The plugin don't support maven jar project
Submitted by Danilo Berardi on Mon, 09/02/2024 - 12:45
Running the war project the online server statrs without problem, but the jar maven project when started recompiles the files by maven and then returns the following message:
Skipping module ReGisStub-1.0 which is not included in this invocation of dev mode.
The project is a springboot type version 3.3.1.
Is there a workaround?
Liberty Maven Plugin with Spring Boot
Submitted by Scott Kurz on Mon, 09/23/2024 - 13:46
In reply to The plugin don't support maven jar project by Danilo Berardi
Sorry, I just noticed this.
The dev mode in liberty-maven-plugin does not work with a Spring Boot JAR.
The only way to use dev mode with Spring Boot in Liberty currently is to use a WAR packaging type. Some of the details are described in this blog post https://openliberty.io/blog/2024/05/01/spring-boot-3.html . I recognize changing packaging type might not be an option for you though.
Note you should still be able to leverage the Java and server configuration assistance in Liberty Tools even without the ability to launch the app via liberty-maven-plugin dev mode.
If it helps I'll mention too that you can use liberty-maven-plugin to deploy a Spring Boot JAR to Liberty, (just not in dev mode). To use this approach you do need an extra configuration element, it should look something like this:
<plugin>
<groupId>io.openliberty.tools</groupId>
<artifactId>liberty-maven-plugin</artifactId>
<configuration>
<deployPackages>spring-boot-project</deployPackages>
This technique is used in the Liberty Spring Boot guide: https://github.com/OpenLiberty/guide-spring-boot/blob/prod/finish/pom.x… (using the other synonym for this <deployPackages> configuration parm element, <installAppPackages>).

Spring 6 - Eclipse - Ant build - liberty tools compatibility

In reply to Spring 6 - Eclipse - Ant build - liberty tools compatibility by Devanathan Vasu
Yes, you can still get some value from Liberty Tools Eclipse with a project using an Ant build. You can get assistance with Liberty server config (server.xml, bootstrap.properties, server.env). You can also get some assistance for the Jakarta EE 9 APIs via the language server (though you shouldn't expect this assistance to be Spring-"aware").
You would not, however, be able to use the Liberty Dashboard view in Liberty Tools to view and run your app, since these leverage the Liberty Maven/Gradle plugins.
I'll also mention that we don't test for compatibility or coexistence with any Spring Eclipse tooling (e.g. STS), another thing you might be asking about.
Liberty Tool for multiple web applications

How can multiple web application sharing same port no e.g 9080 when using Liberty Tool (like Liberty Developer Tool) ?

In reply to Liberty Tool for multiple web applications by chua chua
Good question.
It's true that most of our tooling and documentation centers around a single application per server, and so, though we don't prevent you from using more than one app per server, the approach here isn't obvious.
So, it is possible to use the code assistance outside of a single, tooling-executable project. E.g you can use the server.xml code assistance to get completions for adding elements/attributes and Jakarta API quick fixes even without the ability to use a tooling-integrated deployment and server execution. True, this is less than a first-class experience but can still be helpful.
Another path you could take, assuming you're using Maven, requires a bit of setup work on your part.
You could create a multi-module project with a 'pom' module which will hold your server.xml configuration (and integration tests) and declare dependencies on your other modules. See here, https://github.com/OpenLiberty/ci.maven/issues/1475#issuecomment-156908… for some more details.
Please feel free to let us know your thoughts and feedback in this area.

suppoerted dynamic web module version
Submitted by Nobuhiro Demura on Wed, 08/23/2023 - 20:37
Thank you for your updating plugin.
I am creating a dynamic web project which is going to use jakartaee v9
Set target runtime to "Liberty Runtime"
I want to specify 5.0 for "dynamic web module version",
But I cannot select anything higher than 4.0.
We guess that the cause is as follows.
com.ibm.ws.st.jee.core_1.0.605.v2021-06-29_1604.jar/plugin.xml
There is no description of version 5.0 or higher in the following places.
<extension point="org.eclipse.wst.common.project.facet.core.runtimes">
<runtime-component-type id="com.ibm.ws.st.runtime.servlet"/>
<runtime-component-version type="com.ibm.ws.st.runtime.servlet" version="4.0"/>
<supported>
<runtime-component id="com.ibm.ws.st.runtime.servlet" version="4.0"/>
<facet id="jst.web" version="2.2,2.3,2.4,2.5,3.0,3.1,4.0"/>
<facet id="jst.webfragment" version="3.0,3.1,4.0"/>
</Support>
</extension>
Is there a workaround for the above issue. Or is there an update planned?
Re: suppoerted dynamic web module version

