"report" goal of jacoco-maven-plugin stricly requires only exec file ( https://www.jacoco.org/jacoco/trunk/doc/report-mojo.html#dataFile ) and class files ( "project.build.outputDirectory" which is typically "target/classes" ) and doesn't strictly require presence of source files As a proof consider following example given src/main/java/Example.java class Example { } given src/test/java/ExampleTest.java public class ExampleTest { @org.junit.Test public void test() { new Example(); } } and given pom.xml <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd";> <modelVersion>4.0.0</modelVersion> <groupId>org.example</groupId> <artifactId>example</artifactId> <version>1.0-SNAPSHOT</version> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.jacoco</groupId> <artifactId>jacoco-maven-plugin</artifactId> <version>0.8.3</version> </plugin> </plugins> </build> </project> Execution of mvn jacoco:prepare-agent test without creation of report, will compile classes, execute tests and create exec-file target/jacoco.exec After removal of sources rm -rf src Execution of mvn jacoco:report will generate following report even in absence of source files [image: report.png] If maven plugin is not flexible enough for your use case, please consider usage of JaCoCo Ant Tasks ( https://www.jacoco.org/jacoco/trunk/doc/ant.html ) , e.g. via maven-antrun-plugin or JaCoCo Command Line Interface ( https://www.jacoco.org/jacoco/trunk/doc/cli.html ) Regards, Evgeny -- You received this message because you are subscribed to the Google Groups "JaCoCo and EclEmma Users" group.
