Cumulative Error Reporting in Maven 3.0.5

Question

I am using the Maven multi-module project (more than 10 modules). I am trying to create a findbugs report of an entire module in one html page. Is there any way?

To create a separate report for each module I use below

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>findbugs-maven-plugin</artifactId>
    <version>3.0.0</version>
    <configuration>
        <!--
            Enables analysis which takes more memory but finds more bugs.
            If you run out of memory, changes the value of the effort element
            to 'Low'.
        -->
        <effort>Max</effort>
        <!-- Build doesn't fail if problems are found -->
        <failOnError>false</failOnError>
        <!-- Reports all bugs (other values are medium and max) -->
        <threshold>Low</threshold>
        <!-- Produces XML report -->
        <xmlOutput>false</xmlOutput>
        <skip>${skipFindbugs}</skip>
        <!-- Configures the directory in which the XML report is created -->
        <findbugsXmlOutputDirectory>${project.build.directory}/findbugs</findbugsXmlOutputDirectory>
    </configuration>
    <executions>
        <!--
            Ensures that FindBugs inspects source code when project is compiled.
        -->
        <execution>

            <phase>compile</phase>
            <goals>
                <goal>findbugs</goal>
            </goals>
        </execution>

                <!-- Selects the used stylesheet. -->

                <stylesheet>${project.parent.basedir}/default.xsl</stylesheet>

                <!--<stylesheet>fancy.xsl</stylesheet>-->
                <!--<stylesheet>summary.xsl</stylesheet>-->
                <fileMappers>
                    <!-- Configures the file extension of the output files. -->
                    <fileMapper implementation="org.codehaus.plexus.components.io.filemappers.FileExtensionMapper">

Answer 1

According to the official documentation of the plugin (question number 1), this is not possible.

However, here is the approach I used to achieve it:

• Add an add-on module to an existing multi-module project. This add-on will only be used for communication.
• Buildhelper Maven Plugin, . : , .
• Findbugs
• , Maven .
• : , , aggregator/parent, modules . , (.. , ), , .
