I defined a custom property name for the JaCoCo agent but the prepare-agent goal doesn't update the value of the custom property if it is already defined.
In my example below, the name of the custom property is coverageAgent. The surefire plug-in is then configured to use the coverageAgent property as its argument line. When surefire runs, its argument line doesn't contain the JaCoCo agent configuration. ----------------------------------------- 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/xsd/maven-4.0.0.xsd";> <modelVersion>4.0.0</modelVersion> <groupId>com.somecompany.bdo</groupId> <artifactId>bdo</artifactId> <version>1.0-SNAPSHOT</version> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <jacoco.propertyName>coverageAgent</jacoco.propertyName> <coverageAgent/> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.jacoco</groupId> <artifactId>jacoco-maven-plugin</artifactId> <version>0.8.0</version> <executions> <execution> <id>jacoco-prepare-agent</id> <goals> <goal>prepare-agent</goal> </goals> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.20.1</version> <configuration> <argLine>${coverageAgent}</argLine> </configuration> </plugin> </plugins> </build> </project> ----------------------------------------- Maven output ----------------------------------------- mvn -X clean test ...
