Python virtual environments

Most simple usage

virtualenv {
    sh(script:'python -m install spline')
    sh(script:'python -m spline.application --help')
}

Passing requirements

virtualenv(['spline', 'requests==2.12.4']) {
    sh(script:'python -m spline.application --help')
}

Defining another virtual environment folder

virtualenv(['spline', 'requests==2.12.4'], 'another-venv') {
    sh(script:'python -m spline.application --help')
}

Error handling

When inside a virtual environment an exception is thrown:

• the result of such a block is null.
• the pipeline state (currentBuild.result) will be set to 'FAILURE'.
• the virtual environment will be removed independent of that issue.
