Hello

I faced the same Issue
In Liferay 7.3 can be used only
compileOnly group: "com.liferay.portal", name: "release.portal.api" instead of a lot of jar such in old Liferay version and that cause IDE wired issue

to solve this issue

and then Upgrade gradle Version
gradle =>wrapper => gradle-wrapper.properties

Upgrade Gradle Workspace on file settings.gradle
classpath group: "com.liferay", name: "com.liferay.gradle.plugins.workspace", version: "3.4.2"

then upgrade any module using the old config at build.gradle
such as

compileOnly group: "com.liferay.portal", name: "com.liferay.portal.kernel"
compileOnly group: 'com.liferay', name: 'com.liferay.petra.function'
and use

compileOnly group: "com.liferay.portal", name: "release.portal.api"

last you must clear old jar and used release.portal.api
open cmd and go to workspace folder then you will find gradlew.bat
run this command
gradlew.bat clean
to clean the project

and this issue solve

I can confirm. Experiencing the exakt same thing with liferay IDE Version: 3.9.0.202010130127-ga1 and JDK11.0.8. Default install nothing changed and get errors if i dont use days to find what i need to put in gradle.build to get it to work.

Hello Lawrence Lee,

I have tried this all (checked installed JREs/clean/rebuild) on multiple workstations with the same result.

Ashley Yuan created an issue for this problem which seemed fixed 2 days ago...
https://liferay.dev/blogs/-/blogs/new-installers-and-ide-3-9-0-ga1-released?scroll=_com_liferay_blogs_web_portlet_BlogsPortlet_discussionContainer

The issue: https://issues.liferay.com/browse/IDE-4902

I havent tried it since then.

Actually, can you check a few different JDK settings in your eclipse?

Preferences > Java > Installed JREs

Preferences > Gradle > Java Home

Make sure these point to the correct JDK.

I dont think that this is an issue with the JDK. I was able to follow your steps with Zulu11.43+21-CA

Can you try a project clean and then build again?

Hello,

I have changed my JDK version from zulu11.35.13-ca-jdk11.0.5-win_x64 to zulu8.44.0.11-ca-jdk8.0.242-win_x64 it seems that this fixed my issues with these error markers.

Is working with JDK zulu11.35.13-ca-jdk11.0.5-win_x64 an issue?

Are there any JDK versions that I should or sould not use while working/developing with liferay eclipse?

best regards and thanks for your help.

Hi,

What version of eclipse are you using? Also, what version of JDK do you have selected?

This works for me with eclipse 2020-09 and JDK 8 and 11. If i upgrade my workspace to Gradle 6, then it'll work with JDK 14.

Hope this helps!

I am still getting these error markers with fresh generated modules.
My goal is to upgrade some other modules from 7.1/7.2 to the new liferay 7.3 version.

So like Olaf said here :

It might be that the dependency I'm listing is already contained in the release.portal.api dependency - I've not yet started a new project on 7.3, only ported existing ones forward that explicitly declared the modules they depend on.

If I remove the 'compileOnly group: "com.liferay.portal", name: "release.portal.api"' import and use every dependency import directly on its own I dont get these error markers anymore.

But is this the way to go now? I thought that the single build gradle line 'compileOnly group: "com.liferay.portal", name: "release.portal.api"' would solve importing every single dependency manually or it has all dependencies in it for the fresh generated module?

Can anyone confirm that other people are having similar issues with those error markers? I am worried that I have a problem in my IDE/workstation and this issue isnt an issue at all?

I have tried to fix these error markers with no success.
I am completely lost now. I dont know how to get rid of these. I tried to reinstall my IDE and everything.

I dont know what is going on.
I am sorry to say this but the dependency management with liferay and the liferay IDE is very unclear for me. I dont even know if this is a dependency issue or a bug/error in my IDE.

The craziest part is that my test module is working fine after I deploy it. But still the IDE shows these error markers on many lines of the generated code.

Has anyone had similar experiences developing with this IDE version (3.9.0.202010130127-ga1) and Liferay Portal CE 7.3.5ga6?

Hello Olaf,

thanks for your answer. If I try to organize my imports nothing happens.

The build.gradle was auto generated by the IDE (create new liferay module project) and currently it looks like this:

dependencies {
	compileOnly group: "com.liferay.portal", name: "release.portal.api"

	cssBuilder group: "com.liferay", name: "com.liferay.css.builder", version: "3.0.2"
}

Why would the IDE generate a module that hasnt all dependencies in its build.gradle file?
I tried to add the dependency but it still shows the same error markers.

You're either missing an import (hit Ctrl-Shift-O, or "organize imports" from context menu) in the source file in question. Or you're missing a dependency in your build.gradle file.

E.g.

compileOnly group: "org.osgi", name: "org.osgi.service.component.annotations"

Hello together,

currently I am trying to develop for the new Liferay 7.3.5ga6 CE version. I am getting weird IDE error markers and I dont know how to fix them.

What I have done:

I have downloaded the LiferayWorkspacewithDevStudio windows installer and installed it. (Help -> About -> Liferay Developer Studio -> Version: 3.9.0.202010130127-ga1)
After that I have created a new Liferay Workspace Project and checked the download Server bundle checkbox for bundle 7.3.5 ga6 CE.
Then I created a new Liferay Module Project panel-app and deployed it. Everything works fine.

But in the Eclipse IDE I am getting on many lines of code (that was generated by 'create new liferay module project')
errors like:
on line '@Component' 'Component cannot be resolved to a type'
on this import 'import org.osgi.service.component.annotations.Component;' I am getting 'The type org.osgi.service.component.annotations.Component is not accessible'

There are many other similar error markers (The type ... is not accessible). They do not break the module because if I deploy the module it is working fine.

Here is a screenshot from my IDE and these error markers: https://i.imgur.com/hPKDsdl.png

Why am I getting these error markers and how can I fix them?
