How do you though use the various existing samples and examples that are provided with Tuscany from within Eclipse? Here we'll provide some instructions about how to do just that for both the Maven user and the non-Maven user. As an example we'll look specifically at how to import the introducing-trips contributions and the jumpstart launcher that runs it from the <A href="sca-java-travel-sample-1x-releases.html" title="SCA Java Travel Sample 1.x Releases">Tuscany SCA Travel Sample</A>. We'll also explain how to use the same approach to import other samples such as the samples in the Tuscany SCA Java binary distribution and the complete travel sample code.</P> + +<P>These instructions assume that the sample code being loaded into Eclipse has been downloaded and unzipped and the sample modules have already been compiled using Maven or Ant following the instructions in the sample's README. This is important because some of the source in sample modules is generated during the compile stage and you'll need to import that into Eclipse along with the other source code and resources that the sample modules contain. These instructions were written using Eclipse 3.5.2.</P> + +<P>Both of the approaches described below import the sample modules into Eclipse without copying them. This means that any edits to the sample resources that you make in Eclipse will result in changes in the directories where you unzipped the sample, and you won't see copies of these projects appear in the Eclipse workspace directory on disc. This is generally a useful approach as it lets you work directly on projects outside of the Eclipse workspace. In the case of the travel sample it's particularly important because there are some cross references between the various modules in the sample. If you copy the projects out of the sample structure they won't run properly without further editing.</P> + + +<H1><A name="ImportexistingTuscanySCAprojectsintoEclipse-1FortheMavenuser"></A>1 - For the Maven user</H1> + +<H2><A name="ImportexistingTuscanySCAprojectsintoEclipse-1.1CreatingEclipseprojectfiles"></A>1.1 - Creating Eclipse project files</H2> + +<P>Maven has a <A href="http://maven.apache.org/guides/mini/guide-ide-eclipse.html" class="external-link" rel="nofollow">plugin</A> which will convert a Maven project into an Eclipse project. For example, to load the travel sample's introducing-trips contribution into Eclipse as a project first do the following:</P> + +<DIV class="code panel" style="border-width: 1px;"><DIV class="codeContent panelContent"> +<PRE class="code-java"> +cd travelsample/contributions/introducing-trips +mvn eclipse:eclipse +</PRE> +</DIV></DIV> + +<P>That generates, amongst other things, .classpath and .project files into the introducing-trips directory. These files effectively make the introducing-trips module an Eclipse project that can be loaded directly into Eclipse. This Eclipse project will reference dependencies in the local Maven repository, based on the contents of the pom.xml file. These dependency references are constructed using an Eclipse classpath variable called M2_REPO.</P> + +<P>The previous example shows how to run a <TT>mvn</TT> command to create a single Eclipse project. It's often useful to run a single <TT>mvn</TT> command from a top-level directory to create multiple Eclipse projects. For example, to create Eclipse projects for all the samples in the Tuscany SCA Java 1.6.1 (or later 1.x) binary distribution, you can do the following:</P> + +<DIV class="code panel" style="border-width: 1px;"><DIV class="codeContent panelContent"> +<PRE class="code-java"> +cd samples +mvn eclipse:eclipse +</PRE> +</DIV></DIV> + +<P>This runs the <TT>mvn eclipse:eclipse</TT> command for all the samples under the top-level <TT>samples</TT> directory. As well as being more convenient than running a <TT>mvn eclipse:eclipse</TT> command for each sample, using a single <TT>mvn eclipse:eclipse</TT> command from a top-level directory enables the Maven plugin to discover any dependency relationships between the samples and create corresponding dependency relationships between the generated Eclipse projects. You can do this for the complete travel sample by doing the following:</P> + +<DIV class="code panel" style="border-width: 1px;"><DIV class="codeContent panelContent"> +<PRE class="code-java"> +cd travelsample +mvn eclipse:eclipse +</PRE> +</DIV></DIV> + +<H2><A name="ImportexistingTuscanySCAprojectsintoEclipse-1.2SettingtheM2REPOvariable"></A>1.2 - Setting the M2_REPO variable</H2> + +<P>Before loading the project into Eclipse you need to set M2_REPO as a classpath variable in your workspace to tell it where the Maven repository is.</P> + +<P>You can do this with Maven using the following command.</P> + +<P><TT>mvn -Declipse.workspace=<path-to-eclipse-workspace> eclipse:add-maven-repo</TT></P> + +<P>Alternatively you can do it manually by opening the Eclipse workspace you’re going to use and then:</P> + +<P>Select Window/Preferences<BR class="atl-forced-newline"> +From the resulting “Preferences” dialog select Java/Build Path/Classpath Variables<BR class="atl-forced-newline"> +Select the “New…” button<BR class="atl-forced-newline"> +In the “Name:” field type M2_REPO<BR class="atl-forced-newline"> +In the “Path:” field type <path to your maven repo></P> + +<H2><A name="ImportexistingTuscanySCAprojectsintoEclipse-1.3LoadinganexistingprojectintoEclipse"></A>1.3 - Loading an existing project into Eclipse</H2> + +<P>Once M2_REPO is set you can load the project(s) into Eclipse by opening the Eclipse workspace you’re going to use and then:</P> + +<P>Select menu File/Import…<BR class="atl-forced-newline"> +From the resulting “Select” dialog box select General/Existing Projects into Workspace<BR class="atl-forced-newline"> +From the resulting “Import Projects” dialog box select the “Browse…” button to locate the directory containing the project(s) to import<BR class="atl-forced-newline"> +Select “Finish”</P> + +<P>For example, to load the contributions/introducing-trips project from the travel sample, you would select the <TT>travelsample/contributions/introducing-trips</TT> directory.

Most of the effort is involved in working out what the dependencies are.</P> + +<P>To import projects without using Maven you first need to make all of the Tuscany libraries available to the SCA projects you'll be loading into Eclipse. You can do this by creating a TUSCANY library variable.
