Error in setting JAVA_HOME

Question

I have recently downloaded Maven and followed the instructions given on this this page. I already have ant installed on my machine. Now, if I want to verify that Maven is installed perfectly or not it is giving me error that JAVA_HOME is not set correctly, but same works perfectly fine for ANT.

For Maven I tried :
1. open cmd
2. type mvn -version
3. Error appeared :
C:\Users\Admin>mvn -version

ERROR: JAVA_HOME is set to an invalid directory.
JAVA_HOME = "C:\Program Files\Java\jre7\bin"
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation

For ANT I tried and worked :
1. open cmd
2. type mvn -version
3. Apache Ant(TM) version 1.9.1 compiled on May 15 2013

I went to the directory to check that java.exe is actually there in that directory or not and it was there. I checked the environment variables they set fine. I restarted the system and checked again but same problem. Please let me know what am I missing.

try this.. `C:\ YourFolder >set path=C:\Program Files\Java\jdk1.7.0_09\bin;`, in this case, my jdk version is `1.7.0_09` **OR** you can looked out [this question](http://stackoverflow.com/questions/7709041/javac-is-not-recognized-as-an-internal-or-external-command-operable-program-or/16562626#16562626). Welcome to [StackOverFlow](http://stackoverflow.com/).. ^^ — Ahmad Azwar Anas, Jun 26 '13 at 08:53
With Maven, your JAVA_HOME must NOT CONTAIN the "bin", just ...\jdk1.7.0_09\ is enough. — Andiana, Mar 02 '17 at 02:35
If you did everything correctly and it still doesn't work, try **restarting** your machine — , Mar 31 '20 at 13:14

JAVA_HOME should point to jdk directory and not to jre directory. Also JAVA_HOME should point to the home jdk directory and not to jdk/bin directory.

Assuming that you have JDK installed in your program files directory then you need to set the JAVA_HOME like this:

JAVA_HOME="C:\Program Files\Java\jdkxxx"

xxx is the jdk version

Follow this link to learn more about setting JAVA_HOME:

JAVA_HOME = C:\Program Files\Java\jdk(JDK version number)

Example: C:\Program Files\Java\jdk-10

And then restart you command prompt it works.

Just remember to add quotes into the path if you have a space in your path to java home. C:\Program Files\java\javaxxx\ doesn't work but "C:\Program Files\java\javaxxx\" does.

Ahhhh I see. Just wanted to leave this here since I ended up experiencing the problem with the answer above from Ruchira Gayan. "JAVA_HOME should be like this JAVA_HOME=C:\Program Files\Java\jdk1.7.0_07" And I had to wrap the path with quotes. But comment noted. Will come back when I have any questions. – jonorri Jun 09 '14 at 15:01

The JAVA_HOME should point to the JDK home rather than the JRE home if you are going to be compiling stuff, likewise - I would try and install the JDK in a directory that doesn't include a space. Even if this is not your problem now, it can cause problems in the future!

You are pointing your JAVA_HOME to the JRE which is the Java Runtime Environment. The runtime environment doesn't have a java compiler in its bin folder. You should download the JDK which is the Java Development Kit. Once you've installed that, you can see in your bin folder that there's a file called javac.exe. That's your compiler.

JAVA_HOME should point to the home jdk directory and not to jdk/bin directory.

Make sure you have JDK installed in your computer and then you need to set the JAVA_HOME like this:

JAVA_HOME="C:\Program Files\Java\jdk" + "Your current installed version of jdk in your system"

After installing java , you have to make two changes in environment variables .

JAVA_HOME : which should point to jdk installation directory (not including bin) .
Path : Which will put the bin on the path .

if the error is which respect to JAVA_HOME , try below :

Ensure you have mentioned the directory path correctly .
JAVA_HOME value ending with semicolon could be the ERROR sometimes.If you are not able to remove semicolon from environment, try using cmd as below

set JAVA_HOME = [path of you jdk installation directory ]
