QGIS installation finder¶
Use this job to find installed QGIS version for automatic definition of QDT environnement variable QDT_QGIS_EXE_PATH
(used for shortcut creation).
If the environment variable is already defined and a valid QGIS installation is found by this variable, the job is skipped.
Compatibility¶
This job is compatible with:
Windows
Linux
Use it¶
Sample job configuration in your scenario file:
- name: Find installed QGIS
uses: qgis-installation-finder
with:
version_priority:
- "3.36"
if_not_found: error
Options¶
version_priority¶
Since multiple versions of QGIS can be easily installed on Windows, this option is used to specify the preferred QGIS version.
For example if you define:
- name: Find installed QGIS
uses: qgis-installation-finder
with:
version_priority:
- "3.34"
- "3.36"
QDT will first use 3.34.z versions. If none are available it will use 3.36.z versions.
If multiple 3.34.z versions are available, the latest will be used. For example if 3.34.1 and 3.34.5 version are available, 3.34.5 will be used.
If any version of version_priority
is available, then the most recent version found is used.
The environment variable QDT_PREFERRED_QGIS_VERSION
is used as top priority if defined.
if_not_found¶
This option determines the action to be taken if QGIS is not found during the search process.
Possible_values:
warning
(default): if no version found, a warning is displayed in QDT logserror
: if no version found, QDT stops and the other jobs are not run
How does it work¶
On Linux, QDT locates installed QGIS with which
command.
On Windows QDT tries to locate installed versions in the following directories:
%PROGRAMFILES%\\QGIS x.y.z\\bin\
%QDT_OSGEO4W_INSTALL_DIR%
(default value :C:\\OSGeo4W
)
By default, the most recent version found is used.
