How can I set my Cygwin PATH to find javac

Question

I have a Windows 7 system on which I have installed the latest Java compiler  I also have the latest Cygwin  I want to use the Java compiler from Cygwin s shell  I edited the PATH variable in Cygwin as follows   export PATH  PATH   cygdrive C Program  Files Java jdk1 6 0 23 bin     I can see the javac binary in the above directory  however when I try to compile my   java file I get   javac command not found   Am I doing something wrong in setting the PATH variable like this  Do I have to do something else  I am new to Java and not very familiar with cygwin

If you are still finding that the default wrong Java version  1 7  is being used instead of your Java home directory  then all you need to do is simply change the order of your PATH variable to set JAVA HOME bin before your Windows directory in your PATH variable  save it and restart cygwin  Test it out to make sure everything will work fine  It should not have any adverse effect because you want your own Java version to override the default which comes with Windows  Good luck

Although all other answers are technically correct  I would recommend you adding the custom path to the beginning of your PATH  not at the end  That way it would be the first place to look for instead of the last  Add to bottom of    bash profile  export PATH  quot  cygdrive C Program Files Java jdk1 6 0 23 bin  quot   PATH  That way if you have more than one java or javac it will use the one you provided first

Java binaries may be under  Program Files  or  Program Files  x86    those white spaces will likely affect the behaviour   In order to set up env variables correctly  I suggest gathering some info before starting    Open DOS shell  type cmd into  RUN  box  go to C   type  dir  x  and take note of DOS names  with    for  Program Files    folders   Cygwin configuration   go under C  cygwin home   then open  bash profile and add the following two lines  conveniently customized in order to match you actual JDK path   export JAVA HOME   cygdrive c PROGRA 1 Java jdk1 8 0 65  export PATH   JAVA HOME bin  PATH    Now from Cygwin launch  javac -version  to check if the configuration is successful

To bring more prominence to the useful comment by  johanvdw   If you want to ensure your your javac file path is always know when cygwin starts  you may edit your  bash profile file  In this example you would add export PATH  PATH   cygdrive C Program Files Java jdk1 6 0 23 bin   somewhere in the file    When Cygwin starts  it ll search directories in PATH and this one for executable files to run

as you write the it with double-quotes  you don t need to escape spaces with    export PATH  PATH   cygdrive C Program Files Java jdk1 6 0 23 bin     of course this also works   export PATH  PATH  cygdrive C Program  Files Java jdk1 6 0 23 bin
