Witold Markowski commented on MINSTALL-156:
-------------------------------------------
This behavior may be an expected behavior. It looks like *3.0.0-M1* will
install *pom* file always, if the *pom* is available from the inside of the
installed *jar* file. When the artifact is built by Maven, it will put the
*pom* in the *META-INF* directory inside of the jar. This *pom* file will be
installed always no matter what *generatePom* says.
However *generatePom* comes into action when you want to install a *jar* file
which doesn't contain any *META-INF* inside. [~robert12345], please do a simple
test:
* delete whole *META-INF* from the inside of your
*target/test1-1.0-SNAPSHOT.jar*
* execute *mvn
org.apache.maven.plugins:maven-install-plugin:3.0.0-M1:install-file
-Dfile=target/test1-1.0-SNAPSHOT.jar -DgroupId=test1 -DartifactId=test1
-Dversion=1.0-SNAPSHOT -Dpackaging=jar -Dgene ratePom=false*
In my test *pom* file is not generated by *maven-install-plugin* as below:

$ mvn org.apache.maven.plugins:maven-install-plugin:3.0.0-M1:install-file
-Dfile=target/test1-1.0-SNAPSHOT.jar -DgroupId=test1 -DartifactId=test1
-Dversion=1.0-SNAPSHOT -Dpackaging=jar -Dgene ratePom=false

>From the other hand, this behavior may break the back compatibility with
>*2.5.2* version, where it was possible to *NOT* to install *pom*. The question
