Coverage report is generating for a springboot + maven project, but there is an NPE

[Ruhshan]

Hello,

I have just added kover with my spring boot project. I can run tests and also generate coverage reports. But there is this NPE:

Though the coverage is generated. Can you please tell me I'm doing something wrong? Or what could resolve this.

Here is a minimal project that generates this issue:

Hi,
thanks for the report and the reproducer!

To workaround this bug you may add empty sourceDirs element to the kotlin-maven-plugin configuration.
Like

            <plugin>
                <groupId>org.jetbrains.kotlin</groupId>
                <artifactId>kotlin-maven-plugin</artifactId>
                <configuration>
                    <args>
                        <arg>-Xjsr305=strict</arg>
                    </args>
                    <compilerPlugins>
                        <plugin>spring</plugin>
                    </compilerPlugins>
                    <sourceDirs></sourceDirs> <!-- fix Kover NPE -->
                </configuration>
