In all cases, Isomorphic strongly recommends using some form of dependency management in
your project, as it dramatically simplifies framework installation and upgrades. Most teams
with Java experience are at least familiar with Maven so Smart GWT also
includes support for publishing both client and
server components to a Maven repository. Note that your project doesn't necessarily need to be
built with Maven, it just needs to be able to retrieve its dependencies from that repository.
Gradle and Ivy are two popular
alternatives, for example.
Those who still wish to manage the installation manually should
refer to the separate documentation topic covering the manual installation. The rest of this overview
touches briefly on context, tips, and tricks for those who want to follow best practices but
may not necessarily have experience with Maven.
"Maven is a software project management and comprehension tool", whose key features include a mechanism for dependency resolution as recommended above. In short, Maven attempts to retrieve these resources first from a local repository. If the resource isn't found, it attempts to retrieve it from one or more remote repositories, and caches it for subsequent attempts.
Most open source Java libraries can be found on the (remote) Maven Central repository, which requires no configuration to use. Occasionally, however, the library you need isn't published to any public repository, and you'll need to install it locally or deploy it to a remote repository. Most environments should be using a remote repository provided by a repository manager set up and maintained by your organization.
Smart GWT is not published to any public repository, and so will need to be
installed or deployed before you're able to use it in any project. This can be quite tedious
when it has to be done for as many artifacts as are provided in current distributions, so an open source Maven
"Plugin" is made available with install and deploy goals that each are capable of downloading, unpacking, and
installing or deploying Patch & Development Builds in a single step. After Maven has been downloaded, installed, and configured (some configuration required for other than LGPL or EVAL Smart
GWT builds), this whole process takes no more than a few minutes on a reasonably fast network.
Refer to MavenSupport documentation for a command that you can
copy and paste to install the most recent evaluation version of Smart GWT, and another to get
you started by generating a skeleton project from a Maven archetype, or
template.
Having run both of those commands, your newly created project will contain a pom.xml file, which details among other things the libraries, or
dependencies, needed to compile, package, and run the app. In this case, you'll find a
reference to the version of Smart GWT you used to create the project. To upgrade, you'll just
change the value of the ${smartgwt.version} property to reflect another build number that
you've installed or deployed using the process outlined above and rebuild. To add another JAR
to your project, you just add the dependency to your POM. To add one of the Smart GWT optional modules, for example, you'd first use
the plugin to install / deploy it to your own repository and then add the appropriate block to
your POM's dependencies section.
Your project will also contain a README file containing a copy/paste command line for installing, deploying to and starting a local 'embedded' Jetty server, as well as detailed instructions for Eclipse integration, and even automated conversion to an Ant based build (complete with Ivy configuration). Isomorphic generally recommends starting with the Jetty command to see things working quickly before experimentation with other approaches. The plugin provides an FAQ for reference, and posting questions / issues to the public forum for help is always appropriate.
