Hi Ignition Team, In our Ignition Project repo we also have some hidden folders that contain database scripts, pipeline scripts etc .Issue is when we zip the contents of the repo to import it to Ignition, we are getting compilation errors. So every time we need to import into Ignition we need to manually delete these hidden folders and zip the contents and import it. Is there any fix for this issue ? Let us know. Thanks. Regards, Shyam ---

First, can you explain exactly what you mean by 'hidden' folders? Hidden at the OS level? On what OS? Hidden files by the Unix convention (leading `.`) are ignored by the project system. Second, what version of Ignition is this? Third, "compilation errors" is extremely vague. Can you post the _exact_ stacktrace of any/all errors you're getting? ---

We have added a few folders named like ".database" (DOT in name to identify it as hidden folder). We use this to keep SQL scripts and other scripts. The OS is Windows 10. Version is Ignition 8.1 Error shown by designer after importing and opening the project is java.lang.IllegalArgumentException: com.inductiveautomation.ignition.common.project.resource.NameInvalidException: Name '.database' is invalid at com.inductiveautomation.ignition.designer.project.ResourceTreeNode.addChild(ResourceTreeNode.java:252) at java.base/java.util.ArrayList.forEach(Unknown Source) at com.inductiveautomation.ignition.designer.project.ResourceTreeNode.(ResourceTreeNode.java:61) at com.inductiveautomation.ignition.designer.project.DesignerProjectTreeImpl.createNode(DesignerProjectTreeImpl.java:144) at com.inductiveautomation.ignition.designer.project.DesignerProjectTreeImpl.lambda$createNode$7(DesignerProjectTreeImpl.java:141) at java.base/java.util.stream.ReferencePipeline$3$1.accept(Unknown Source) at java.base/java.util.stream.ReferencePipeline$2$1.accept(Unknown Source) at java.base/java.util.HashMap$KeySpliterator.forEachRemaining(Unknown Source) at java.base/java.util.stream.AbstractPipeline.copyInto(Unknown Source) at java.base/java.util.stream.AbstractPipeline.wrapAndCopyInto(Unknown Source) at java.base/java.util.stream.ReduceOps$ReduceOp.evaluateSequential(Unknown Source) at java.base/java.util.stream.AbstractPipeline.evaluate(Unknown Source) at java.base/java.util.stream.ReferencePipeline.collect(Unknown Source) at com.inductiveautomation.ignition.designer.project.DesignerProjectTreeImpl.createNode(DesignerProjectTreeImpl.java:142) at com.inductiveautomation.ignition.designer.project.DesignerProjectTreeImpl.lambda$new$0(DesignerProjectTreeImpl.java:74) at java.base/java.util.stream.ReferencePipeline$3$1.accept(Unknown Source) at java.base/java.util.stream.ReferencePipeline$2$1.accept(Unknown Source) at java.base/java.util.HashMap$KeySpliterator.forEachRemaining(Unknown Source) at java.base/java.util.stream.AbstractPipeline.copyInto(Unknown Source) at java.base/java.util.stream.AbstractPipeline.wrapAndCopyInto(Unknown Source) at java.base/java.util.stream.ReduceOps$ReduceOp.evaluateSequential(Unknown Source) at java.base/java.util.stream.AbstractPipeline.evaluate(Unknown Source) at java.base/java.util.stream.ReferencePipeline.collect(Unknown Source) at com.inductiveautomation.ignition.designer.project.DesignerProjectTreeImpl.(DesignerProjectTreeImpl.java:75) at com.inductiveautomation.ignition.designer.IgnitionDesigner$StartupProjectDialogHandler.lambda$new$2(IgnitionDesigner.java:2047) at java.base/java.lang.Thread.run(Unknown Source) Caused by: com.inductiveautomation.ignition.common.project.resource.NameInvalidException: Name '.database' is invalid at com.inductiveautomation.ignition.designer.project.ResourceTreeNode.addChildInternal(ResourceTreeNode.java:261) at com.inductiveautomation.ignition.designer.project.ResourceTreeNode.addChild(ResourceTreeNode.java:250) ... 25 more Ignition v8.1.22 (b2022110109) Java: Azul Systems, Inc. 11.0.16.1 ---

Try setting `-Dignition.projects.ignoredFiles=.database:.whatever:.alsowhatever` in the additional params area in `ignition.conf`. This will require a gateway restart to take effect. (one or more folder names separated by ":") ---

Thank you Kevin Added the below in the ignition.conf as mentioned, restarted the gateway and tried to import the project via the designer but still getting same error # Java Additional Parameters wrapper.java.additional.1=-Ddata.dir=data wrapper.java.additional.2=-Dignition.projects.ignoredFiles=database:azure-pipeline-scripts Any suggestions ? ---

~~It looks like the ignoredFiles setting is looking for file extensions. I don't see a dot in your configuration to signify a file extension.~~ ```auto wrapper.java.additional.1=-Ddata.dir=data wrapper.java.additional.2=-Dignition.projects.ignoredFiles=.database:.someExtension:.otherExt ``` You need to tell the it the file ~~_ **types** _ to ignore ie `.sql`~~. As per below, they are directories with the dots. ---

Not types, but explicit directories, but, the same applies - it looks like you're missing the leading `.` ---
