Not generate jacoco-ut.exec coverage report

Java 1.8. Maven 3.8. I want to generate coverage report of junit tests. So I use this in my pom.xml
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.4.201502262128</version>
<executions>
<execution>
<id>prepare-ut-agent</id>
<phase>process-test-classes</phase>
<goals>
<goal>prepare-agent</goal>
</goals>
<configuration>
<destFile>${project.build.directory}/jacoco-ut.exec</destFile>
<propertyName>jacoco.agent.ut.arg</propertyName>
<append>true</append>
</configuration>
</execution>
<execution>
<id>prepare-it-agent</id>
<phase>pre-integration-test</phase>
<goals>
<goal>prepare-agent</goal>
</goals>
<configuration>
<destFile>${project.build.directory}/jacoco-it.exec</destFile>
<propertyName>jacoco.agent.it.arg</propertyName>
<append>true</append>
</configuration>
</execution>
</executions>
</plugin>
Open terminal and run test like this:
mvn test -Dtest=com.my_company.myproject.ComponentServiceTest
Tests success finish. But coverage report to generate. File jacoco-it.exec is not exist in target folder

The pom.xml is missing the report goal as mentioned in the comment by #rajani-b.
Here is the configuration for the report goal.
<execution>
<id>report</id>
<goals>
<!--
Generate coverage reports in xml,csv,html formats
in folder ${project.build.directory}/site/jacoco
-->
<goal>report</goal>
</goals>
</execution>

spring-boot-maven-plugin - start JMX at random port

Small question regarding how to start jmxPort randomly, using the spring-boot-maven-plugin please.
Currently, I am running integration test with the spring-boot-maven-plugin, and it needs the jmxPort.
Hence, I am initializing it this way:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<wait>1000</wait>
<maxAttempts>180</maxAttempts>
<jmxPort>0</jmxPort>
<environmentVariables>
<SPRING_PROFILES_ACTIVE>integration</SPRING_PROFILES_ACTIVE>
</environmentVariables>
<jvmArguments>
-Dspring.application.admin.enabled=true
</jvmArguments>
</configuration>
<executions>
<execution>
<id>pre-integration-test</id>
<goals>
<goal>start</goal>
</goals>
</execution>
<execution>
<id>post-integration-test</id>
<goals>
<goal>stop</goal>
</goals>
</execution>
</executions>
</plugin>
However, the port 0 is not working.
How to start it randomly please?
Thank you

You can use for example org.codehaus.mojo.build-helper-maven-plugin
https://www.mojohaus.org/build-helper-maven-plugin/
You will add one more step to your plugin config. This step will generate variable with random port number which can be then used with the spring-boot-maven-plugin.
Your configuration will look similar to this:
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>3.2.0</version>
<executions>
<execution>
<id>reserve-network-port</id>
<goals>
<goal>reserve-network-port</goal>
</goals>
<phase>process-resources</phase>
<configuration>
<portNames>
<portName>random.jmx.port</portName>
</portNames>
<randomPort>true</randomPort>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<wait>1000</wait>
<maxAttempts>180</maxAttempts>
<jmxPort>${random.jmx.port}</jmxPort>
<environmentVariables>
<SPRING_PROFILES_ACTIVE>integration</SPRING_PROFILES_ACTIVE>
</environmentVariables>
<jvmArguments>
-Dspring.application.admin.enabled=true
</jvmArguments>
</configuration>
<executions>
<execution>
<id>pre-integration-test</id>
<goals>
<goal>start</goal>
</goals>
</execution>
<execution>
<id>post-integration-test</id>
<goals>
<goal>stop</goal>
</goals>
</execution>
</executions>

2 plugins not working simultaneously in pom

I have added 2 plugins under build tag, functionality of both the plugin's is to generate some classes under target folder. Whenever I am trying to clean install maven application, by default target gets clean each time and then installs a fresh content into target folder which is the ideal way.
But in the following code Java classes are generated only when, if there is only single plugin. I have to manually comment any one of the plugin and then I need to install maven goal and then Java classes get generated for a single plugin, same thing I need to repeat for second plugin.
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<executions>
<execution>

</executions>
<configuration>

</wsdlFiles>
<wsdlLocation>/WEB-INF/wsdl/*</wsdlLocation>
<extension>true</extension>
<target>2.2</target>
</configuration>
</plugin>
</plugins>
</build>
My question is, how can I generate Java classes simultaneously without commenting any one of the plugin under target folder?

