I have following configuration in my pom.xml, I am still seeing that a multiple clover.db files are getting generated in each modules target folder. Am I missing something?
<profile> <id>clover</id> <activation> <property> <name>clover_property</name> <value>true</value> </property> </activation> <build> <plugins> <plugin> <groupId>com.atlassian.maven.plugins</groupId> <artifactId>maven-clover2-plugin</artifactId> <version>3.1.3</version> <configuration> <licenseLocation>C:\clover\clover.license</licenseLocation> <generateHtml>true</generateHtml> <generateXml>true</generateXml> <numThreads>0</numThreads> <coverageCacheSize>128m</coverageCacheSize> <singleCloverDatabase>true</singleCloverDatabase> <cloverDatabase>C:\clover\clover.db</cloverDatabase> </configuration> </plugin> </plugins> </build> </profile>
If true, then a single cloverDatabase will be used for the entire project. This flag will be ignored if a custom cloverDatabase location is specified.
You have the following options:
1) Keep the <singleCloverDatabase>true</singleCloverDatabase> and remove the <cloverDatabase> tag. Database will be written to the /target/clover folder inside the last Maven module compiled.
2) Remove the <singleCloverDatabase> tag and keep the <cloverDatabase> tag with an absolute path declared in it. When instrumenting subsequent modules, Clover will update the same database file as the path is absolute. However, this may have a performance impact if you have have many modules (like few hundreds) and a lot of unit tests (like one thousand or more). This is because a number of coverage recording files created on disk will be roughly equal to: number of clover.db updates * number of tests.
3) Remove the <singleCloverDatabase> and the <cloverDatabase> tags. Instead of this, declare the <mergedCloverDatabase> and call clover2:aggregate at the end of the build (typically after a testing phase), but before report generation. For instance:
mvn clean clover2:setup test clover2:aggregate clover2:clover
