Build failure 'Cannot invoke org.eclipse.pde.internal.core.schema.SchemaProvider.createSchema" on fresh SDK installation #167

Closed kthoms closed 8 months ago

kthoms commented 8 months ago

I have just set up a fresh SDK development environment using the Oomph Auto-Install according to the Contribution guideline.

This worked mostly well, but at the very end a Build Problem dialog appears. Bildschirm­foto 2023-11-01 um 09 40 54

Details show that for multiple project the same error appears:

Errors running builder 'Extension Point Schema Builder' on project 'org.eclipse.core.expressions'.
Cannot invoke "org.eclipse.pde.internal.core.schema.SchemaProvider.createSchema(org.eclipse.pde.internal.core.ischema.ISchemaDescriptor, String)" because "this.schemaProvider" is null

The error does not look as it harms the setup, however, it should not appear.

@kthoms any chance there is an entry in the Error Log with a full stacktrace?
