### New feature, improvement proposal Hello, my understanding is that with `skipIfEmpty=true` will skip jar creation when src path does not exist or it does not contain any file. It would be usefull if the above option could be used to skip jar creation also when no files will be included. [example.zip](https://github.com/user-attachments/files/24235079/example.zip) In the attached example i have create the following possible use case: ``` example ├── module1 │ ├── pom.xml │ └── src │ ├── main │ │ └── java │ │ └── my │ │ └── org │ │ └── app1 │ │ └── App1.java │ └── test │ └── java │ └── my │ └── org │ └── app1 │ ├── App1Test.java │ └── junit │ ├── MyExtension.java │ └── MyExtensionTest.java ├── module2 │ ├── pom.xml │ └── src │ ├── main │ │ └── java │ │ └── my │ │ └── org │ │ └── app2 │ │ └── App2.java │ └── test │ └── java │ └── my │ └── org │ └── app2 │ └── App2Test.java └── pom.xml ``` where parent pom contains: ``` <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <version>3.5.0</version> <executions> <execution> <configuration> <classifier>junit</classifier> <skipIfEmpty>true</skipIfEmpty> <includes> <include>**/junit/*</include> </includes> <excludes> <exclude>**/*Test.class</exclude> </excludes> </configuration> <goals> <goal>test-jar</goal> </goals> </execution> </executions> </plugin> ``` In the above scenario I would expect that junit jar will be created only for app1, while now it is created also for app2 with only pom and manifest files ``` ❯ unzip -l module2/target/app2-1.0-junit.jar Archive: module2/target/app2-1.0-junit.jar Length Date Time Name --------- ---------- ----- ---- 0 2025-12-18 13:13 META-INF/ 81 2025-12-18 13:13 META-INF/MANIFEST.MF 0 2025-12-18 13:13 META-INF/maven/ 0 2025-12-18 13:13 META-INF/maven/my.org/ 0 2025-12-18 13:13 META-INF/maven/my.org/app2/ 515 2025-12-18 10:48 META-INF/maven/my.org/app2/pom.xml 43 2025-12-18 13:13 META-INF/maven/my.org/app2/pom.properties --------- ------- 639 7 files ``` -- This is an automated message from the Apache Git Service.
