Unable to generate the coverage report(No license file found) Edited

Venkataramana Reddy Jul 25, 2017


After generating the new .db files i have used the below command to generate the HTML report for coverage.

java -cp clover.jar com.atlassian.clover.reporters.html.HtmlReporter -i clover.db -o clover_html

Then i'm getting the below error.

C:\Users\xxxxxx\workspace\codeCoverage\webappclover\target\clover>java -cp clover.jar com.atlassian.clover.reporters.html.HtmlReporter -i clover.db -o clover_html
Clover Version 4.0.6, built on September 18 2015 (build-964)
Loaded from: C:\Users\xxxxx\workspace\codeCoverage\webappclover\target\clover\clover.jar
ERROR: No license file found.
Exception in thread "main" java.lang.RuntimeException: Invalid or missing License.. Please visit to obtain a valid license.
at com.atlassian.clover.CloverStartup.loadLicense(
at com.atlassian.clover.CloverStartup.loadLicense(
at com.atlassian.clover.reporters.CloverReporter.loadLicense(
at com.atlassian.clover.reporters.html.HtmlReporter.main(

currently i'm using clover 4.0.6 version for maven.

For reference i am adding the steps, what i have followed for generating the .db files

1) I have added the clover plugin 4.0.6 to maven and compiled my application using the "mvn clover2:instrument" to generate the instrument code.

2)Added the clover-4.0.6.jar in tomcat classpath.

2) Also added the clover.db files location in catalina.bat like this

set "JAVA_OPTS=%JAVA_OPTS% -Djava.protocol.handler.pkgs=org.apache.catalina.webresources -Dclover.initstring.basedir=C:\Users\xxxxx\workspace\codeCoverage\webapplication\target\clover" 

3) And deployed the instrument code(war) in tomat server and ran the application and tested it.

4) new .db files got generated.

then i have tried to generate a report from them and i got that No license file found Error.


can you please guide me how to add that clover license information to Maven and generate the reports from .dm files.

Please note that you are using Clover version 4.0.6, which is a commercial version of Clover built in 2015. As such it requires a license key. In case you have purchased Clover, visit to download your license key. Next you can pass a path the license key using a <licenseLocation> configuration option. 

In case your intention was to use an open-sourced version of Clover, as it was announced in this blog post, you have to checkout the source repository and compile binaries from sources, as described in the developer guide.

You may also be interested in using open-sourced Clover versions developed by the community, see the "Forks" dialog in the Bitbucket repository.
