Why I have the error Java is set to an invalid directory when i try to install Maven?

Question

I'm trying to install Maven in order to run selenium junit test and then integrate it in Jenkins

When I run in CMD : mvn -version, I have this:

Error: JAVA_HOME is set to an invalid directory.
JAVA_HOME = "C:\Program Files\Java\jdk1.8.0_11\bin"
Please set the JAVA_HOME variable in your environnement to match the 
location of your Java installation.

When I run java -version, I have this:

java version "1.8.0_20"
Java(TM) SE Runtime Environment (Build 1.8.0_20-h26)
Java HotSPot(TM) 64-Bit Server VM (build 25.20-h23, mixed mode)

Why do I get this error?

Answer 1

PLease go to http://dbc-customs.com/?p=96

1. Download and install Java JDK (minimum 1.7) Jave SE downloads

2. Download Maven Binary from Apache from the Maven Downloads Page or use this direct link for Maven 3.2.1 (Binary zip)

3. Extract zip file to C:\Program Files (x86)\ApacheMaven\apache-maven-3.2.1 (Note: if you select a different directory, please update following steps accordingly)

4. Open the “Environment Variables” in Windows. (WinKey + Pause/Break) > Advanced System Settings > Advanced tab > “Environment Variables…” Button.

5. Add the following variables to the “System variables” section. (Not the “User variables”)

JAVA_HOME
C:\Program Files\Java\jdk1.7.0_51

M2_HOME
C:\Program Files (x86)\ApacheMaven\apache-maven-3.2.1

M2
%M2_HOME%\bin

6. Open the “Path” variable in the System variables section, and add the following at the end of your Path:
;%M2%;%JAVA_HOME%\bin
Note: the semicolon ( ; ) is used to separate values.

7. Open a new command prompt (Winkey + R then type cmd) and run mvn --version

to verify that it is correctly installed.

C:\Users\curtis>mvn --version
Apache Maven 3.2.1 (ea8b2b07643dbb1b84b6d16e1f08391b666bc1e9; 2014-02-14T10:37:52-07:00)
Maven home: C:\Program Files (x86)\ApacheMaven\apache-maven-3.2.1

Answer 2

Your configuration should be:

JAVA_HOME = C:\Program Files\Java\jdk1.8.0_11
M2_HOME = C:\Program Files\Apache Software Foundation\apache-maven-3.2.3

Then in your PATH add:

;%JAVA_HOME%\bin;%M2_HOME%\bin

If you need an explanation check this:

For Java

For Maven

Answer 3

Please set the JAVA_HOME variable in your environnement to match the location of your Java installation. This is clearly saying that your value to JAVA_HOME is wrong.
Change your JAVA_HOME with following value.

JAVA_HOME = "C:\Program Files\Java\jdk1.8.0_11"

PATH and JAVA_HOME are two different environment variables. JAVA_HOME is java installation directory. Where as PATH for Java is location of javac.exe,java.exe like executables so it is upto %JAVA_HOME%bin.

Answer 4

set JAVA_HOME to C:\Program Files\Java\jdk1.8.0_11 without the \bin and in the path put %JAVA_HOME%\bin
