Gradle wrapper, there is a similar wrapper for Maven (note that this is currently a third-party plugin but they plan to include it in the upcoming release 3.7 of Maven).
Alternatively you could convert your projects entirely to Gradle.

maven plugin execution issue

I am using aspectj in a project. when i add the aspectj-maven-plugin to the build, the aspects are woven in and things work as expected. however, i get an error in the POM saying that the plugin execution is not covered by lifecycle configuration.
from what i've read in other problems, it says the solution is to simply wrap the plugin in a pluginManagement tag. that does seem to get rid of the error, however, when i do a mvn clean install, the aspectj plugin no longer runs. any idea on how to solve that problem?

sonar-maven-plugin with multi-module maven

I have a multi-module maven project which seems to have correctly generated OWASP dependency reports at both the parent and child module /target dirs using the org.owasp:dependency-check-maven plugin as so:
However, referencing the plugin docs, and executing the sonar-maven-plugin as below, I just can't work out what the correct command should be, any combination seems to lead to a build failure:
mvn sonar:sonar -Dsonar.sources=? -Dsonar.dependencyCheck.reportPath=?
Can anyone explain how to configure a multi-module maven project and have Sonar recognise the OWASP dependency reports?
Below is a screenshot of the starting point - we've had a CI pipeline up and running producing separate unit and integration test coverage stats for each of the submodules for some time.
Ok, so have contacted the author and the dependency-check-sonar-plugin doesn't work with a multi-module maven project.
So we are just going to produce a static artefact in a one-off fashion and not attempt to integrate with our CI pipeline.

What is the purpose of the # symbol in <groupId>#project.groupId#</groupId>?

I'm trying to run 'mvn clean install' in a sub-module of a multi-module project. The project is Jacoco but I assume it's more an issue of me not understanding how Maven is being used here than an issue with Jacoco itself.
https://github.com/jacoco/jacoco/blob/master/jacoco-maven-plugin.test/it/it-site/pom.xml
I get the following error:
[ERROR] Plugin #project.groupId#:jacoco-maven-plugin:#project.version#
or one of its dependencies could not be resolved: Failed to read
artifact descriptor for
#project.groupId#:jacoco-maven-plugin:jar:#project.version#
I see the following in the pom:
<groupId>#project.groupId#</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
I'm not familiar with using the # symbol in #project.groupId# although i assume it is somehow supposed to get substituted at runtime.
I can run Maven from the top level pom and I even see [INFO] Building: it-site/pom.xml in the log but a target directory is not created there.
A nudge in the right direction would be appreciated.
This probably has something to do with the pom file here: https://github.com/jacoco/jacoco/blob/master/jacoco-maven-plugin.test/pom.xml
It is using a plugin called the maven invoker.
The Invoker Plugin is used to run a set of Maven projects. The plugin can determine whether each project execution is successful, and optionally can verify the output generated from a given project execution.
And if you read about filtering files with this plugin, it mentions:
POM files selected by the include/exclude patterns. The tokens to be filtered must be enclosed in #...# to avoid interferences with Maven's normal POM interpolation, i.e. use #project.version# instead of ${project.version}.
Regarding why the Invoker Plugin and filtering is being used here...
The Spring Boot documentation provides some relevant background on why that is. Although the docs are for Spring Boot, i think it applies to testing all plugins (which Jacoco is).
Multi-module Maven builds cannot directly include maven plugins that
are part of the reactor unless they have previously been built. ...
The standard build works around this restriction by launching the
samples via the maven-invoker-plugin so that they are not part of the
reactor.
The sample application are used as integration tests during the build
(when you mvn install). Due to the fact that they make use of the
spring-boot-maven-plugin they cannot be called directly, and so
instead are launched via the maven-invoker-plugin.

How to configure/use CheckStyle in Hudson/Jenkins?

I want to learn how to use CheckStyle.
I am doing static code analysis in Hudson, as first part, I installed Static Analyser and CheckStyle plugins in Hudson. But I am not able to find out how to use it in official Hudson checkstyple page also.
official page : http://wiki.hudson-ci.org/display/HUDSON/Checkstyle+Plugin
I saw some documents in Maven checkstyle plugin that we have to mention some configuration in pom file and run the targets.
Then, I got doubt, if I am doing with Maven, why we need the CheckStyle plugin install in hudson?
Is it possible to configure CheckStyle in Hudson job for a Java project instead of changing in pom or not? It here is both ways, then which one is better?
Do you have the steps to configure CheckStyle plugin in Hudson?
If you've installed the plugin in Jenkins/Hudson, you should now be able to add the checkstyle goal to your project/job.
In the goals section of your Jenkins Maven job, add "checkstyle:checkstyle" to enable the checkstyle plugin to analyse your project.
