jacoco is not picking up the report path correctly

Question

Our report generation was working fine before we made some changes. Now, I am not at all able to make it work, I have tried all solutions which I can find.

This is our older code :

           <plugin>
            <artifactId>maven-surefire-plugin</artifactId>
            <executions>
                <execution>
                    <phase>integration-test</phase>
                    <goals>
                        <goal>test</goal>
                    </goals>
                    <configuration>
                        <excludes>
                            <exclude>none</exclude>
                        </excludes>
                        <includes>
                            <include>**/*IntegrationTest</include>
                        </includes>
                    </configuration>
                </execution>
            </executions>
        </plugin>
       <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <version>0.8.8</version>
            <executions>
                <execution>
                    <goals>
                        <goal>prepare-agent</goal>
                    </goals>
                </execution>
                <execution>
                    <id>generate-code-coverage-report</id>
                    <phase>test</phase>
                    <goals>
                        <goal>report</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

Now, we have changed it to below code :

           <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
                <forkCount>1</forkCount>
                <reuseForks>true</reuseForks>
                <argLine>-Xmx1024m</argLine>
            </configuration>
            <executions>
                <execution>
                    <phase>integration-test</phase>
                    <goals>
                        <goal>test</goal>
                    </goals>
                    <configuration>
                        <excludes>
                            <exclude>none</exclude>
                        </excludes>
                        <includes>
                            <include>**/*IntegrationTest</include>
                        </includes>
                    </configuration>
                </execution>
            </executions>
        </plugin>
        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <version>0.8.8</version>
            <executions>
                <execution>
                    <goals>
                        <goal>prepare-agent</goal>
                    </goals>
                </execution>
                <execution>
                    <id>generate-code-coverage-report</id>
                    <phase>test</phase>
                    <goals>
                        <goal>report</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

As you can see, we have added some configuration, and as per my extensive search for issues, the only hint which I got is to update the argline to below code

<argLine>${argLine} -Xmx1024m</argLine>

but now I get the below error :

java.io.FileNotFoundException: /app2/azdosagents/agent3/_work/21029/s/CCReport43F6D5EF/jacoco.exec (No such file or directory)
at java.base/java.io.FileOutputStream.open0(Native Method)
at java.base/java.io.FileOutputStream.open(FileOutputStream.java:298)
at java.base/java.io.FileOutputStream.<init>(FileOutputStream.java:237)

at org.jacoco.agent.rt.internal_035b120.Agent$1.run(Agent.java:54)

Now, what I see is previously jacoco was picking up the directories correctly, It was storing the jacoco in target/jacoco.exec. but now it picks up a location which doesnot even exists.

I have spend a day in this, but still no luck. any leads would be appreciated.

Try by using the parent jacoco version and using the default arguments.
