Script
Getting started
To generate a basic PowSyBl distribution, you can then launch from the root repository:
$ cd <PROJECT_ROOT_PATH>
$ mvn clean package
The PowSyBl distribution is generated in the <PROJECT_ROOT_PATH>/target folder. For easier use of itools commands, adding
<PROJECT_ROOT_PATH>/target/powsybl-distribution-<powsybldistribution.version>/bin to your environment variable PATH is recommended.
Notes:
- Test network files in the
resourcesfolder are present in theetcfolder of the generated distribution. - A configuration file is provided in this distribution but will be overriden by your local configuration file if you have one.
