generatePom=false not working with 3.0.0-M1

Steps to reproduce:

mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4 -DgroupId=test1 -DartifactId=test1 -Dversion=1.0-SNAPSHOT

mvn clean package install:install-file -Dfile=target/test1-1.0-SNAPSHOT.jar -DgeneratePom=false

produces:

[INFO] — maven-install-plugin:2.5.2:install-file (default-cli) @ test1 —
[INFO] Installing D:\Workarea\sample\test1\target\test1-1.0-SNAPSHOT.jar to C:\Users\xxx\.m2\repository\test1\test1\1.0-SNAPSHOT\test1-1.0-SNAPSHOT.jar
[INFO] ------------------------------------------------------------------------

changing the version of the maven-install-plugin in pom.xml to 

<plugin>
{{ <artifactId>maven-install-plugin</artifactId>}}
{{ <version>3.0.0-M1</version>}}
{{ </plugin>}}

the same call to

mvn clean package install:install-file -Dfile=target/test1-1.0-SNAPSHOT.jar -DgeneratePom=false

produces:

[INFO] — maven-install-plugin:3.0.0-M1:install-file (default-cli) @ test1 —
[INFO] Installing D:\Workarea\sample\test1\target\test1-1.0-SNAPSHOT.jar to C:\Users\xxx\.m2\repository\test1\test1\1.0-SNAPSHOT\test1-1.0-SNAPSHOT.jar

Which also installs a POM - which is not what we want!
