I'm having various Gradle problems after a new clean Eclipse install.
They seem to be associated w/ this "Problem" message:

I've already tried deleting .gradle & "Gradle->Refresh Gradle Project".
I've also tried this:
stackoverflow
My Java install is clean:
java version "16.0.1" 2021-04-20
& confirmed Eclipse is pointing to it ("Preferences->Java->Installed JREs").
Installation details:
Buildship: Eclipse Plug-ins for Gradle 3.1.5.v20210113-0929
Eclipse IDE for Java Developers 4.20.0.20210612-1200

Thanks to LMC. I changed the project prefs->Gradle from Wrapper to Specific=7.1.1 :
I have updated my gradle-warpper.properties file with
distributionUrl=https://services.gradle.org/distributions/gradle-6.4.1-bin.zip
from
distributionUrl=https://services.gradle.org/distributions/gradle-5.6.2-bin.zip
and refresh the gradlew project in eclipse. It's build successfull
Note : Java 11 version is installed in my machine
Change your gradle.properties file
distributionUrl=https\://services.gradle.org/distributions/gradle-7.0.2-all.zip
And build.gradle file
dependencies {
classpath 'com.android.tools.build:gradle:7.0.0'
}
In my case, it was because Eclipse was running upon a JVM that was different from the one used by my local Gradle.
I edited the eclipse.ini file so that Eclipse would run on the same JVM as my local Gradle (i.e. the one pointed by JAVA_HOME) and it worked!
when I'm using mvn install, and found that the number of compiling sources is different from that built from eclipse project build.
that is when compiled from mvn there's info message telling
[INFO] Compiling 359 source files to E:\workspace\project\target\classes
but when using eclipse-> project -> build project, there's over 400 classes, that means some classes are not compiled when using maven.
Is there anyone ever met similar problem?
ps: the tried with JDK 1.7, JDK1.8 and maven 3.2.1, 3.3, 3.1.1 and meet the same problem.
I began to get errors after downloading Nodeclipse and creating a Gradle project with New Gradle Project -- sample project "Java Quickstart". Whenever I re-open Eclipse, I get this error:
"Updating Maven Dependencies" has encountered a problem. An internal
error occurred during: "Updating Maven Dependencies".
org/eclipse/m2e/core/internal/project/registry/ProjectRegistryRefreshJob$1
I have never used Maven, but I tried to investigate the error. When I try to open Preferences > Maven, or most (but not all) of its subfolders, I get:
Unable to create the selected preference page. An error occurred while
automatically activating bundle org.eclipse.m2e.core.ui (545).
I looked on Maven Central and there is no m2e folder in org/eclipse. I also looked in Eclipse/features for pom.xml files and I have folders starting with org.eclipse.m2e, but no org.eclipse.m2e.core.ui.
Edit:
I created a new workspace and got the same error message as soon as I created a New Gradle Project based on Java Quickstart sample project. I did this twice and the second time Eclipse logged an error. Some relevant lines from the stack trace:
Exception:org.osgi.framework.BundleException: Exception in org.eclipse.m2e.core.internal.MavenPluginActivator.start() of bundle org.eclipse.m2e.core
Exception:java.lang.NoClassDefFoundError: org/eclipse/m2e/core/internal/project/registry/ProjectRegistryRefreshJob$1

First try to build your project from command line.
Enide 2015 by Nodeclipse has built-in Terminal Ctrl+Alt+T
run gradle build
or right-click build.gradle Run as -> gradle build
Then see and think
You are building with Gradle, so don't look at Maven preferences, but Gradle one.
Possibly you confused Gradle and Maven and made wrong preferences, you can try again in new workspace.
I'm using a maven plugin in my POM file. When I build the project, I get an error:
`[ERROR] Failed to execute goal br.com.ingenieux:jbake-maven-plugin:0.0.9:generate (default-cli) on project uts-documentation: The plugin br.com.ingenieux:jbake-maven-plugin:0.0.9 requires Maven version 3.1.1 -> [Help 1]`
My embedded maven version is 3.0.4. How can I update to the required version without installing a separate instance of maven (would like to avoid that if possible)?
Upgrading to a more recent Eclipse version will bring an updated embedded version of Maven. For example the Eclipse Luna installation that I am running has Maven 3.2.1 embedded.
I add sbt eclipse plug-in .First I created the project named hello the in project directory i created a file named plugins.sbt and add this line in it

and after the sbt> I typed eclipse then it created the project for eclipse
when I open eclipse it gives me error message

Are you using Eclipse Luna for Java Developers (as opposed to Eclipse Classic) AND Scala IDE 4.0 milestone 3? There is a known issue (solved in the nightly builds since then), reported on the mailing list here.
You can "fix" it by either upgrading the Scala plugin to a nightly build (they're pretty stable), or going with Eclipse Classic instead.
