Maven Spring启动编译错误？

Question

I am trying to compile a spring boot project with mvn package command but I am getting this error. I believe I have the JDK 1.7_55 installed.

[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

Here is the output of the javac.

testspring>javac -version
javac 1.7.0_55

And here is the output of maven version.

..\testspring>mvn -v

Answer 1

try the following

Go to

Windows -> Preferences -> Java -> Installed JREs

And check whether it is pointing to your JDK path , if not, click on edit button and put the path you configured your JAVA_HOME enviroment.

And

Go to

Window > Preferences > Java > Installed JREs > Execution Environments

Select JavaSE-1.6 or your required version , click the jdk checkbox on the right.

Then right click on your project in eclipse and select Mavan -> “update project configuration”

Answer 2

Try setting your JAVA_HOME to the location where you have your JDK installed, for example:

export JAVA_HOME=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

Or with newer JDK:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home/

Answer 3

I got the issue because my java is referred to JRE rather than JDk .

I was using spring tool suite.

go to windows->preferences->Java->installedJre's and verify if it's pointed to JRE or JDK

Answer 4

Right click on your project-> goto properties ->Select java build path -> switch to Libraries -> there you have to change jre to jdk

I think this will solve your problem.
