No compiler is provided in this environment with jenkins

Question

I'm getting this error when I try a Jenkins build on a maven project:

No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

The java and maven plugin are installed automatically, after several research, I couldn't find a solution!

Does anyone have ever face this issue?

Answer 1

Go To Jenkins -> Manage Jenkins -> Global Tool Configuration -> JDK. Provide path to the JDK under JAVA_HOME field.

Answer 2

First make sure the your Job in Jenkins doesn't use the "default Jdk" by going to the job: Press on Configure - > and roll to the JDK section - and make sure you have JDK configure instead of Default.

if you don't have it - go back to Jenkins - > Manage Jenkins -> Configure System - > Jdk and map your Jdk Root for Jenkins.

when you finish that - go back and choose your map JDK - and everything will work.

Answer 3

Go To Jenkins -> Manage Jenkins -> Global Tool Configuration.

Now click on "JDK installations.." under JDK

Uncheck Install automatically

Provide path to the JDK under JAVA_HOME field.

Answer 4

May be this issue is already resolved by now. But I had the same issue recently and I have the following settings in my Jenkins . This happened in my Windows 10 Jenkins installation.

1. Installed JDK at C:\\Java\\Jdk8 and made JAVA_HOME point to this location. Also make sure that PATH env variable has %JAVA_HOME%\\bin.
2. Installed JRE (which comes bundled with Oracle JDK installation) at C:\\Program Files\\Java\\JRE .

3. Jenkins -> Manage Jenkins -> Configure System

4. Jenkins -> Manage Jenkins -> Global Tool Configuration

# javac -version

javac 1.8.0_201

# java -version

java version "1.8.0_201"
Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)

# mvn -v

Apache Maven 3.6.0 (97c98ec64a1fdfee7767ce5ffb20918da4f719f3; 2018-10-24T14:41:47-04:00)
Maven home: C:\apache-maven-3.6.0\bin\..
Java version: 1.8.0_201, vendor: Oracle Corporation, runtime: C:\Java\jdk8\jre
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

I believe the change that fixed the problem was the addition of env variables under Manage Jenkins -> Configure System .

Answer 5

You might not have set JAVA_HOME in Jenkin installed server. Set JAVA_HOME and restart your Jenkin server.

Answer 6

根据您的错误消息，您要么没有安装JDK，要么需要配置 Jenkins 的 CLASSPATH 以指向您的 JDK 安装。

Answer 7

在Jenkins Global Tool配置中给出JDK路径即可，即我们在di中保存jdk文件的路径

Answer 8

IF you don't want to add anythig in Global tools Configuration, add new environment variable java.home in the Jenkins slave configuration as maven detects java.home and not JAVA_HOME .

java.home ---> C:\\Java\\jdk1.8.0_181\\jre

Answer 9

Enter http://localhost:8080/configure. Then go Jenkins Location.

Jenkins Configuration:

Environment variable configuration:
