Prior to 2021-? it was possible to install the tools into Eclipse 2020-06 and get WebSphere Application Server to be recognized; Now, WebSphere Application Server is no longer available for ANY recent release of the tools - not sure if there is a release that would work; is there ANY version of Toolkit available for ANY version of Eclipse that still supports WebSphere Application Server ? What are the instructions for doing so? Unfortunatly, Application Server does not work without IBM JDK 1.8

Submitted by Philip Nickoll on Wed, 08/11/2021 - 13:10

AppServer Tools 20.0.0.09 should work with Eclipse 2020-06 with Websphere Application Server, this should be the version you get if you try to install the AppServer tools via Eclipse marketplace. Since Eclipse moved to Java 11 in 2020-09 you are right in sticking with Eclipse 2020-06. 

Have you tried that combo? If so can you show me your installed software list for the AppServer tools (Help -> Install New Software -> What is already installed)

I wonder if somehow the versions of installed software got mixed up, it is safer to start from a clean Eclipse installation if possible.

Dragging the "Install" button/icon and dropping it on the eclipse Workbench makes it easy to install the necessary components, but could we also get a set of written/documented steps what we need to install as the pre-requisites/dependencies, so that if that "Install" icon is gone for whatever reason, we will still know what to do? Thanks.

When trying to download the tools from market place, the following error comes up: No repository found at: public.dhe.ibm.com/ibmdl/export/pub/software/websphere/wasdev/updates/wdt/2021-03_comp/.

(I have deliberately removed http in above url because i cannot post here with it..!)

I have been trying since three days but no luck..! Is there any alternate workaround for this ?? PS: The above URL is accessible from browser. We can see the repository there but the issue is only when trying from eclipse marketplace

Submitted by Vlad Troyan on Mon, 10/12/2020 - 15:03

While team works on solution, there is workaround available
Search this issue on github "Eclipse v4.17 (2020-09) + WDT v20.0.0.9 = Unresolved requirement "com.sun.jdi"
and take a look on comments

Tried to use Eclipse 2019.12 with IBM Liberty Developer Tools (19.0.0.12) and I am getting the following error:
"[ERROR] Could not find goal 'install-apps' in plugin io.openliberty.tools:liberty-maven-plugin:3.1 among available goals undeploy, install-feature, dev, test-stop, dump, display-url, java-dump, debug, start, run, status, create, clean, stop, compile-jsp, test-start, uninstall-feature, install-server, package, deploy, configure-arquillian -> [Help 1]"

It seems that the "install-apps" goal is not used anymore by maven plugin 3.0/3.1

Hello,

  • I downloaded libertytools-update-site_19.0.0.3.v20190326_1423.zip, wlp-webProfile8-java8-win-x86_64-19.0.0.3.zip and spring-tool-suite-3.9.8.RELEASE-e4.11.0-win32-x86_64.zip
  • Installed liberty server adapter in STS.
  • Created a spring boot project with packaging option war. (Spring boot version 2.1.4)
  • Created a new server using wlp-webProfile8-java8.
  • If I open on add remove options of liberty server the war name is not visible in available options
  • Above steps work fine on my laptop with windows 10 but not working when I connect to RDP which is part of  a RDP farm and my Windows profile is loaded.

 

I get below 3 erros in elcipse error log.

Project facet com.ibm.etools.javaee.cdi has not been defined. It is used in plugin com.ibm.ws.st.core.ext.

Hi, WDT requires to be installed on top of the JEE eclipse pacakges i.e. https://www.eclipse.org/downloads/packages/release/2019-03/r/eclipse-id… .. is it possible for you to try to install on top of that and then add any spring related tools? Rather than using spring-tool-suite-3.9.8.RELEASE-e4.11.0-win32-x86_64.zip as a base.

I managed to make the Libderty Profile working with STS 3.9.8 for spring boot project.  I had to install Dali Java Persistence Tools features.

Specially Dali Java Persistence Tools - JPA Support was missing, If it is missing then we get error:  Project facet jpt.jpa has not been defined Because of which we get other errors.

Dali Java Persistence Tools are available on update site 2019-03 - https://download.eclipse.org/releases/2019-03 Under last option i.e.    Web, XML, Java EE and OSGi Enterprise Development

Hello, sorry for the late reply but wanted to check if you are still experiencing this issue with the latest WDT release? The issue seems to be related to network problems and might be fixed with a more stable internet connection.

The extra options like
-Web Development Tools
-Services Development Tools

sometimes locks the Maven POM.xml. This makes it impossible for GIT to merge. Can IBM please fix this problem ASAP. It somehow even locks POM.xml even if that project is not using Liberty.
