JaCoCo tests run on a jar file from pom.xml

I am trying to get the coverage of a few test cases related to an open source project of which I got the jar file.
I'm using maven as automatic build tool and the jacoco plugin for maven to get the coverage of the tests on the project.
What I would like to achieve is the same output that I can get with the command:
-jar jacococli.jar report jacoco.exec \
--classfiles <project.jar> \
--sourcefiles <myTestsDirectory> \
--html <jacocoReportsDirectory> \
--xml <jacocoReportsDirectory>coverageFile.xml \
--csv <jacocoReportsDirectory>coverageFile.csv
When I run this from the commandline I can retrieve the report for the coverage computed on the whole project (the jar).
I don't know how to insert this command (or something that can get me the same output) in the pom. I tried to put it in the surefire plugin argLine (with the -javaagent command) but this got me nowhere.
This is where I got so far:
<build>
<sourceDirectory>src</sourceDirectory>
<testSourceDirectory>src/test</testSourceDirectory>
<plugins>

</argLine>
<reportsDirectory>target/coverage-reports/surefire-reports</reportsDirectory>
</configuration>
</plugin>
</plugins>
</build>
Giving the whole src directory as the sourceDirectory gets my test cases as the target of the coverage computation and I don't want that.
Note: there are no java classes in src to which the tests are targeted, so there's no need to put that as sourceDirectory. I assume this has to point to the jar somehow.

Jacoco Maven coverage report always 0%

I've this problem with Jacoco maven plugin in IntelliJ IDEA 2020.
I put the Jacoco plugin configuration in my pom.xml maven file and then executed the mvn clean install command. It generates the target\site folder but when I open the index.html file it shows me a coverage of 0%, listing all my classes, although I get a 92% coverage in IntelliJ's integrated tool. The jacoco.exec file is generated in target folder, but it's empty!
How can I fix this issue?
Here's my pom.xml fragment:
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>14</source>

I'm using the latest Java version (14).
Thanks in advance!

Unit tests getting executed during integration test phase even after excluding them

I have a a unit test (ProductDaoTest.java) and an integration test (ProductDaoIT.java) in my maven application.
I would like to execute only the integration test during the mvn verify command call but the unit test also gets executed even after excluding it using the <exclude> tag in the maven-failsafe-plugin configuration.
How can I fix this problem?

In Maven, test step is before verify step in the lifecycle.
So it you don't skip this step, it is bound to execute.
If you want to skip test , either use -Dmaven.test.skip=tr‌​ue as khmarbaise suggested, either create a dedicated Maven profile for IT where you will ignore unit-tests in this way :
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<skipTests>true</skipTests>
</configuration>
</plugin>
Generally, you create a Maven profile for integration tests, so if it is the case, gathering all the configuration in a place is better that scattering it.

How to execute a plugin explicitly after a certain phase in maven?

I'm using javafx-maven plugin to create a javafx webstart application. I had some issues signing the jar files with the javafx-maven plugin. what I want to do is, package(jar) the application with javafx-maven plugin and then sign the jar files using maven-jarsigner-plugin .
How do i execute the maven-jarsigner-plugin to sign my files after the application is packaged?
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jarsigner-plugin</artifactId>
<version>1.4</version>
<executions>
<execution>
<goals>
<goal>sign</goal>
</goals>
</execution>
</executions>
<configuration>
<archiveDirectory>target/jfx/app/</archiveDirectory>
<includes>
<include>**/*.jar</include>
</includes>
<keystore>path tp keystore</keystore>
<alias>alias</alias>
<storepass>password</storepass>
<keypass>password</keypass>
</configuration>
</plugin>
<plugin>
<groupId>com.zenjava</groupId>
<artifactId>javafx-maven-plugin</artifactId>
<version>8.3.0</version>
<configuration>
<bundler>jnlp</bundler>
<mainClass>com.myorg.myapp.launcher.myappLauncher</mainClass>
<bundleArguments>
<jnlp.allPermisions>true</jnlp.allPermisions>
<jnlp.includeDT>true</jnlp.includeDT>
<jnlp.outfile>myapp</jnlp.outfile>
</bundleArguments>
</configuration>
</plugin>

To workaround this I moved signing to verify phase.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jarsigner-plugin</artifactId>
<version>1.4</version>
<executions>
<execution>
<id>signing</id>
<goals>
<goal>sign</goal>
<goal>verify</goal>
</goals>
<phase>verify</phase>
<inherited>true</inherited>
<configuration>
...
</configuration>
</execution>
</executions>
</plugin>
Then I invoke maven like this:
mvn verify
Or make verify your default goal
Alternatively you can move javafx-maven plugin to the "prepare-package" phase:
<plugin>
<groupId>com.zenjava</groupId>
<artifactId>javafx-maven-plugin</artifactId>
<version>8.1.0</version>
<configuration>
<bundler>jnlp</bundler>
<mainClass>com.myorg.myapp.launcher.myappLauncher</mainClass>
<bundleArguments>
<jnlp.allPermisions>true</jnlp.allPermisions>
<jnlp.includeDT>true</jnlp.includeDT>
<jnlp.outfile>myapp</jnlp.outfile>
</bundleArguments>
</configuration>
<executions>
<execution>
<id>create-jfxjar</id>
<phase>prepare-package</phase>
<goals>
<goal>build-jar</goal>
</goals>
</execution>
</executions>
</plugin>

Failure to execute maven goal with Jacoco

And the output:

And the output depends of version jacoco.
Do you have any ideas?

I suspect you are running a specific goal of jacoco (the check goal to be specific), meaning you are not running any specific phase of any lifecycle.
Like:
mvn jacoco:check
Note that your execution enforce-distribution-size is bound to the verify phase of the default lifecycle - so, if you want the execution enforce-distribution-size to occur, you should either:
run with a phase that is at least verify (I assume you don't want to do this) or
rename the <id> of that <execution> to default-cli (see this), if you require a maven run with specific jacoco goal to work, say the check goal. Like, change the following line:
<id>enforce-distribution-size</id>
to
<id>default-cli</id>
That's all you'll need to do.
