I did some more testing and I noticed this: $ cat <<EOF >pom.xml <project> <modelVersion>4.0.0</modelVersion> <groupId>org.fedoraproject.xmvn.it</groupId> <artifactId>rhbz1012059</artifactId> <version>1.0.0-SNAPSHOT</version> <packaging>jar</packaging> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <executions> <execution> <id>war</id> <phase>package</phase> <goals> <goal>war</goal> </goals> </execution> </executions> </plugin> </plugins> </build> </project> EOF $ mkdir -p src/main/webapp/WEB-INF $ touch src/main/webapp/WEB-INF/web.xml $ mvn clean install Result: [INFO] Installing /tmp/jar-plugin/target/rhbz1012059-1.0.0-SNAPSHOT.war to /home/msrb/.m2/repository/org/fedoraproject/xmvn/it/rhbz1012059/1.0.0-SNAPSHOT/rhbz1012059-1.0.0-SNAPSHOT.jar So maven-war-plugin behaves the same. This makes me believe that this is expected behavior for plugins commonly used during package phase. Note you can change project's configuration to get desired result. From my POV it's not a bug.
