  1. Control System Studio Training-Development Setup Kay Kasemir ORNL/SNS kasemirk@ornl.gov April 2013

  2. Getting CSS to run from source code • Get Java, Eclipse, CSS Sources • Start Eclipse • “Import”Sources into Workspace • Open CSS *.product file, Launch

  3. Java • Check: Is java available? java -version Need Sun/Oracle Java 1.7;Not GCJ, OpenJDK

  4. Eclipse Versions • Eclipse just went from 3.x to 4.x • Can use Eclipse 4.x as IDE • CSS Production code: Currently Eclipse 3.7.2 • Can use 4.x IDE with 3.7.2 “Target Platform” • Ongoing port to 4.x

  5. Start Eclipse • Run eclipse/eclipse “Workspace”:use CSS/Workspace in your home directory • Suggest to check Preferences: • Java, Installed JREs: Is it the one you want? • Eclipse may automatically find a JRE, but you want the JDK for source-level debugging • Usage Data Collector: Disable capture? • Add (older) version of Eclipse as “Target Platform”?

  6. Source Code vs. Eclipse Workspace • Source Code: • Where the sources are • Workspace:Directory with“.metadata”subdir. • Tracks currentlyopen window, … To avoid confusion: Keep Separate! • Example: Use CSS/Sources, CSS/Workspace

  7. Eclipse Workspace “Import” Sourcesinto Workspace: • File/Import…,General,Existing Projectsinto Workspace • Select “root” directory,import all projects found • Do not“Copy projects into Workspace” Note: Need to “Import” even if sources are already located in workspace directory

  8. Run Product Open org.csstudio.basic.epics.product/*.product Press • Synchronize • Launch an Eclipse application • Later, re-run via the Run button in toolbar

  9. Fundamentally, that’s it • Product: • List of plugins • *.product file to run the product • IDE can also ‘export’ product binary • Feature: • Logical group of plugins • Allows online ‘install’, automated ‘update’

  10. “Headless Build” • Command-line process to turn *.product or *.feature into binary • Can be scripted, launched from Hudson, … • Sadly, somewhat in parallel to IDE: • Specific directory layout • Need to copy sources into plugins/ and features/ folders • Additional build.properties file • Target platform, Java object code level, ..

  11. “Update Site” • Fundamentally, just a build option to create “P2 Metadata Repository” for products and features • Published on web site • Products can then • Install features from repository • Automatically update to latest version • Requires careful setting of dependencies and version numbers
