Maven not cleaning child project target folder - java

I set up a sample project to understand the clean plugin in maven as to how it cleans a child project when the mvn clean:clean is run from the parent project location. Somehow, I see that maven deletes target of parent project but not of child project. This confuses me.
Here is my project structure :
Now the java code is minimal in the project - just a hello world project. I will just show the POM files.
POM for parent project :
<?xml version="1.0" encoding="UTF-8"?>

</project>
POM for child project :
<?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"

<artifactId>learning-maven</artifactId>
<version>1.0-SNAPSHOT</version>
</parent>
<artifactId>child-module1</artifactId>
<version>1.0-SNAPSHOT</version>
</project>
I am only focussing on the clean plugin and not on anything else.
The POM are hence minimal. My question is what is wrong with child pom that maven not cleaning it's target folder ?
I show the <build> tag in effective pom of child project too :

You have to indicate in the parent POM the child modules, i.e :
<modules>
<module>../child-module1</module>
</modules>

As Arnaud said, you need to put in you pom parent the child modules. You don't need paths, just the artifactId
<modules>
<module>child-module1</module>
</modules>

Maven: Generate both jar and war for the project using same pom.xml

I have a project and i need to generate both jar and war of the project using same pom.xml.
So when i run 'mvn clean install' it should generate both jar and war in my ~/m2 directory.
I needed this jar to build my second project.
Below is the sample pom.xml.
<artifactId>demo-service</artifactId>
<name>demo-service</name>
<description>service demo</description>

Thanks.
You can try options archiveClasses and attachClasses of maven-war-plugin
So your configuration can look like:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.3.2</version>
<configuration>
<archiveClasses>true</archiveClasses>
<attachClasses>true</attachClasses>
</configuration>
</plugin>
You should also use maven-install-plugin
Try this:

Mystery directory created during maven compile

I have disabled all of the plugins in my module's pom.xml file and in the parent pom.xml file. I type
`mvn clean install -U`
and in the same directory
`${project.basedir}/src/main/site/resources/repo`
appears, approximately during the time the compile phase executes.
Any ideas about what could be causing this?

Aspectj maven plugin & jetty-all compile warning

I use aspectj-maven-plugin and jetty-all in my java project.
But after run "mvn clean install" there will be a warning message.
....

My mixed Scala/Java Maven project doesn't compile

I have a mixed Scala/Java project that doesn't compile well.
The problem arises when Java code is trying to call Scala code in the same package.
Of course, I have the standard layout:
src/main/java
src/main/scala
src/test/java
src/test/scala
I've looked at other similar Stackoverflow questions but this question is a little outdated. This other question doesn't help either.
I have also followed the scala-maven-plugin documentation page.

I have tried unsuccessfully to follow this blog post.
IDEA project with Scala plugin imported from the pom.xml can compile and run my project successfully.
What is the right way of doing it?
Does the Java code gets compiled twice? First by the Scala plugin and the by the Java plugin?.
Here is a working example of pom.xml :

Problem 1
At first I thought the problem was due to using a modern version of the maven-compiler-plugin. I was using version 3.0 instead of 2.0.2.
The solution has been:
- Remove the maven-compiler-plugin
- Add this setting: incremental
Finally my pom.xml is this:
<plugin>
<groupId>net.alchim31.maven</groupId>
<artifactId>scala-maven-plugin</artifactId>

Problem 2
Another problem I was experiencing is this:
<dependencies>
<dependency>
<groupId>org.json4s</groupId>
<artifactId>json4s-native_${scala.version}</artifactId>
<version>3.2.9</version>
</dependency>
<dependency>
<groupId>org.scala-lang</groupId>
<artifactId>scala-library</artifactId>
<version>${scala.version}.4</version>
</dependency>
</dependencies>
<properties>
<scala.version>2.10</scala.version>
</properties>
This make this solved problem arise:
https://issues.scala-lang.org/browse/SI-5733
Probably it was using an old version of the Scala compiler.
The solution has been to rename scala.version to scala.major, as this property has a special meaning.
In order to get the scala-maven-plugin to respect Java 1.8, but still allow mixed compilation of java and scala, we use this:
...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.5</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
<executions>
<execution>
<id>default-compile</id>
<phase>none</phase>
</execution>
</executions>
</plugin>
<plugin>
<groupId>net.alchim31.maven</groupId>
<artifactId>scala-maven-plugin</artifactId>
<version>3.2.2</version>
<configuration>
<recompileMode>incremental</recompileMode>
</configuration>
<executions>
<execution>
<goals>
<goal>compile</goal>
<goal>testCompile</goal>
</goals>
</execution>
</executions>
</plugin>
...
I add blow code at pom.xml file <build> block and working good!
