talend-codegen

Updated : Nikita Rousseau 02/08/2017 for Talend Open Studio - Big Data 6.4.1

Command line code generation (job build/export) plugin for Talend, updated for >= v6.4.1

Compiling & Configuring

Build:

#ls in the out directory
>ls jar/talend-codegen_X.X.X.jar

#build directly with ant:
>ant build -Dtalend_version=6.4.1 -Dtalend_revision=20170623_1246

And copy jar/talend-codegen<version>.jar to the plugins directory of Talend.

Usage invoking TOS directly

Invoke talend with the following mandatory command line arguments:

  • -projectDir - the project directory where the project can be found
  • -jobName - name of the job to be exported
  • -targetDir - the directory where the exported job will be placed

Eclipse application arguments

  • -application au.org.emii.talend.codegen.Generator - run the code generation plugin
  • -nosplash stops the display of the gui splash window
  • --launcher.suppressErrors stops errors being displayed in message boxes - output to stderr instead
  • -data specifies the talend workspace used for building the project - created automatically if it doesn't exist (recommended to ensure a clean build)
  • --clean_component_cache tells TOS to reload external components and rebuild the cache

Some optional command line arguments you can have:

  • -version - version of job to be exported
  • -componentDir - location of any custom components used in the job
  • -needLauncher - include launcher script (true/false)
  • -needSystemRoutine - include system outines (true/false)
  • -needUserRoutine - and so on..
  • -needTalendLibraries
  • -needJobItem
  • -needSourceCode
  • -needDependencies
  • -needJobScript
  • -needContext
  • -applyToChildren

Example:

export JOBNAME=MyJob
export WORKSPACE=/home/projectname/workspace
export PROJECTDIR=/home/projectname/workspace/MYPROJECT
export TARGETDIR=/home/projectname/workspace/.talend-build
export COMPONENTDIR=/home/projectname/custom_components
