Importing KNIME Core Components into Eclipse After Successful SDK Setup

[kornblume]

Hi KNIME Team,

I attempting to build the KNIME Analytics Platform (version 5.4.4) from source code. Following the instructions in the knime-sdk-setup repository, I successfully configured the KNIME-AP.target file and validated that the target platform resolves correctly in Eclipse. However, when importing critical components (e.g., knime-core-ui, knime-workbench), Eclipse consistently throws errors, preventing further progress. Despite reviewing community discussions (thread 1, thread 2), I remain unable to resolve these issues independently.

Below, I detail my environment, steps taken, and specific problems for your reference:

Environment & Setup

• KNIME Version: 5.5.0 (branch analytics-platform/5.5.0).
• Eclipse IDE: Eclipse IDE for RCP Developers (2024-03 release).
• Java: JDK 17 (aligned with Eclipse requirements).
• Target Platform: KNIME-AP.target loaded without errors.

Steps Taken

1. SDK Setup:
   • Cloned knime-sdk-setup, executed mvn clean install for the target platform.
   • Verified KNIME-AP.target resolves all dependencies (no missing plugins in Eclipse).
2. Project Import:
   • • Downloaded source code ZIP files for knime-core, knime-core-ui, and knime-workbench from GitHub and imported them via “Existing Projects into Workspace”.
3. Error Manifestation:
   • Dependency Issues: Eclipse reports compilation errors due to unresolved classes (e.g., org.eclipse.ui classes in knime-core-ui).
   • JDK Compatibility: Adjusted project-specific JRE settings to JDK 17 (verified via Java Build Path).

Specific Queries

1. Dependency Resolution:

   • Are additional repositories (beyond knime-sdk-setup) required for knime-core-ui? The target platform resolves dependencies, but Eclipse still flags org.eclipse.ui imports as errors.

2. Project Import Method:

• Could the errors be caused by incorrect import procedures? I downloaded the source ZIPs for knime-core-ui, knime-workbench, etc. from GitHub and imported them as “Existing Projects into Workspace”. Is this the recommended approach, or should these components be imported differently?

Best regards,
Korn
