From https://github.com/spring-projects/spring-loaded/issues/98 and worked to me

wget repo.spring.io/libs-snapshot-local/org/springframework/springloaded/1.2.3.BUILD-SNAPSHOT/springloaded-1.2.3.BUILD-SNAPSHOT.jar -O ~/.gvm/grails/2.4.4/lib/org.springframework/springloaded/jars/springloaded-1.2.1.RELEASE.jar

Answer 3

I am running Grails 2.4.3 and also had problems moving from jdk1.8.0_31 to jdk1.8.0_40 and had to go back to jdk1.8.0_31

Loading Grails 2.4.3

SEVERE: Problems copying method. Incompatible JVM?

Answer 4

I updated my springloaded jar to version 1.2.4.BUILD-SNAPSHOT (from 1.2.1) and that resolved the issue. (Latest version can be found in the Spring repo)

1. Go to your local Grails lib directory to find springloaded jar. For me that was /usr/local/Cellar/grails/2.4.4/libexec/lib/org.springframework/springloaded/jars/
2. remove existing 1.2.1 jars (I removed pom file, too, but not necessary)
3. download latest springloaded jar and place into the jars subdir: wget http://repo.spring.io/libs-snapshot-local/org/springframework/springloaded/1.2.4.BUILD-SNAPSHOT/springloaded-1.2.4.BUILD-SNAPSHOT.jar

After doing that, everything works. (Clues used from previous answer: https://github.com/spring-projects/spring-loaded/issues/98)

Answer 5

Step 1 : Download this jar

step 2 : put it into the grails folder: grails-2.4.1/lib/org.springframework/springloaded/jars

should be enough , restart IDE

Two Step To Make it Work

1. Download JDK Lower Version: Install jdk1.8.0_25 from link http://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html#jdk-8u25-oth-JPR. It's the lower version of JDK as grails dont support higher version. Maybe They'll include this in latest version soon.

2. Set Up Environment Variables: Don't forget to change the Enviromental variables for jdk, you have to just edit Path Variables and JavaHome Variable from "C:\Program Files\Java\jdk1.8.0_'LatestVersion'" to "C:\Program Files\Java\jdk1.8.0_25" .
