How can I exclude folders from the WAR?

I tried to follow Maven packagingExcludes jars regex and this is how my pom.xml file looks. The full path to the node_modules is project-directory/src/main/webapp/node_modules

I added the following to exclude the nodes_modules folder but I still see that my build includes it and generating it, takes several minutes (Total time: 03:16 min)
<packagingExcludes>
%regex[node_modules]
</packagingExcludes>
How do I exclude the node_modules from my war file?

you're using regex version of packagingExcludes which is not the use case of yours. Try to specify folder path specified here as follows
<packagingExcludes>WEB-INF/node_modules/**</packagingExcludes> <!--or correct path to your folder-->

Maven parallel build failed because package used in tests not exist

My project could be built successfully with the command: mvn clean install. But I am trying to use mvn clean install -T 1C, it gives a batch of errors like package org.junit not exist or cannot find symbol XXX because of the classes import from other modules (e.g. common). I checked the entire error message, all of them are happens for classes in the test folder.
The project has multiple modules. e.g.
- common
- module1
- modele2

Maven-src-plugin & Java 11 - unable to scan class files:

I'm trying to upgrade my project setup to run on Java 11 & Sling 11. For this purpose I have been trying to upgrade my Maven compiler to 3.8.0 but this seems to be causing issues with the maven-scr-plugin; making it unable to scan a simple class containing only an enum.
The error I get when trying to build the Maven project is the following:
[ERROR] Failed to execute goal org.apache.felix:maven-scr-plugin:1.26.0:scr (generate-scr-scrdescriptor) on project foo-forms.core: {file location} : Unable to scan class files: {package.foo.class} (Class file format probably not supported by ASM ?): IllegalArgumentException -> [Help 1]

I've been troubleshooting for a little bit and my understanding is that the scr-plugin simply doesn't support the newest maven-compiler as one was released several months prior to the other (see links below):
maven-scr-plugin
maven-compiler-plugin
I was wondering if anyone had run into a similar issues and had figured out some workaround. Thank you!

By moving to Java 11 the class files you create will be compiled to Java 11 byte code. The maven-scr-plugin then has to scan this byte code to find the annotations that are applied to it. Unless you can find a version of the maven-scr-plugin that supports Java 11 byte code (I'm not aware of one) then you will need to find an alternative for creating your Declarative Services metadata.
One option would be to start using the bnd-maven-plugin or maven-bundle-plugin and the standard Declarative Services annotations instead of the Custom Felix annotations. Note that this would still involve updating those plugins to versions which can support Java 11. I believe that the bnd-maven-plugin version 4.1.0 should work properly with Java 11...

The solution is to migrate to bnd-maven-plugin which is sort of a superset of maven-bundle plugin. It has a better developer base and will be maintained for future java versions too.
AEM-acs-commons and latest maven archtype (23 at the time of this answer) too have ported to the bnd plugin.

RavenDB Java client missing StringUtils

I downloaded the RavenDB Java client 3.2.1 jar from here, created a new Java project in Ecplise, added the jar to the list of references, then took these three lines
IDocumentStore store = new DocumentStore(ravenDbUrl, "todo-db");
store.initialize();
store.executeIndex(new TodoByTitleIndex());
from here, replaced the values with my db-specific names, and expected some sign of life from the db. Instead, I'm getting "Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/lang/StringUtils".
I must admit, it's been a while since I've done Java, but surely this isn't missing something glaringly obvious, is it ?!
I have included the commons-lang3-3.5.jar file as well, but it's not taking that. Could you please point me in the right direction ?
Thanks !

Adding the "official" pom to my Eclipse project made it compile and run.
For the record, here's the pom, in case someone needs a base from which to investigate:

Cobertura code coverage test on Maven plugin

I'm trying to generate a code coverage report for a simple Maven plugin I've developed. Cobertura generates the report with the three classes in my project correctly, but it reports 0% code coverage even though the tests execute successfully. I've run it in debug mode and there are no errors or stack traces reported by Cobertura.
My configuration in the POM file is quite simple:

Cobertura works on all of my other projects (so far), is there any reason that it would failing to report coverage for a Maven plugin project?

It seems the problem was with my surefire configuration. I changed it to
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.16</version>
<executions>
<execution>
<id>test-custom-plugin</id>
<phase>test</phase>
<goals>
<goal>test</goal>
</goals>
<configuration>
<forkCount>1</forkCount>
<reuseForks>true</reuseForks>
</configuration>
</execution>
</executions>
</plugin>
and reports are now generated correctly. I got the idea for changing the fork options from a number of posts I'd seen of similar problems related to generating reports for sonar plugins, and changing the fork options resolved the issue.