In reply to suppoerted dynamic web module version by Nobuhiro Demura
There is not an update planned since you don't need one to use the (new) Liberty Tools IDE feature. In Liberty Tools we take a different approach than the older Liberty/WebSphere Eclipse IDE tooling. Rather than providing Liberty implementations for constructs like the Target runtime to support things like the Publish operation and management through the Servers view, as in the older Liberty/WebSphere Developer Tools features, we use a different approach.
For Liberty Tools, we assume the use of a Maven or Gradle project. Compilation is performed against normal Maven/Gradle dependencies and the Liberty Maven and Gradle plugins manage installation of the Liberty runtime and deployment of your application to this runtime.
So using a Jakarta EE 9-level feature like Jakarta Servlet 5.0 simply requires you to use a Maven/Gradle project with a recent version of the corresponding Liberty Maven/Gradle plugin, a valid dependency in your pom.xml/build.gradle, and the servlet-5.0 feature in your server.xml.
Managing Liberty servers
Submitted by Ross Bender on Thu, 07/13/2023 - 10:09
Based on the above comments that plugin is a next-generation version of IBM Liberty Developer Tools, I installed it to compare with the other. However, after doing so I am not able to see or create Liberty server profiles under the "Servers" view.
We don't integrate any Liberty dependencies (Maven/Gradle) or configuration in our application; we deploy our app to Liberty using the Servers pane in Eclipse. Is this be supported in this plugin?

In reply to Managing Liberty servers by Ross Bender
Ross, thanks for your question. Though Liberty Tools is indeed designed as a next-generation version of IBM Liberty Developer Tools, we do not provide the equivalent function in the same manner. First and most importantly, with Liberty Tools we assume you're using a Maven or Gradle project configured with either the Liberty Maven or Gradle plugin. Most Liberty projects are using Maven or Gradle these days, but if not, you would first need to convert your project to Maven or Gradle to make use of Liberty Tools. With Liberty Tools there is no server under the Servers view; the Liberty server is "embedded" in the Liberty Maven or Gradle plugin. Also there is no "Publish" operation; the Liberty Maven/Gradle plugin deploys the application to the plugin-managed Liberty server.

In reply to Managing Liberty servers by Ross Bender
I believe it is.
In Liberty Tools for Eclipse plugin, when you select 'Servers' view and try to create a Liberty server, you should see 'WebSphere Application Server Liberty Extended Tools' under 'IBM'. After you installed it, you should see the same functionality like 'IBM Liberty Developer Tools' provides.
You don't really need Maven/Gradle at all, but I suggest everyone should try Maven/Gradle to let your development environment more friendly.

In reply to Re: Managing Liberty servers by Mark Su
Let me clarify, (I know the naming involved is confusing). The Liberty-related entry in the 'Servers' view has nothing to do with the "Liberty Tools" feature supplied by this particular Eclipse Marketplace item. It might though be something you are getting from the <a href="https://marketplace.eclipse.org/content/ibm-liberty-developer-tools">IBM Liberty Developer Tools</a> feature install.
Like I mentioned in my own reply comment, the "Liberty Tools" feature does indeed assume the use of Maven/Gradle, (though the "Liberty Developer Tools" feature does not, which I think is what you noted).
While there could be some amount of value potentially in installing both "Liberty Tools" and "Liberty Developer Tools" in a single Eclipse installation (e.g. to get code assistance for Jakarta EE 9/10 APIs), we don't really document this. The combination could get confusing because the underlying implementations are using different approaches and are not especially integrated.

You can actually install the current version (v0.8.0) of Liberty Tools Eclipse on 2023-03 (v4.27) and it will work fairly well. We are currently working on a Liberty Tools version that will build upon v4.27 and take advantage of the base platform even better.
