Change maven dependency's version by using different maven profiles - maven

I have two projects, project A is depending on project B, so normally, I'd have the following section in my projectA/pom.xml:
<dependency>
<artifactId>projectB</artifactId>
<groupId>blabla</groupId>
<version>version1</version>
</dependency>
What I am trying to achieve is very straight forward, does maven profile allow me to do anything like:
if(profileA) {
<version>version1</version>
}
else {
<version>version2</version>
}

Yes, this can be done (put activeByDefault to whichever profile you need to be default).
<dependency>
<artifactId>projectB</artifactId>
<groupId>blabla</groupId>
<version>${dependency.version}</version>
</dependency>
...
<profiles>
<profile>
<id>first</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<dependency.version>1.2.3</dependency.version>
</properties>
</profile>
<profile>
<id>second</id>
<properties>
<dependency.version>2.3.4</dependency.version>
</properties>
</profile>
</profiles>

Maven profiles change groupId

We have three profiles and each one needs to set name and groupId for our clients, but my solution shows warnings in Jenkins compilation and haven't transitive dependencys. A part of my pom:
<artifactId>persistenceLib-${proyecto.nombre}</artifactId>
<version>1.0.0</version>
<groupId>${proyecto.groupId}</groupId>
<dependencies>...</dependencies>
<profiles>
<profile>
<id>client1</id>
<activation><activeByDefault>true</activeByDefault></activation>
<properties>
<proyecto.nombre>Client1Lib</proyecto.nombre>
<proyecto.groupId>com.Client1.product</proyecto.groupId>
</properties>
</profile>
<profile>
<id>client2</id>
<activation><activeByDefault>false</activeByDefault></activation>
<properties>
<proyecto.nombre>Client2Lib</proyecto.nombre>
<proyecto.groupId>com.Client2.product</proyecto.groupId>
</properties>
</profile>
<profile>
<id>client3</id>
<activation><activeByDefault>false</activeByDefault></activation>
<properties>
<proyecto.nombre>Client3Lib</proyecto.nombre>
<proyecto.groupId>com.Client3.product</proyecto.groupId>
</properties>
</profile>
</profiles>
¿What is the correct way for a dynamic IDs?

can't deactivate activeBydefault profile on maven build

I use maven 3.8.5 in a web application with different layer. The parent pom is something similar to the follow:
<profiles>
<profile>
<id>dev</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<dependencies>
<dependency>
<groupId>org.flywaydb</groupId>
<artifactId>flyway-core</artifactId>
<version>6.4.0</version>
</dependency>
</dependencies>
</profile>
<profile>
<id>other</id>
<activation>
<activeByDefault>false</activeByDefault>
</activation>
</profile>
</profiles>
Now if I manually change the activationByDefault of dev profile from true to false and activationByDefault of other profile from false to true when I build (mvn clean package) everything goes fine.
Instead If I perform a build command like follow to obtain the same result:
mvn clean package -P other
doesn't work.. and I still find flyway library in my project. What's wrong?

How to acess a property under specific profile in Maven

I have 2 pom files - ParentPOM and ChildPOM. I want to Access property1 in ParentPOM in ChildPOM. I know this can be done by making ParentPOM as the parent for ChildPOM and use ${property1}. But property1 is defined in 2 profiles - trunk and release and I always want to get the value of property1 defined in release. How do I do that? ie:- In the below example, I want the value should be 0.0.2 and not 0.0.1 when I Access property1 in ChildPOM.
Note:I cannot modify ParentPOM
<project>
<modelVersion>x.x.x</modelVersion>
<artifactId>ParentPOM</artifactId>
<version>1.0.0</version>
<packaging>pom</packaging>
<name>ParentPOM</name>
<profiles>
<profile>
<id>trunk</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<property1>0.0.1</property1>
</properties>
</profile>
<profile>
<id>release</id>
<properties>
<property1>0.0.2</property1>
</properties>
</profile>
</profiles>
</project>
<project>
<modelVersion>x.x.x</modelVersion>
<parent>
<groupId>com.temp</groupId>
<artifactId>ParentPOM</artifactId>
<version>1.0.0</version>
</parent>
<artifactId>ChildPOM</artifactId>
<version>2.0.0</version>
<packaging>pom</packaging>
<name>ChildPOM</name>
<profiles>
<profile>
<id>trunk</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<property1>x.x.x</property1>
</properties>
</profile>
<profile>
<id>release</id>
<properties>
<property1>y.y.y</property1>
</properties>
</profile>
</profiles>
<dependencies>
<dependency>
<groupId>com.xxx</groupId>
<artifactId>xxx</artifactId>
<version>${property1}</version>
</dependency>
</dependencies>
</project>
Introduce a property "releaseProperty1" in your parent pom. Use this property both for the definition of "property1" in the profile "release" and for your use cases in the child pom.
There is one cleanish solution, but it all depends on the why... why do you want this?
The solution is: removing the release-profile from child and execute Maven like this: mvn <goal> -Prelease,!trunk, i.e enable release profile and disable trunk profile.
To confirm this solution, run mvn help:evaluate -Dexpression=property1 -Prelease,!trunk

