Reporting and Merging multi-module jacoco reports with report-aggregate

Attempting to get one jacoco report that will show all the results from multiple modules.
I am able to see that each of the sub-modules have a jacoco.exec after building the project but unsure of how to get it to output one report that will have all the results from every module combined.
This is what I have included in my Root pom.xml:
<plugin>
<groupId>#project.groupId#</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>#project.version#</version>
</plugin>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<executions>
<execution>
<id>prepare-agent</id>
<goals>
<goal>prepare-agent</goal>
</goals>
</execution>
</executions>
</plugin>
I created a new module explicitly for reporting purposes. (e.g. report-aggregate-module)
Deleted the group ids and used generic artifact ids for this example:
This is what I put in the pom.xml for this report-aggregate sub-module:

Everything seems to compile okay, the jacoco exec doesn't seem to get created for the report-aggregate-module. Anyone know a solution to this or if I'm doing this incorrectly?

Sorry if this comes a late answer.
I assume that your root pom.xml is an aggregater, with <modules> consisting of module1, module2, and report-aggregate. This is the cause of your trouble: as your root pom.xml is an aggregator, it runs JaCoCo BEFORE your submodules do, so your final report is empty. You should:
Move the configuration of goal report-aggregate of the jacoco-maven-plugin from the root POM to the report-aggregate POM. This should do the trick, because your report-aggregate POM uses <dependencies>, not <modules>.
Keep the configuration of goal prepare-agent of the jacoco-maven-plugin in the root POM.
I suggest you look at the JaCoCo forum https://groups.google.com/forum/#!topic/jacoco/FpdLbxsXSTY. It refers to a complete demo integration test https://github.com/jacoco/jacoco/tree/master/jacoco-maven-plugin.test/it/it-report-aggregate.

Include source package and dependency only for a profile with Spring Boot maven plugin

In a Spring Boot based project of mine I want to create two different builds from the same project.
The decision on which build is generated should come from a maven profile.
I want to create one build (full) which includes a certain folder src/main/java/com/example/demo/full and a certain dependency, and a second build (default or light) build which does not include them.
Including the dependencies for build full works, but I don't know how to make sure the folder src/main/java/com/example/demo/full is only compiled for the full build.
Here my pom.xml:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

How can I manage to have the mentioned source-folder only compiled for profile full?

Add a second src folder like scr\foo and then add a profile in maven configure this src folder.
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<source>src/foo/</source>
</sources>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</profile>
</profiles>
Here the source folder is added using the Build Helper Plugin plugin for maven. As it is embedded in the build section of the specific profile, it is only active while executing maven with this profile (see the activation section)

there are problem with disabling one of your maven-source-plugin if this dependency is a part of parent which you cant not give ID to, ill recomend to use phase none with this code to one of your pom.xml files that will disable this.
I also recommend to use command: mvn -Prelease-profile help:effective-pom
to print if you have two of dependencies maven-source-plugin in your code, if yes, disable one of them with this code below:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-source-plugin</artifactId>
<executions>
<execution>
<id>attach-sources</id>
<phase>none</phase>

Maven + Eclipse cannot build path

I have found this solution on stackoverflow. Warning - Build path specifies execution environment J2SE-1.4
I am getting almost the same problem but instead of 1-4 i am having 1-6. Unfortunately I don't really understand this configuration thing. It's new thing to me. I am trying second answer to get this working. I found this pom.xml in src under my project and it's xml looks like this:

What and where should I add sth? I am using Eclipse on Windows 7. My version of java is: 1.8.0.25-b18 Words like plugin and Maven and JUnit are highlighted red. I would be grateful for help!

Try
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<source>1.4</source>
<target>1.4</target>
</configuration>
</plugin>
And then regenerate the Eclipse project with mvn eclipse:eclipse.

Not generating OSGI-INF folder

I am new to OSGI.I have been having trouble to get OSGI-INF folder in generated jar file.
I need to have folder structure like as below
META-INF
OSGI-INF
Com.mine.cq

Why OSGI-INF folder is not in the .jar file? I need to set some information in OSGO-INF folder since I have to register my component as a OSGI service.
Please guide me to get it done.

Although being pretty late, I'll post my 2 cents about this issue for future reference.
As already pointed out, you can have the "packaging" of the bundle set to "jar" if you follow the instructions given in Maven bundle plugin documentation.
There is just a little gotcha: with that configuration, you need to explicitly add <exportScr>true</exportScr> inside the plugin configuration in order to properly create the SCR xml file (also remember to adjust manifest location, since in the documentation that piece is absent!).
You can see an example here (that's totally different from yours, but I assume you can easily reduce it on your code, if you're still interested):

Your pom.xml needs to have a packaging type of "bundle" rather than "jar". If you want the packaging type to be "jar", use this:
http://felix.apache.org/site/apache-felix-maven-bundle-plugin-bnd.html#ApacheFelixMavenBundlePlugin%28BND%29-AddingOSGimetadatatoexistingprojectswithoutchangingthepackagingtype
EDIT: Oh! That's only problem one. The other problem is that I don't think you can generate
OSGI-INF with the maven-bundle-plugin. You need to create the OSGI-INF folder yourself within src/main/resources or use a plugin that generates OSGI-INF.
The maven-scr-plugin can generate OSGI-INF, but it's only useful if you are using SCR. Maven SCR Plugin - Not generating OSGI-INF folder

Retrotranslator Maven Plugin does not recognize backport packages on another project

I'm trying to use Retrotranslator Maven Plugin to facilitate development on a pre-JDK1.4 environment. I have a maven module called xyz-core where there is the package br.com.company.xyz.core.backport that I want to use as a universal backport package.
The problem is: the plugin does not find the package. If I copy that package to this project, it works. But I need the backport package on a separate artifact because it will be used in many other projects.
