Hi there everyone,

I would first like to congratulate and thank the Eclipse Scout team on the release of version 22.

I've tried to migrate from version 11 to version 22 but I'm having a curious problem. After updating Eclipse and following the v22 migration guide, I tried to recompile my project.

I get 16 errors (actually the same error repeated 16 times in my pom files). The error is the following:

Quote:

Description Resource Path Location Type
CoreException: Could not get the value for parameter compilerId for plugin execution default-compile: PluginResolutionException: Plugin org.apache.maven.plugins:maven-compiler-plugin:3.8.1 or one of its dependencies could not be resolved: Failed to collect dependencies at org.apache.maven.plugins:maven-compiler-plugin:jar:3.8.1 -> org.eclipse.tycho:tycho-compiler-jdt:jar:2.4.0: ArtifactDescriptorException: Failed to read artifact descriptor for org.eclipse.tycho:tycho-compiler-jdt:jar:2.4.0: ArtifactResolutionException: org.eclipse.tycho:tycho-compiler-jdt:pom:2.4.0 failed to transfer from https://repo.eclipse.org/content/groups/releases/ during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of eclipse.release has elapsed or updates are forced. Original error: Could not transfer artifact org.eclipse.tycho:tycho-compiler-jdt:pom:2.4.0 from/to eclipse.release (https://repo.eclipse.org/content/groups/releases/): The operation was cancelled. pom.xml /myapp.server.app.war line 6 Maven Project Build Lifecycle Mapping Problem


The error appears on the same first line; <parent> in the pom files.
  <parent>
    <groupId>org.eclipse.scout.apps</groupId>
    <artifactId>myapp</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <relativePath>../myapp</relativePath>
  </parent>


I am working in Linux and I have Apache Maven 3.6.3 installed from the Linux Mint repository (sudo apt install maven).

Thanks a lot for your assistance.

JD

Hi there everyone,

I finally got round the problem by updating the project using "Force Update....". However now when I try to run the app, the Webapp launch remains stuck at 63%

Any ideas what could be the problem?

Thanks a million,

JD

Hi JD,

this happens because the webpack build output has changed. You need to adjust your launch group. I've just added a section to the migration guide: https://eclipsescout.github.io/22.0/migration-guide.html#eclipse-launch-group
