# MiniMaven

MiniMaven is a minimal build and dependency management system. It reads project configurations in the same format as Maven (pom.xml files).

## Why Maven?

In the Fiji project, we need an easy way to define projects and their dependencies. We also want to support the widest variety of development tools, such as IntelliJ, Netbeans or Eclipse.

Maven is a standard way to do exactly that.

## Why MiniMaven?

The only reason for MiniMaven to exist is that Maven – while powerful – is also pretty resource-hungry. In contrast to MiniMaven, Maven requires many more CPU cycles, takes longer, and downloads many more bytes (due to downloading and running requiring Maven plugins and their dependencies).

Therefore we needed a system to build ImageJ1, ImageJ2 and Fiji quickly from the same type of project description files as Maven interprets, to be maximally flexible and interoperable.

## Command-line options

MiniMaven can be called via the main class org.scijava.minimaven.MiniMaven. Just like real Maven, you can start it directly in the directory:

ImageJ-<platform> --mini-maven <command>


To get a list of supported commands, use the command help.

By default, MiniMaven will build the project specified by the pom.xml file in the current directory, recursing if it is an aggregate project. However, you can ask MiniMaven to look for a specific artifactId in an aggregate project’s tree:

ImageJ-<platform> --mini-maven -DartifactId=<artifactId> <command>


MiniMaven also heeds these properties:

• minimaven.offline: do not try to connect to remote Maven repositories
• minimaven.updateinterval: minimum age (in seconds) of a -SNAPSHOT artifact for MiniMaven to look for a newer one
• mainClass: used with the run command to override or set the main class to execute
