1 Introduction
Following the previous ArcGis series-java calling GP analysis , the release, call, and polling of gp tools have been realized, and the vector data json, raster data tif files and style files required for publishing map services have been saved separately
To publish the results of gp analysis as a layer for front-end display, the basic python environment is still the same as publishing the space table , and
the implementation idea is basically the same. It is also to use the local empty project structure to add layers to build draft files to upload and publish
2, java code
If the execution of calling the published python is successful, first check the publishing address in the content of the ArcGIS Enterprise console, and
then splicing the correct publishing address in the getPublishLayerUrl method

3. Python code
Traverse the json file and tif file in the project, add them all to the new project, and then create a draft;
because the gp analysis id is used as the serverName, the front end allows repeated analysis, so you must set coverage when publishing

4, problems that may be encountered
If the version of arcgis pro is not compatible with the service version of arcgis, the python under pro will also report some strange errors. I use 3.0.1 pro and 10.6 arcgis; if you execute the python script package url problem, you can switch between https
and Try http, it is related to the version of arcgis;
when debugging, you can view the execution log in the manage of arcgis https://aaa.myarcgis.com:6443/arcgis/manager
