如何避免在Maven中出现空的测试JAR?

skipIfEmpty does the trick ,很荣幸 wemu

        <plugin>
            <!-- generate test-jar artifacts for creating test-test dependencies 
                across modules -->
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <executions>
                <execution>
                    <goals>
                        <goal>test-jar</goal>
                    </goals>

                    <configuration>
                        <skipIfEmpty>true</skipIfEmpty>
                    </configuration>
                </execution>
            </executions>
        </plugin>