You're specifying the same plugin twice, that's not going to work. You need to merge the two like this (move <configuration> inside <execution>):
<plugin>
<groupId>org.jvnet.jax-ws-commons</groupId>
<artifactId>jaxws-maven-plugin</artifactId>
<executions>
<execution>
<id>somefolder</id>
<phase>generate-sources</phase>
<goals>
<goal>wsimport</goal>
</goals>
<configuration>
<wsdlDirectory>src/main/webapp/WEB-INF/wsdl</wsdlDirectory>
<wsdlFiles>
<wsdlFile>myfirstwsdl.wsdl</wsdlFile>
</wsdlFiles>
<wsdlLocation>/WEB-INF/wsdl/*</wsdlLocation>
<extension>true</extension>
<target>2.2</target>
</configuration>
</execution>
<execution>
<id>wsimport</id>
<phase>generate-sources</phase>
<goals>
<goal>wsimport</goal>
</goals>
<configuration>
<wsdlDirectory>src/main/webapp/WEB-INF/wsdl</wsdlDirectory>
<wsdlFiles>
<wsdlFile>mysecondwsdl.wsdl</wsdlFile>
</wsdlFiles>
<wsdlLocation>/WEB-INF/wsdl/*</wsdlLocation>
<extension>true</extension>
<target>2.2</target>
</configuration>

maven-jaxb2-plugin VS jaxb2-maven-plugin for multiple schemas

I have multiple xsd schemas that I want to unmarshall into different packages under the same folder target/generated-sources/xjc. I tried both plugins and both seem to work fine with these 2 configurations but in case of maven-jaxb2-plugin the eclipse plugin keeps generating classes indefinitely (because of the forceRegenerate = true) but if I don't specify forceRegenerate it won't generate the second and third set of classes at all when I run mvn clean package Are there any issues with my configuration?

General advice: specify your packages in bindings.xjb rather than in different executions with individual generatePackages.
<jxb:bindings schemaLocation="common1.xsd" node="/xsd:schema">
<jxb:schemaBindings>
<jxb:package name="mypackage.commonclasses"/>
</jxb:schemaBindings>
</jxb:bindings>
generatePackage does not really work well with multiple schemas.
And please file a bug in
https://java.net/jira/browse/MAVEN_JAXB2_PLUGIN
citing the problem with the multiple schemas and Eclipse. I'll take a look into it.

How to execute multiple cmd commands using maven?

I want to run multiple CMD commands in maven using single pom.xml.
May I know how can I do that?
for example
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.2.1</version>
<executions>
<execution>
<id>id1</id>
<phase>install</phase>
<goals>
<goal>exec</goal>
</goals>
<configuration>
<executable>cmd1</executable>
</configuration>
</execution>
<execution>
<id>id2</id>
<phase>install</phase>
<goals>
<goal>exec</goal>
</goals>
<configuration>
<executable>cmd2</executable>
</configuration>
</execution>
</executions> </plugin>

You could introduce two different profiles for cmd1 and cmd2.

Maybe exec-maven-plugin:
run a script that will run your cmds sequentially::
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.2</version>
<executions>
<execution>
<id>run a backup</id>
<phase>pre-integration-test</phase>
<goals>
<goal>exec</goal>
</goals>
<configuration>
<executable>/path/to/backup-script/bkp.sh</executable>
</configuration>
</execution>
</executions>
</plugin>
