New Eclipse Version

Introduction

It has been a while since I installed Eclipse, but when I had searched at that time, I had not found a detailed blog describing the installation of Eclipse for ABAP Development Tool(ADT). I was successful in installing the Eclipse for ADT, even though I did not know the ABCs of system ‘path variables’ or JavaRuntime(JRE). So, I am writing this blog for all the people who are in the same boat.

Before diving deep into the technical details, let me throw some light as to why we need to do this. ABAP Development Tool(ADT) is an Eclipse based tool provided by SAP. You will need ADT if you have to work on the HANA CDS Views. Even though, CDS views are embedded into the ABAP Dictionary, there are some differences in the features available between the Eclipse and the Data Dictionary environments. You will get a better idea if you go through this blog. I am elaborating all the steps I followed and the troubleshooting I did for a successful installation of Eclipse for ADT.

If you clone a new repository via the Eclipse IDE, it will be cloned by default to a new sub-folder in a default directory. This default path can be configured via the Windows Preferences Team Git entry in the Default Repository folder field.

Steps for the Installation

  1. The new Eclipse capabilities will be on display from July 24 -27, 2005, at the American Association of Physicists in Medicine (AAPM) meeting in Seattle, Washington. About Varian Medical Systems Varian Medical Systems, Inc., of Palo Alto, California is the world's leading manufacturer of integrated cancer therapy systems, which are treating.
  2. You may need to know the version of Eclipse for several reasons. For example, if you want to install Maven or Spring plugins, you may need which version of t.

  4. Eclipse: Second Dawn for the Galaxy is a revised and upgraded version of the Eclipse base game that debuted in 2011 that features: New graphic design, while maintaining the acclaimed symbology of the first edition; A full line of Ship Pack 1 miniatures; New miniatures for ancients, GCDS, orbitals, and more; Custom plastic inlays; Custom combat dice.

The following is the Step-by-step installation of Eclipse for ABAP development Tool on Eclipse.

  1. Install JAVA
  1. Next, Install Eclipse for JAVA developers

Pay attention to what your system configuration is? 32 bit or 64 bit. Install accordingly.

  1. Extract eclipse and cut the Eclipse folder

I created folders SAPADT in the ‘Program files’ in ‘C:’ drive. So, the path looks like:

‘C:Program FilesSAPADT’ and pasted the Eclipse folder here.

And created a desktop shortcut.

  1. When I tried to run the Eclipse (short on my desktop), I got this error:

Eclipse Error

  1. To solve this, install JRE from this link: https://www.oracle.com/java/technologies/javase-jre8-downloads.html
  2. To maintain path variable for this JRE:
  • Go to ‘This PC’ and right click and click on ‘Properties’

Eclipse git pull request. PC Properties

  • Go to Advanced system settings

Advanced Settings

  • Click on ‘Environment Variables’

Environment Variables

  • And click on NEW

You should give the path where the JRE is in your system.

  • The path is my system looks like

C:Program Files (x86)Javajre1.8.0_251bin
to give you some idea.

  • This solved the ‘JAVA was started but returned exit code = 1’ error
    8. Now, start the eclipse application and select a directory for workspace. You may select the checkbox if you don’t want to be asked again.

Launch Eclipse and select Workspace

  1. Now go to Help…Install New Software

Work with https://tools.hana.ondemand.com/latest

And click on Finish.

  1. Then open perspective ‘ABAP’. Click on ABAP and click on OPEN.

Then I encountered this error after I tried logging into the SAP ABAP system:

Microsoft Visual C++ Error

  1. I found out that I had to install MS Visual C++ from this link:

Download MS Visual C++ DLL from this link

And then I was able to finally open the SAP system from Eclipse.

I hope this blog made it easier for you to troubleshoot all the issues while installing Eclipse for ADT. Please leave any comments or suggestions you might have.

Periodically, Eclipse gets updated and Triquetrum should be updated to the most recent version of Eclipse.

Below are the changes necessary.

See Milestone and Release Builds

Update the tpd files

  1. We use Target Platform Definition (.tpd) files to define .target files, so edit the .tpd files and change from the previous Eclipse to the new Eclipse
    1. There are two .tpd files in releng, both must be edited
      1. org.eclipse.triquetrum.python.rpc.platform.tpd and
      2. org.eclipse.triquetrum.target.platform.tpd
    2. For both files update
      1. The orbit number for the Eclipse release, see https://download.eclipse.org/tools/orbit/downloads/
      2. the Eclipse version number (ex: change 2019-09 to 2020-03)
  2. Right click on each .tpd file and select 'Create Target Definition File', which will create the .target file
  3. Right click again on the org.eclipse.triquetrum.target.platform.tpd file and select 'Set Target Platform' (Or open the .target file that was just created and set the target platform there)

Check for other instances

Eclipse New Version Download

Check out a clean tree and search for the previous Eclipse:

Check for Eclipse and Orbit versions in features/org.eclipse.triquetrum.workflow.rcp.feature/feature.xml

Migrate EMF

Periodically, the EMF files need to be updated.

See 'Maybe a migration is needed' warnings in the log

The .view files in plugins/editor/org.eclipse.triquetrum.workflow.model.viewmodel/viewmodels need to be updated.

To do this, EMF needs to be installed via Help -> Install New Software. It is not quite clear what parts of EMF needs to be installed, try

  • EMF - Eclipse Modeling Framework SDK
  • EMF Forms SDK

When you click on the .view file, then you should be prompted to migrate the file.

If you get an error, then the line number of the error might be in the message. For example, below the error was in line 28:

Update Tycho

  1. Review the Tycho Release_Notes and find the latest released version of Tycho.
  2. Edit pom.xml and update tycho-version.

New Eclipse Version Windows

Testing

  1. Go to the org.eclipse.triquetrum.repository/Triquetrum.product file and select Run.
    1. The new Eclipse version should appear in the splash screen
  2. Exit Eclipse and run 'mvn clean verify'
  3. Test out the installer, which will be in releng/org.eclipse.triquetrum.repository/target/products
