PNPM - The "from" argument must be of type string [message #1831757]

Good day,

I have performed the upgrade steps using the migration tool and documentation for a project that was originally written using Eclipse Scout 9.

I have made the ui.html to use pnpm because when I perform a Maven build the PNPM step complains that another package manager installed dependencies and it cannot move them.

The issue is that when I do successive builds I receive the error below. What I need to do then is delete the dependencies in the node_modules (which takes some time) and then reattempt the build.

I am using maven_rt_plugin_config-master version 3.10.0 because the prior version gave various other issues and it seems that version 3.11.x is meant for the upcoming Eclipse Scout 11.

I have tried running the build command in elevated mode on Windows 10 but that does not resolve the issue either and I am using Maven 3.6.3 with OpenJDK 11.0.7

Hi Mark

I can't comment on that particular error as I haven't encountered it myself yet. But regarding the maven_rt_plugin_config-master: You can use the current release 3.12.7 with Scout 10. And if possible I would use the latest Scout RT version 10.0.30.

Hi Arthur,

I made the changes as suggested but then I got the following Antrun error:-

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.8:run (check-npm-install-workspace) on project management.ui.html: An Ant BuildException has occured: Could not create C:\SDE\Code\Scout\...\management\management\pom.xml\target\npm_update.marker
[ERROR] around Ant part ...<touch file="C:\SDE\Code\Scout\...\management\management.ui.html\../management/pom.xml\target\npm_update.marker" mkdirs="true"/>... @ 6:142 in C:\SDE\Code\Scout\...\management\management.ui.html\target\antrun\build-main.xml: The system cannot find the path specified

I had a look at the contacts project in the Github repository for Eclipse Scout documentation and I noticed that the Maven projects do not specify the pom.xml when referring to the parent project.

I updated the projects and it seems to be working now.

Thank you very much for your assistance :-)
