Description

Hi! We are using PSSA to analyze syntax errors in '.ps1' files with custom rules. It seems that a new PowerShell session is created when we invoke-ScriptAnalyzer with custom rules, then all the modules imported before are lost. So, every time we analyze a '.ps1' file with custom rules, we need to import the needed module once again. However, it is time costly for us to import modules again and again. Since we work in the continuous integration environment, we need to import the modules built by CI but not the modules installed locally. 'Import-module' ahead of the '.psm1' file of custom rules seems indispensable. Can you give some suggestions to solve the problem of import modules too many times when analyzing dozens of '.ps1' files? Thanks a lot!

Research direction

Start at the Invoke-ScriptAnalyzer entry point and trace how custom-rule .psm1 files and PowerShell sessions are handled. Reproduce analysis of several .ps1 files with CI-built modules, then determine whether the session can be reused without loading locally installed modules. Done means custom rules can use the intended imported modules without importing them for every file.
