Jacoco - Enhancement to dump jacoco.exec from more than one host in a single maven command

[manmo...@gmail.com]

Hello,

I would like to dump jacoco exec file from different hostnames and merge it to a single file to generate report in a single maven command. Can you add a list of string type for accepting more than one host name so that i can pass multiple host names to dump goal to download the exec files from more than one hosts?

For example,

mvn -Djacoco.address=192.162.1.1,192.162.1.2 -Djacoco.port=9100 jacoco:dump jacoco:report

Above command wouldn't work because you can pass only one hostname which is a string type.

I'm not sure who implemented the jacoco maven plug-in. Let me know if you know the contact or if i'm not posting this to the right forum

Btw, jacoco is an excellant tool.

Thanks

Hi ManMohan,

I see more scenarios here:

* Mutiple VMs running on the same host on different ports
* Combination of both

So I wonder whether the proposed change helps in a specific use case
only. Alternatively you can configure multiple executions or wrap a
script around the mvn call. The current dump goal already appends the
data to a single *.exec file if appens=true (whch is default).

Cheers,

ya, i'm planning to use "dump" goal and use appends=true to pull the data from multiple hostnames. Thanks for the details. Also to use reset if i would want to reset the counter.

Thanks

Hi Team,

I have three hosts and I need to capture the code coverage results 

<plugin>

                <groupId>org.jacoco</groupId>

                <artifactId>jacoco-maven-plugin</artifactId>

                <version>0.7.4.201502262128</version>

                <configuration>

                    <destFile>${basedir}/target/coverage-reports/jacoco-it.exec</destFile>

                    <dataFile>${basedir}/target/coverage-reports/jacoco-it.exec</dataFile>

                    <outputDirectory>${project.reporting.outputDirectory}/jacoco-it</outputDirectory>

                </configuration>

                <executions>

                    <execution>

                        <id>dump</id>

                        <phase>post-integration-test</phase>

                        <goals>

                            <goal>dump</goal>

                        </goals>

                        <configuration>

                            <address>192.162.1.1,192.162.1.2,192.162.1.3</address>

                            <port>6300</port>

                            <dump>true</dump>

                        </configuration>

                    </execution>

                    <execution>

                        <id>default-report-integration</id>

                        <goals>

                            <goal>report-integration</goal>

                        </goals>

                    </execution>

                </executions>

            </plugin>

This is not working. Please provide solution to solve this

Thanks,

You have to add goal merge so that the dumped files are merged and then generate report on the merged file.
