Lets assume that eclipse code need to be built using ant targets defined in the build.xml of main product
PRODUCT_BUILD_HOME = C:\codebase\myProduct\build
ECLIPSE_TOOL_BUILD_HOME = C:\codebase\myProduct\eclipseTool\build
Let’s assume following are the locations of the build script of the main product code and eclipse tool code :
Step-1 :Set up main build Properties (PRODUCT_BUILD_HOME) :
We need to provide the locations of eclipse code and installation so that ant target can build our eclipse tool’s code.
In the main build.properties file in PRODUCT_BUILD_HOME set the following two properties for Eclipse Tool directories
# Because of the way Eclipse PDE build operates, we need to set the absolute path
Step-2 :Set up buildEclipseCode Ant Target in the main build xml (PRODUCT_BUILD_HOME):
We need to find out the equinox jar that will build the eclipse tool’s code.
Step 3 : Set up Eclipse Tool Build Scripts (EclipseToolbuilder.bat)
We should copy the scripts (allElements.xml, customTargets.xml, build.properties) from eclipse\plugins\org.eclipse.pde.build_3.x\templates\headless-build into the ECLIPSE_TOOL_BUILD_ HOME.
The main build script from product codebase should invoke the following .bat file
java -jar -Xms512M -Xmx1024M %jarLocation% -application org.eclipse.ant.core.antRunner -buildfile %pdeLocation% -Dbuilder=%buildDirectory%/eclipse-build-script -DbaseLocation=%baseLocation% -DbuildDirectory=%buildDirectory%
java BuildCleaner %buildDirectory% %cleanCompileLog%
** Note that baseLocation and buildDirectory are the fixed names as used in eclipse build scripts.
