Java & Maven environment

➜

      ~ which java
    /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java
    ➜  ~ mvn -v
    Apache Maven 3.6.1 (d66c9c0b3152b2e69ee9bac180bb8fcc8e6af555; 2019-04-05T03:00:29+08:00)
    Maven home: /Users/munan/Documents/work/develop/maven/apache-maven-3.6.1
    Java version: 1.8.0_192, vendor: Oracle Corporation, runtime: /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
    Default locale: zh_CN, platform encoding: UTF-8
    OS name: "mac os x", version: "10.16", arch: "x86_64", family: "mac"

It seems that there is no problem with the environment. So where is the problem that caused the build to fail?

回答1:

BigSur added JRE path for some reason and I uninstalled the JRE as I needed the JDK (and not JRE) and it worked.

Go to /Library/Internet Plug-Ins.
Remove the JavaAppletPlugin.plugin directory by executing the rm command as a root user or by using the sudo tool.
Go to /Library/PreferencePanes.
Remove JavaControlPanel.prefpane by executing the rm command as a root user or by using the sudo tool.

I was facing the same issue after updating my Mac to Big Sur! So I set my JAVA_HOME env variable and now everything is back to its business. Open the terminal and hit the below commands to solve it yourself.


$ vim .bash_profile 
export JAVA_HOME=$(/usr/libexec/java_home)
$ source .bash_profile
$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home

Check your java_home by running:

/usr/libexec/java_home -V

BigSur added JRE path for some reason, and higher priority than yourself JDK。

Heres my solution:

First:

/usr/libexec/java_home -V

then maybe you will get:

Matching Java Virtual Machines (2):
    1.8.202.08 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
    1.8.0_202 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

so the second is our's real JDK. Just edit the JAVA_HOME in your bash profile.

vim ~/.zshrc
export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home"
source vim ~/.zshrc
echo $JAVA_HOME

Then it will works! enjoy Bug Sur!

Or you can reinstall jdk8 by this cmd:

brew tap adoptopenjdk/openjdk
brew cask install adoptopenjdk8

回答4:

you JAVA_HOME contains JRE path , Please use JDK (The JDK includes the JRE).

It will resolve your issue.

Hey this is coming in the error [ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

you have to switch to openJdk to do maven clean and install 1st you have to download it you can find it easily. In eclipse you can right click on the project then build path then set the openJDK in libraries tab. After this these error will not come but after each FMP it may switch back to jre. Hope the help
