Jacoco report aggregate shows 0 coverage even if tests were executed - integration-testing

My maven project directory structure is as follows:
parent
-child
-src/java
-src/test <!-- unit tests -->
-pom.xml
-integration_test
-src/test
-pom.xml
-report
-pom.xml
-pom.xml
Since integration tests and source code are in different modules I used Jacoco report-aggragate (report module).

The unit tests code coverage report is displayed correctly, but for integration tests even though the tests are executed, the code coverage is given as 0

How to use a custom response class instead of using the spring default ResponseEntity

I am using openapi-generator-maven-plugin for generating the classes. Using the following dependency
<build>
<plugins>
<plugin>
<groupId>org.openapitools</groupId>
<artifactId>openapi-generator-maven-plugin</artifactId>
<version>4.0.3</version>
<executions>

<inputSpec>${swagger.gen.product.componentsYaml}</inputSpec>
<generatorName>spring</generatorName>
<modelPackage>${swagger.gen.srcPackage}.model</modelPackage>
<apiPackage>${swagger.gen.srcPackage}.api.controller</apiPackage>
<configOptions>
<interfaceOnly>true</interfaceOnly>
<sourceFolder>src/main/java</sourceFolder>

</configuration>
</execution>
</executions>
</plugin>
<plugin>
<artifactId>maven-jar-plugin</artifactId>
</plugin>
</plugins>
</build>
The java api generating have the return type org.springframework.http.ResponseEntity.
Instead of using the default response type I want
to use a custom one. Is there any way to implement this?

The issue appears to be resolved now. Please try again.
According to this blog post, it looks like DynamoDB Local is now available in AWS Maven Repo. So you should simply substitute the <repository> node in your pom.xml with something like:
<repository>
<id>dynamodb-local</id>
<name>DynamoDB Local Release Repository</name>
<url>https://s3-us-west-2.amazonaws.com/dynamodb-local/release</url>
</repository>
Hope it helps.
In August 2018 Amazon announced new Docker image with Amazon DynamoDB Local onboard. It does not require downloading and running any JARs as well as adding using third-party OS-specific binaries like sqlite4java.
It is as simple as starting a Docker container before the tests:
docker run -p 8000:8000 amazon/dynamodb-local
You can do that manually for local development, as described above, or use it in your CI pipeline. Many CI services provide an ability to start additional containers during the pipeline that can provide dependencies for your tests. Here is an example for Gitlab CI/CD:
test:
stage: test
image: openjdk:8-alpine
services:
- name: amazon/dynamodb-local
alias: dynamodb-local
script:
- DYNAMODB_LOCAL_URL=http://dynamodb-local:8000 ./gradlew clean test
So, during the test task DynamoDB will be available on http://dynamodb-local:8000.
Another, more powerful tool is localstack. It supports two dozen of AWS services, DynamoDB is one of them. The isage is very similar, you have to start it before running the tests and it will expose AWS-compatible APIs on given ports:
test:
stage: test
image: openjdk:8-alpine
services:
- name: localstack/localstack
alias: localstack
script:
- ./gradlew clean test
Aaahhh! yes, i have resolve it making changes in pom file like this
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>DynamoDBLocal</artifactId>
<version>1.11.0.1</version>
</dependency>
instead of
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>DynamoDBLocal</artifactId>
<version>${aws.java.sdk.version}</version>
</dependency>

Any Help?
adding the following code in arquillian.xml works for me:
<extension qualifier="jacoco">
<property name="includes">com.your.top.package.*</property>
</extension>
indeed only your classes will be used in instrumentation

How to copy local jars in Maven when building JavaFX executable?

I finally got Maven to build a JavaFX executable jar with this pom:
<dependencies>
<dependency>
<groupId>commons-configuration</groupId>
<artifactId>commons-configuration</artifactId>
<version>1.7</version>
</dependency>
<dependency>
<groupId>net.sf.opencsv</groupId>
<artifactId>opencsv</artifactId>
<version>2.0</version>
</dependency>
<dependency>
<groupId>ProtocolAnalyzer</groupId>
<artifactId>com.protocolanalyzer.api</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>${project.basedir}/libs/Protocol-decoder.jar</systemPath>
</dependency>
<dependency>
<groupId>ProtocolAnalyzer</groupId>
<artifactId>bluecove</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>${project.basedir}/libs/bluecove-2.1.1-SNAPSHOT.jar</systemPath>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>com.zenjava</groupId>
<artifactId>javafx-maven-plugin</artifactId>
<version>8.1.1</version>
<configuration>
<mainClass>com.andres.multiwork.pc.Main</mainClass>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.5.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
This works perfectly: I get an executable jar and a lib folder in the same directory of my jar where all the libraries are copied.
But I have two local jars (Protocol-decoder.jar and bluecove-2.1.1-SNAPSHOT.jar) that I added as dependencies. However, they are not being copied to the lib folder or being added in the classpath in the manifest inside the jar.
I'm new to Maven but I think that maven-resources-plugin is the plugin that copies the dependencies to the lib folder. How I can tell Maven or the plugin to also copy my local dependencies. Is this possible without creating a local Maven repository and adding my jars there?
You are looking for maven-dependency-plugin, goal copy-dependencies.
<plugin>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>

</execution>
</executions>

When running your Jar with java -jar, you're no longer running with the maven resolving of dependencies. You have to make sure that all the jars you depend on are available at the relative loacation specificied in the MANIFEST.mf file in your Jar. Usually, you would use the assembly plugin to create a distributable archive that creates this structure. Or you could use a uberjar/onejar plugin to included everything inside your Jar.
You have 2 options to fix this:
Option 1 - use both plugins below to copy dependencies to a "lib" folder (see outputDirectory) and make your Runnable JAR know where they are (see classpathPrefix)
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<mainClass>example.MyMainClass</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>false</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
</executions>
Option 2 - Use maven-assembly-plugin to create a single JAR with all dependencies included. (all dependencies are extracted and compressed together in the same JAR)
<assembly
xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0 http://maven.apache.org/xsd/assembly-1.1.0.xsd">
<id>with-dependencies</id>
<formats>
<format>jar</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<dependencySets>
<dependencySet>
<outputDirectory>/</outputDirectory>
<useProjectArtifact>true</useProjectArtifact>
<unpack>true</unpack>
<scope>compile</scope>
</dependencySet>
</dependencySets>
I've seen the problem, too. Cobertura creates instrumented copies of all compiled classfiles (in target/classes) by bytecode manipulation. My jar file contained the instrumented class files (from target/generated-classes/cobertura), but cobertura.jar was missing. So, ClassNotFoundException was the right reaction.
However, since my POM doesn't contain any hint, which are the intended classes for packaging, Maven has the free choice ... and it uses the instrumented set of files.
My solution was really simple: mvn clean and mvn package. The first call removes all instrumented classes. Then, the second call finds only the uninstrumented classes without any external references to Cobertura.
