When running some commands, m2e (Maven eclipse) cannot compile (unable to locate the javac compiler in :)

Bug prompt

Unable to locate the javac compiler in:
C: \ Program Files \ Java \ jre1.6.0 _ 07 \ .. \ Lib \ tools. Jar
Please ensure you are using JDK 1.4 or above and
Not a JRE (the com. Sun. Tools. javac. Main class is required ).
In most cases you can change the location of your Java
Installation by setting the java_home environment variable.

From abovePlease ensure you are using JDK 1.4 or above and
Not a JRE (the com. Sun. Tools. javac. Main class is required)

We can see that m2e requires JDK and JDK 1.4 or later for compilation.

Under the command lineEcho % java_home %

Check that my "java_home" isC: \ Program Files \ Java \ jdk1.6.0 _ 20

I realized that I was using m2e, so my runtime environment should be based on

Eclipse (eclipse also has its own runtime environment by default) is specified, so I only need to modify the runtime environment path specified by eclipse,

Therefore

1. Modify "window --> preferences-> JAVA-> installed jres" in Eclipse ":

Edit the selected JRE or add a new JRE and select it

The location shoshould be "C: \ Program Files \ Java \ jdk1.6.0 _ 20 \ JRE"

Please don't close the "Edit JRE" dialog, continue the second step.

2. Remove the default JRE system libraries and add all the jar inLibFolder, lib subdirectory in% Java_home %/JDK **/JRE/

In the past few days when Maven was used, it has been found that you have installed your project. When such a bug occurs, you need to go to the repository and delete these existing versions.
