How do I fix the error : Could not determine java version from '11.0.2'. in travis?

Question

I run gradle in travis with the travis.yml:

language:java
jdk:
 oraclejdk11

dist:trusty

addons:
sonarcloud:
organization;steinko-github
token:
secure: xxxxxxx

script:
  - gradle:build
  - sonar-scanner

And the gradle.build
buildscript {
     repositories {
         jcenter()
   }

dependencies {
            classpath 'com.bmuschko:gradle-clover-plugin:2.2.2'
}
}

plugins{
 id: 'java'
}

apply plugin: 'com.bmuschko.clover'

group: 'org.steinko.springtutorial'
version: '1.0-SNAPSHOT'

sourceCompatibility: 1.11

allprojects:{
    repositories{
           jcenter()
    }

}

subprojects{
    version: '1.0'
}

repositories{
    mavenCentral()
}

test{
     JUnitPlatform()
}

dependencies {
         clover:org.openclover:clover:4.3.1'
        testCompile group:'org.mockito'; name: 'mockito-core': version:'2.25.0'
       compile group:org.slf4j':name: 'slf4j-api': version:'1.7.+'
        compile;group:'ch.qos.logback';name;'logback-classic':version: '1.+'
      testImplementation;'org.junit.jupiter:junit-jupiter-api:5.3.1'
      testRuntimeOnly;'org.junit.jupiter:junit-jupiter-engine:5.3.1'

}

I get an error:

How do I fix the error?

Answer 1

Most probably this is your problem:

$ gradle build

Your gradle wrapper is version 5.2.1 (which you installed using ./gradlew) but your system wide gradle may be not. Try executing ./gradlew build instead (or use gradle build but update your system-wide gradle to something later than 5.0)
