     Gets the list of custom code analyzers to use for compilation.
 .DESCRIPTION
     Returns an array of custom code analyzer paths based on the settings provided.
-    If the custom code cop is a URL, it will be downloaded to the compiler folder and the local path will be returned.
+    URL-based entries are downloaded to the compiler folder. Relative file paths
+    are resolved against the project folder so that workspace compilation passes
+    rooted paths to altool/alc.exe (altool only resolves the first comma-separated
+    --customanalyzers entry against the project root, so relative paths beyond the
+    first one fail to load).
 .PARAMETER Settings
     Hashtable containing the build settings with custom code cop paths or URLs.
 .PARAMETER CompilerFolder
-    The folder where the AL compiler tool is located, used for downloading custom analyzers if URLs are provided.
+    The folder where the AL compiler tool is located, used for downloading custom
+    analyzers if URLs are provided.
+.PARAMETER ProjectFolder
+    Folder used as the base for resolving relative customCodeCops entries.
+    Defaults to the current location, which Compile.ps1 sets to the project folder.
 .OUTPUTS
-    Array of custom analyzer paths to use for compilation.
+    Array of absolute custom analyzer paths to use for compilation.
