compile find a bad version of gradle - spring-boot

Question

I use spring boot 2. In a multi java project.
I try to build my main library (no yet java file)
apply plugin: 'java-library-distribution'
plugins {
id 'org.springframework.boot' version '2.0.0.M7'
}
repositories {
mavenCentral()
maven { url "https://repo.spring.io/snapshot" }
maven { url "https://repo.spring.io/milestone" }
}
dependencies {
compile group: 'org.springframework.boot', name: 'spring-boot-starter-data-jpa', version: '2.0.0.M7'
compile group: 'org.postgresql', name: 'postgresql', version: '42.1.4'
testCompile group: 'org.springframework.boot', name: 'spring-boot-starter-test', version: '2.0.0.M7'
}
distributions {
main{
baseName = 'common-model'
}
}
sourceCompatibility = 1.8
tasks.withType(JavaCompile) {
options.compilerArgs = ["-Xlint:unchecked", "-Xlint:deprecation", "-parameters"]
}
In my gradle/wrapper, i have
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.2-bin.zip
error i get
caused by: org.gradle.api.internal.plugins.PluginApplicationException:
Failed to apply plugin [id 'org.springframework.boot']
Caused by: org.gradle.api.GradleException: Spring Boot plugin requires
Gradle 4.0 or later. The current version is Gradle 2.13

Answer 1

It's possible you might be building the project with gradle installed locally instead of using the wrapper i.e. using gradle build instead of ./gradlew build.

Answer 2

These are the steps I took to fix the same problem.
I had a new project with a build.gradle file, but did not have a copy of gradle wrapper in my project directory. I think this caused the default gradle version for my IDE to be used (IntelliJ) and this is an older version.
Gradle was already installed on my system.
Ran "gradle wrapper" in my project directory.
Edited ./gradle/wrapper/gradle-wrapper.properties and made sure "distributionUrl" was pointed at the gradle version I wanted (4.6 in my case).
Reran my build and the correct version was then downloaded and installed. Problem fixed.
I hope this helps someone!
I copied my gradle wrapper folder over from another project, and edited ./gradle/wrapper/gradle-wrapper.properties

Answer 3

I'm running Eclipse 2018-2019/STS 4.0/Buildship Gradle 3.0. I solved the problem by configuring Eclipse > Gradle > Properties.
Specifically:
Eclipse > Gradle > Update Gradle Project >
Error: Spring Boot plugin requires Gradle 4.0 or later. The current version is Gradle 3.4.1
Everything looked OK in Eclipse > Window > Installed Software So I checked my Windows user profile directory:
Directory of C:\Users\paulsm\.gradle\wrapper\dists
06/11/2017 09:14 AM <DIR> gradle-3.3-all
12/07/2018 06:23 PM <DIR> gradle-3.4.1-bin <-- Eclipse using this version
11/01/2018 02:38 PM <DIR> gradle-4.1-all
11/01/2018 02:50 PM <DIR> gradle-4.4-all
12/07/2018 03:02 PM <DIR> gradle-4.8.1-bin
Eclipse > Window > Preferences > Gradle > Gradle distribution > Changed from "Gradle wrapper" => "Specific version: 4.8.1"
Re-ran Eclipse > Gradle > Update Gradle Project => SUCCESSFUL
This effectively ignores the project's local gradle wrapper settings, and ensures that I'll have the "correct* settings for ALL my Eclipse projects going forward.
I can always re-configure Gradle on a per-project basis (reverting back to 3.4.1 or older) if I ever need to.

Answer 4

Another option is to change the Gradle wrapper properties.
Error message:
> Failed to apply plugin [id 'org.springframework.boot']
> Spring Boot plugin requires Gradle 4.4 or later. The current version is Gradle 4.0
Change the distributionUrl value in gradle-wrapper.properties (located in /gradle/wrapper/) from:
distributionUrl=https\://services.gradle.org/distributions/gradle-4.0-bin.zip
to
distributionUrl=https\://services.gradle.org/distributions/gradle-5.0-bin.zip

Answer 5

Open gradle/wrapper/gradle-wrapper.properties and change distributionUrl property to 4.6 version or newer one.
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-bin.zip
