StreamBase Studio uses the Maven project format provided by Eclipse. Maven is a software build and management system aimed primarily at Java developers, but adapted by TIBCO to develop EventFlow and LiveView fragments as well.
StreamBase Studio projects are in Maven project format, and all projects are built and run under Maven control. Thecontext menu includes several Maven commands and goals.
Using Maven provides a well-known, thoroughly documented, and standard way to specify project dependencies, both within and external to the project. Maven automatically configures search paths for code in specified dependencies, and also manages resource search paths automatically.
The Maven system assumes that each product produces an artifact as the output of its build. The artifact produced by a
standard Java project is usually a JAR file. The artifact produced by a StreamBase
EventFlow project is an EventFlow fragment archive. This
.zip file that contains your EventFlow modules and
resources in runnable format.
Likewise, the artifact produced by a LiveView project is a LiveView fragment archive.
When Maven is run, it follows the directions in the project's Project Object Model, which is defined in an XML file at the root of each
project folder named
pom.xml. The StreamBase POM files
can be run both in Studio and at the command prompt with the mvn command, if your system has a recent
installation of command-line Maven installed.
The Maven POM defines a fixed lifecycle for the stages of building an EventFlow project. You can specify any stage as a goal when you run Maven. This automatically runs all defined stages prior to the specified goal. For a project in good shape, you only need to specify the two goals clean install, which runs all the stages of cleaning your project folder, then runs all the stages of compiling, packaging, verifying, and unit-testing your project before running the install stage.
For StreamBase projects, the install
goal means that an EventFlow fragment archive for your project is generated and
copied into your project's
target folder. The goal goes
on to copy that file to your local Maven repository. Likewise for LiveView projects,
the install goal means to generate a
LiveView fragment archive file in the
and to then copy the archive file to the local Maven repository.
By default, the local Maven repository is the
folder in your home directory on your local machine. Your site might prefer to
configure a central local repository.
Each EventFlow fragment project in Studio has a project structure defined by Maven standards. When you create a new project with> > > , Studio generates a project format much like following:

The folders at the top of the project are convenience links to actual file system
objects. The only folders actually created on the file system are the
target folders and the
