Method Details

setPythonExecutable

public static void setPythonExecutable(File exec)

Defines the (global) Python executable.

Parameters:

exec - the executable, may be null for dynamically determined

getPythonExecutable

public static File getPythonExecutable()

Returns the Python executable. We consider the following precedences:

1. Local python3 in Linux Jenkins installation (for testing, although this is production code; with installation path)
2. Local python3 in default Linux installation ("/usr/bin", with installation path)
3. The global python executable setPythonExecutable(File) (with installation path)
4. The command "python"

Returns:

the executable, returns at least "python"; the result may be an absolute path but must not be. Calling File.getAbsolutePath() on the result may be misleading - if required, use it as string.

getPythonExecutable

public static File getPythonExecutable(String pythonBinary)

Returns the Python executable. We consider the following precedences:

1. Local python3 in Linux Jenkins installation (for testing, although this is production code; with installation path)
2. Local python3 in default Linux installation ("/usr/bin", with installation path)
3. The global python executable setPythonExecutable(File) (with installation path)
4. The command "python"

Parameters:

pythonBinary - explicitly given path to python binary

Returns:

the executable, returns at least "python"; the result may be an absolute path but must not be. Calling File.getAbsolutePath() on the result may be misleading - if required, use it as string.
