aggregating surefire reports in MultiModule project

I have multimodule maven project I want to get aggregated surefire reports . I tried below approach but I dont see aggregated surefire report generated. I could see report generated for individual modules.
I have added below plugin configuration in indvidual Modules (packaging jar)
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<dependencies>
<dependency>
<groupId>org.apache.maven.surefire</groupId>
<artifactId>surefire-junit4</artifactId>
<version>2.22.0</version>
</dependency>
</dependencies>
<configuration>
<useManifestOnlyJar>false</useManifestOnlyJar>
<includes>
<include>**/*.java</include>
</includes>
</configuration>
</plugin>
<reporting>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-report-plugin</artifactId>
<inherited>false</inherited>
<configuration>
<aggregate>true</aggregate>
<linkXRef>true</linkXRef>
</configuration>
</plugin>
</plugins>
</reporting>
And below in root level pom (packaging type pom)
<reporting>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-report-plugin</artifactId>
<version>${version.plugin.surefire}</version>
<inherited>false</inherited>
<configuration>
<aggregate>true</aggregate>
<linkXRef>true</linkXRef>
</configuration>
</plugin>
</plugins>
</reporting>
Could some one please help where I am going wrong ?

Try with mvn surefire-report:report -Daggregate=true

Why Eclipse displayed the error " <failOnMissingWebXml> is set to true" whereas I set it to false?

I just created a simple Maven project, i want it without web.xml.
Eclipse display this error while I set it to true (see pom.xml) :
<build>
<finalName>ROOT</finalName>
<!-- <sourceDirectory>src</sourceDirectory> -->
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>3.2.1</version>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
</plugins>
</build>
Does anybody has an idea of what is involved here ?

maven-jar-plugin not finding my main class

I've got a Java/Selenium/TestNG/Maven project. I can successfully create the myproj-0.0.1-SNAPSHOT.jar file. When I try to run it I'm getting an error:
$ java -jar myproj-0.0.1-SNAPSHOT.jar
Error: Could not find or load main class utilities.MavenTestInvoker
My main goal is to be able to run this SNAPSHOT.jar file to run my test cases on a remote machine.
I'm using a build plugin in my pom.xml:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.6.0</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19.1</version>
<configuration>
<suiteXmlFiles>
<suiteXmlFile>testng.xml</suiteXmlFile>
</suiteXmlFiles>
<skipTests>true</skipTests>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>utilities.MavenTestInvoker</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
</plugins>
</build>
When I build the project I'm using the maven command: "mvn clean package shade:shade"
That creates my uber jar.
Here are the dependencies:
<dependencies>
<dependency>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>3.0.1</version>
</dependency>
<dependency>
<groupId>org.apache.maven.shared</groupId>
<artifactId>maven-invoker</artifactId>
<version>2.2</version>
</dependency>
<dependency>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.4.3</version>
</dependency>
plus some others
</dependencies>
What am I doing incorrectly?

The correct usage of including plugin dependencies is as follows, you can merge the plugin dependencies at a single place -
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.6.0</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19.1</version>
<configuration>
<suiteXmlFiles>
<suiteXmlFile>testng.xml</suiteXmlFile>
</suiteXmlFiles>
<skipTests>true</skipTests>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.3.2</version>
<!--Notice I have removed the configs here. Not required to generate the jar-->
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>3.0.1</version>
</plugin>
<plugin>
<groupId>org.apache.maven.shared</groupId>
<artifactId>maven-invoker</artifactId>
<version>2.2</version>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.4.3</version>
</plugin>
</plugins>
</pluginManagement>
</build>
Further you can edit the respective plugin configs within the same declaration.
Also for using maven-shade-plugin and maven-jar-plugin, you might want to look into the samples here and here respectively.

Remember that your project must have the right folder structure, for example your code must be in src/main/java

Eclipse deletes files under WEB-INF on every run

I'm trying to setup Maven with my GWT project but every time that I start debugging, it deletes web.xml and other files that are required to start.
Code fragment related to build from my pom.xml :
<build>
<outputDirectory>${webappDirectory}/WEB-INF/classes</outputDirectory>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>${maven-compiler-plugin.version}</version>
<configuration>
<webXml>${webappDirectory}/WEB-INF/web.xml</webXml>
<source>${target.jdk}</source>
<target>${target.jdk}</target>
<encoding>${project.build.sourceEncoding}</encoding>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>${maven-war-plugin.version}</version>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
<archiveClasses>true</archiveClasses>
</configuration>
</plugin>
</plugins>
</build>

No classes in war maven

I'm pretty new in using og maven, an I got stuck. mvn clean install does not generate classes :(
I'm using the following code in my pom :
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>2.4</version>
<configuration>
<webXml>WebContent\WEB-INF\web.xml</webXml>
<archiveClasses>true</archiveClasses>
</configuration>
</plugin>

Please read the usage page first, it will show the expected folder structure.
So java sources are expected in src/main/java.
BTW: If you still want to use WebContent, set the warSourceDirectory to WebContent, remove all other configuration.
