Multiple errors in eclipse regarding new node project (including bundled example node)

Node Development
1

Hello,
I completed setting up my eclipse environment Version: 2018-12 (4.10.0), then I followed the instructions for installing the KNIME SDK https://github.com/KNIME/knime-sdk-setup/ I selected master branch.

Then I installed the New Node Wizard for eclipse and proceeded to the instructions for creating a new node https://www.knime.com/developer/documentation/wizard

However both the example node project and the new node that I created have the same errors. When I try to launch Knime from debug mode in eclipse it gives the following

Untitled

It looks like your Target Platform may not of either fully resolved or been applied. To check, try opening the relevant *.target file from the org.knime.sdk.setup project, and try the reload button. Once that has completed (it may take quite some time the first time round), then you should be able to click on ‘Set as Target Platform’ at the top of the Target Definition editor window:

You should probably also check that under the project menu in eclipse, ‘Build Automatically’ is checked:

And also, if you still have errors, try the Clean... option from the same menu, selecting the Clean all projects option.

Hope that helps,

Steve
