Can't generate jacoco.exec file

I have project with Mockito and TestNG tests. I want to see coverage in Sonarqube. For this I should have jacoco.exec file. When I try to build my project, in result I have "BUILD SUCCESS" without jacoco.exec file in target folder.
There is part of my pom.xml file.
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.8.6</version>
<executions>
<execution>
<id>prepare-agent</id>
<goals>
<goal>prepare-agent</goal>
</goals>
</execution>
<execution>
<id>report</id>
<goals>
<goal>report-aggregate</goal>
</goals>
<phase>verify</phase>
</execution>
</executions>
</plugin>
...
command to start build:
mvn clean install sonar:sonar -Dsonar.projectKey=number20 -Dsonar.host.url=http://localhost:9000 -Dsonar.login=**mylogin**

Your configuration hasn't the report execution goal and in addition to this you should not use jacoco exec file because it's deprecated. You should configure the sonar jacoco plugin as suggested in this official example.
<build>
<plugins>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.8.7</version>
<executions>
<execution>
<id>prepare-agent</id>
<goals>
<goal>prepare-agent</goal>
</goals>
</execution>
<execution>
<id>report</id>
<goals>
<goal>report</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
And then jacoco report, generated in the default path, will be imported by sonar.

why do I not find generated source files for grpc and protobuf when using maven and java in vscode

I have a pom file that correctly generates the grpc and protobuf source files I need in target/generated-sources when run from the command line. But when I build in vscode those directories are empty and references to the protobufs are undefined. Here's the section of my pom file that builds the grpc source.
<plugin>
<groupId>org.xolstice.maven.plugins</groupId>
<artifactId>protobuf-maven-plugin</artifactId>
<version>0.5.0</version>
<configuration>
<protocArtifact>com.google.protobuf:protoc:3.2.0:exe:${os.detected.classifier}</protocArtifact>
<pluginId>grpc-java</pluginId>
<pluginArtifact>io.grpc:protoc-gen-grpc-java:${grpc.version}:exe:${os.detected.classifier}</pluginArtifact>
</configuration>
<executions>
<execution>
<goals>
<goal>compile</goal>
<goal>compile-custom</goal>
</goals>
</execution>
</executions>
</plugin>
I added the following based on what I read in other posts to prevent vscode/eclipse from removing the generated source directories
<plugin>
<groupId>org.xolstice.maven.plugins</groupId>
<artifactId>protobuf-maven-plugin</artifactId>
</plugin>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<executions>
<execution>
<id>add-source</id>
<phase>generate-sources</phase>
<goals>
<goal>add-source</goal>
</goals>
<configuration>
<sources>
<source>target/generated-sources/protobuf/grpc-java</source>
<source>/target/generated-sources/protobuf/java</source>
</sources>
</configuration>
</execution>
</executions>
</plugin>
When vs-code builds, the target generated-source directories are there, but there is no source in them. We had a similar problem with intellij but were able to work around it by running the maven command line build before opening intellij but that does not seem to work for vscode.

Use protoc-jar-maven-plugin instead.
Sample usage please view protoc-jar-maven-plugin.

Add generated Apache Avro source with build-helper-maven-plugin

I'm using Apache avro to generate some pojos, all work very well in run, expect that the generated source is marked as inexistent in imports on IDE (intellij) .
I tried to use build-helper-maven-plugin to add source, but it doesn't work
this is my maven configuration for apache avro and build helper plugins :
<plugin>
<groupId>org.apache.avro</groupId>
<artifactId>avro-maven-plugin</artifactId>
<version>${avro.version}</version>
<configuration>
<stringType>String</stringType>
</configuration>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>schema</goal>
</goals>
<configuration>
<sourceDirectory>${project.basedir}/src/main/avro/</sourceDirectory>
<outputDirectory>${project.build.directory}/generated-sources/</outputDirectory>
<imports>
<import>${project.basedir}/src/main/avro/errorkind.avsc</import>
</imports>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>3.2.0</version>
<executions>
<execution>
<id>add-source</id>
<phase>generate-sources</phase>
<goals>
<goal>add-source</goal>
</goals>
<configuration>
<sources>
<source>${project.build.directory}/generated-sources</source>
</sources>
</configuration>
</execution>
</executions>
</plugin>

Try changing your pom with following and run clean install and then you should be able to import.
<configuration>
<sourceDirectory>${project.basedir}/src/main/resources/</sourceDirectory>
<source>${project.build.directory}/generated-sources</source>
</configuration>
In POM InteliJ may give you a fake error after adding this but your build will success.

"generated-sources" reside under ${project.build.directory}/target folder
Also, try marking "generated-sources" as source directory. You can do that by:
Project Structure → Modules → Click the generated-sources folder and make it a sources folder.

How to get PMD maven plugin to skip generated source code?

So I'm creating a maven plugin using the maven-plugin-plugin. The HelpMojo in maven-plugin-plugin generates a java source file.
Unfortunately, PMD is picking this up and complaining about it. Is there a way to have PMD ignore just a single source file? Thanks!
Maven PMD Configuration:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-pmd-plugin</artifactId>
<executions>
<execution>
<id>pmd-verify</id>
<goals>
<goal>check</goal>
<goal>cpd-check</goal>
</goals>
<configuration>
<printFailingErrors>true</printFailingErrors>
</configuration>
</execution>
</executions>
</plugin>

Generated sources usually end up (with maven) in a subdirectory in target/generated-sources, for the maven-plugin-plugin it's target/generated-sources/plugin.
You can exclude these complete directories with excludeRoots, e.g.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-pmd-plugin</artifactId>
<executions>
<execution>
<id>pmd-verify</id>
<goals>
<goal>check</goal>
<goal>cpd-check</goal>
</goals>
<configuration>
<printFailingErrors>true</printFailingErrors>
<excludeRoots>
<excludeRoot>target/generated-sources/plugin</excludeRoot>
</excludeRoots>
</configuration>
</execution>
</executions>
</plugin>
There is also a file based exclude option.

Jenkins and Jacoco Integration Test Coverage

I just added Jacoco on my maven dependencies to run integration tests. Then, I created an integration test to test my controller. For example, I tested my HTTP response codes, the headers and the response resources. After that, I created a profile on maven that starts an embedded tomcat. So, everytime I want to run my integration tests, I just put the profile on the maven goals. However, when I execute the build on Jenkins and Sonar reads the reports from Jacoco, the reports says that I have not tested my controller. The question is: How I tell Jacoco that I have passed through my Controllers, Services and Repositories?
Thanks to all!

Are you getting any Integration Coverage, or just 0%?
It can be quite tricky to set up Integration Test Coverage using maven and Sonar.
Check there is a jacoco file produced when the IT tests are run.
Check your POM set up compared to this...