Using profiles in Netbeans and Maven multimodule project to build for Windows and Linux

In a NetBeans "workspace" for Java there are several projects (all dirs are on same level):
Main
MainExecutable (contains the main(String[] args) method for debugging)
JNILibrary (only available for Linux)
10 further projects
And I am trying to make it debuggable on Windows by providing "stubs" (just some empty methods) source code for Windows through the profile in JNILibrary\pom.xml:
<groupId>com.example</groupId>
<artifactId>jnilibrary</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<parent>
<groupId>com.example.test</groupId>
<artifactId>Main</artifactId>
<version>0.0.1-SNAPSHOT</version>
<relativePath>../Main/pom.xml</relativePath>
</parent>
<build>
<sourceDirectory>${src.dir}</sourceDirectory>
</build>
<profiles>
<profile>
<id>windows</id>
<activation>
<activeByDefault>false</activeByDefault>
</activation>
<properties>
<src.dir>src/windows/java</src.dir>
</properties>
</profile>
<profile>
<id>linux</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<src.dir>src/linux/java</src.dir>
</properties>
</profile>
</profiles>
After that I am able to select Set Configuration -> linux or Set Configuration -> Windows, when I right-click on the JNILibrary project in NetBeans.
Unfortunately, when I try to debug the MainExecutable project - it still (builds and) starts the Linux version - and fails to start on my Windows PC.
Could someone please point into right direction on how to solve my problem?
Here is an excerpt from Main\pom.xml:
<groupId>com.example.test</groupId>
<artifactId>Main</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>pom</packaging>
<name>Main</name>
<modules>
<module>../MainExecutable</module>
<module>../jnilibrary</module>
<module>../10/further/modules</module>
</modules>
And here an excerpt from MainExecutable\pom.xml:
<parent>
<groupId>com.example.test</groupId>
<artifactId>Main</artifactId>
<relativePath>../Main</relativePath>
<version>0.0.1-SNAPSHOT</version>
</parent>
<artifactId>MainExecutable</artifactId>
<packaging>jar</packaging>
As you wrote, move the 2 profiles to Main/pom.xml and add to both of them new property jnilibrary.src.dir
<profiles>
<profile>
<id>windows</id>
<activation>
<activeByDefault>false</activeByDefault>
</activation>
<properties>
<jnilibrary.src.dir>src/windows/java</src.dir>
</properties>
</profile>
<profile>
<id>linux</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<jnilibrary.src.dir>src/linux/java</src.dir>
</properties>
</profile>
</profiles>
and use that property in JNILibrary\pom.xml
<build>
<sourceDirectory>${jnilibrary.src.dir}</sourceDirectory>
</build>
You can use the OS Name to activate the profile:
<build>
<sourceDirectory>${src.dir}</sourceDirectory>
</build>
<profiles>
<profile>
<id>windows</id>
<activation>
<os>
<name>Windows</name>
</os>
</activation>
<properties>
<src.dir>src/windows/java</src.dir>
</properties>
</profile>
<profile>
<id>linux</id>
<activation>
<os>
<name>Linux</name>
</os>
</activation>
<properties>
<src.dir>src/linux/java</src.dir>
</properties>
</profile>
</profiles>

How to generate two sonar reports from the same project?

I would like to create two sets of Sonar reports from the same project. One would have everything covered and the other one would have some packages excluded.
Is this possible and if so, how to do such?
Edit: Setting exclusions is not a problem but having two reports is.
Create new profile in maven and add call sonar with new branch for each profile: mvn clean install -Pprofile1 sonar:sonar -Dsonar.branch=BRANCH1
<properties>
<sonar.branch>
DEFAULT_BRANCH
</sonar.branch>
</properties>
<profiles>
<profile>
<id>sonar</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<sonar.host.url>
http://localhost:9000
</sonar.host.url>
</properties>
</profile>
<profile>
<id>profile1</id>
<properties>
<!-- Optional URL to server. Default value is http://localhost:9000 -->
<sonar.host.url>
http://myserver:9000
</sonar.host.url>
</properties>
</profile>
</profiles>
