talend-codegen

Command line code generation (job export) plugin for Talend open studio 7.3.1

Building/Installation

• mvn clean package
• Copy generated .jar in target directory to plugins directory of Talend
• Open the file config.info in the folder configuration/ of your Talend Studio 7.3.1
• At the end of the very long line for osgi.bundles= add ,au.org.emii.talend.codegen (so something like osgi.bundles=blalbblabla,au.org.emii.talend.codegen )

Usage

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

This example is taken from our Jenkins build process - $WORKSPACE is the location of the talend project

TOS_DI-linux-gtk-x86_64 -nosplash --launcher.suppressErrors -data $WORKSPACE/../.talend-workspace --clean_component_cache -application au.org.emii.talend.codegen.Generator -jobName ThreddsExample -projectDir $WORKSPACE -targetDir $WORKSPACE/.talend-build -componentDir /par2/git-repos/talend_components
