Legacy Eclipse

Using Eclipse with Ant Cayenne

(versions 1.2 and 2.0)

Configuring Eclipse Workspace for Cayenne

  • Download and install Eclipse . Eclipse 3.1.1 or newer is recommended, as there are some per-project settings in repository that are not understood by older Eclipse.
  • Install both JDK1.4 and 1.5. Some Cayenne projects below require JVM 1.5.x, and others - JVM 1.4.x. It is possible to develop all or parts of Cayenne with just 1.5 or just 1.4, but make sure you understand what you are doing.
  • Set JVM 1.4 as default workspace JVM.
  • Define "JRE_LIB_15" Eclipse variable (Preferences -> Java -> Build Path -> Classpath Variable) to point to the JRE 1.5 class library (e.g. "JRE15_HOME/jre/lib/rt.jar" on Windows and Linux or "/System/Library/Frameworks/JavaVM.framework/Versions/1.5/Classes/classes.jar" on Mac OS X). Cayenne projects that are compatible with 1.5 rely on this variable.

Checking Out Eclipse Projects

Under cayenne folder in Subversion you'll find 4 Eclipse projects that need to be checked out to the same workspace. You may skip projects marked as optional if you are not planning to use/change them.

Project Folder JVM Special Setup Notes
/cayenne-java 1.4.x n/a Eclipse project containing main Cayenne source and library folders. Source and binary compatibility must be set to JDK 1.4.
/cayenne-java-1.5 1.5.x JRE_LIB_15 variable Eclipse projectcontaining Cayenne JDK 1.5 specific code. Requires "cayenne-java" project to be present in workspace. Source and binary compatibility must be set to JDK 1.5.
/cayenne-other 1.5.x JRE_LIB_15 variable Optional Eclipse project that contains Cayenne documentation, contrib folders and such.
/cayenne-ant n/a n/a Eclipse project with Ant build files to build the entire Cayenne workspace. Needed if you are planning to build Cayenne with Ant outside of Eclipse (i.e. to create JAR files or run a test suite).

There are also various tutorials in "cayenne" folder that are not needed to build the framework or the tools.
