I know that page exists, the point of "multiple issues" is that it does not work. The generated output is close to empty, for example: ``` --- title: Pipeline add-constants --- * Filename : add-constants.hpl * Last modified: 2023-02-05 11:09:40 ## Image  ``` I initially tested this on Windows, but same/similar issues on Linux and MacOS. This is a copy/paste from the command on the documentation page, only changed "demo" to "samples". The `Error calling extension point(s) for the pipeline painter transform` error obviously is repeated for every hpl/hwf file. `./hop doc -j samples -t /tmp/hop/docs --include-notes --include-parameters --include-metadata` ``` ./hop doc -j samples -t /tmp/hop/docs --include-notes --include-parameters --include-metadata 2025/12/10 19:57:03 - HopDoc - Enabling project 'samples' 2025/12/10 19:57:03 - HopDoc - Documenting folder: /Users/bart/git-hop/hop/assemblies/client/target/hop/config/projects/samples for project samples 2025/12/10 19:57:03 - HopDoc - Processing documentation folder . 2025/12/10 19:57:03 - HopDoc - Processing pipelines and workflows in folder . 2025/12/10 19:57:03 - HopDoc - Processing documentation folder neo4j 2025/12/10 19:57:03 - HopDoc - Processing pipelines and workflows in folder neo4j 2025/12/10 19:57:03 - HopDoc - - documenting pipeline: neo4j-cypher-complex-returns.hpl to /tmp/hop/docs/neo4j/neo4j-cypher-complex-returns-pipeline.md 2025/12/10 19:57:04 - General - ERROR: Error calling extension point(s) for the pipeline painter transform 2025/12/10 19:57:04 - General - ERROR: java.lang.NullPointerException: Cannot invoke "org.apache.hop.ui.hopgui.perspective.HopPerspectiveManager.findPerspective(java.lang.Class)" because the return value of "org.apache.hop.ui.hopgui.HopGui.getPerspectiveManager()" is null 2025/12/10 19:57:04 - General - at org.apache.hop.ui.hopgui.HopGui.getExplorerPerspective(HopGui.java:1663) 2025/12/10 19:57:04 - General - at org.apache.hop.testing.gui.TestingGuiPlugin.getStateMap(TestingGuiPlugin.java:1180) 2025/12/10 19:57:04 - General - at org.apache.hop.testing.gui.TestingGuiPlugin.getCurrentUnitTest(TestingGuiPlugin.java:1195) 2025/12/10 19:57:04 - General - at org.apache.hop.testing.xp.DrawGoldenDataSetOnTransformExtensionPoint.callExtensionPoint(DrawGoldenDataSetOnTransformExtensionPoint.java:54) 2025/12/10 19:57:04 - General - at org.apache.hop.testing.xp.DrawGoldenDataSetOnTransformExtensionPoint.callExtensionPoint(DrawGoldenDataSetOnTransformExtensionPoint.java:41) 2025/12/10 19:57:04 - General - at org.apache.hop.core.extension.ExtensionPointMap.callExtensionPoint(ExtensionPointMap.java:149) 2025/12/10 19:57:04 - General - at org.apache.hop.core.extension.ExtensionPointHandler.callExtensionPoint(ExtensionPointHandler.java:41) 2025/12/10 19:57:04 - General - at org.apache.hop.pipeline.PipelinePainter.drawTransform(PipelinePainter.java:925) 2025/12/10 19:57:04 - General - at org.apache.hop.pipeline.PipelinePainter.drawPipeline(PipelinePainter.java:295) 2025/12/10 19:57:04 - General - at org.apache.hop.pipeline.PipelinePainter.drawPipelineImage(PipelinePainter.java:204) 2025/12/10 19:57:04 - General - at org.apache.hop.pipeline.PipelineSvgPainter.generatePipelineSvg(PipelineSvgPainter.java:82) 2025/12/10 19:57:04 - General - at org.apache.hop.documentation.PipelineDocDelegate.buildPipelineDocumentation(PipelineDocDelegate.java:81) 2025/12/10 19:57:04 - General - at org.apache.hop.documentation.DocBuilder.processHopFolder(DocBuilder.java:401) 2025/12/10 19:57:04 - General - at org.apache.hop.documentation.DocBuilder.processDocumentationFolder(DocBuilder.java:333) 2025/12/10 19:57:04 - General - at org.apache.hop.documentation.DocBuilder.buildDocumentation(DocBuilder.java:210) 2025/12/10 19:57:04 - General - at org.apache.hop.documentation.DocBuilder.run(DocBuilder.java:185) 2025/12/10 19:57:04 - General - at picocli.CommandLine.executeUserObject(CommandLine.java:2045) 2025/12/10 19:57:04 - General - at picocli.CommandLine.access$1500(CommandLine.java:148) 2025/12/10 19:57:04 - General - at picocli.CommandLine$RunLast.executeUserObjectOfLastSubcommandWithSameParent(CommandLine.java:2469) 2025/12/10 19:57:04 - General - at picocli.CommandLine$RunLast.handle(CommandLine.java:2461) 2025/12/10 19:57:04 - General - at picocli.CommandLine$RunLast.handle(CommandLine.java:2423) 2025/12/10 19:57:04 - General - at picocli.CommandLine$AbstractParseResultHandler.execute(CommandLine.java:2277) 2025/12/10 19:57:04 - General - at picocli.CommandLine$RunLast.execute(CommandLine.java:2425) 2025/12/10 19:57:04 - General - at picocli.CommandLine.execute(CommandLine.java:2174) 2025/12/10 19:57:04 - General - at org.apache.hop.hop.Hop.main(Hop.java:129) 2025/12/10 19:57:04 - General - ERROR: Error calling extension point(s) for the pipeline painter transform ``` -- This is an automated message from the Apache Git Service.
