Unable to locate tools.jar
Solution 1
A JRE doesn't have a tools.jar, you need a JDK. Set your JAVA_HOME and PATH variables so that they point to a JDK, not a JRE.
Solution 2
I had similar issue and got solved by doing following ,
1) set JAVA_HOME as C:\Program Files (x86)\Java\jdk1.7.0\
2) ANT_HOME as F:\ant\apache-ant-1.8.4-bin\apache-ant-1.8.4
3) add both to 'path ' in system variables
Solution 3
Please make sure that you are pointing to JDK and not a JRE. For example, you should set JAVA_HOME as "C:\Program Files\java\jdk1.6.0_26" and have %JAVA_HOME%\bin in your system path.
Solution 4
I had to copy C:\Program Files\Java\jdk1.6.0_26\lib\tools.jar to C:\Program Files\Java\jre6\lib\ext
Thanks anyway.
Solution 5
tools.jar comes with JDK, but what happens in your case it looks for it within /Java/jre6. Change JAVA_HOME env var to one of your JDK home.

Unable to locate tools.jarI'm trying to use ant to compile using this command :
ant compile
I don't know if the problem comes from my windows 64bit, or by something else. Because I have java Installed in the 64 & 32 prog files.
I downloaded
apache-ant-1.8.2-bin
and putted it in C:\Program Files\apache-ant-1.8.2I tried to put ant everywhere, I switched also the ENV PATH between java 64 and 32 but everytime I get this error message :
Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre6\lib\tools.jar
I searched for tools.jar in the ant lib folder, in the java 64 and 32, but no trace of it in the system.
What do you think ?

Sean Patrick Floyd almost 13 yearsYou should not do such a thing. A JRE is a JRE and a JDK is a JDK. Don't mix the two, or you'll get strange, non-reproducible behaviour
-
Wassim AZIRAR almost 13 yearsI have the jdk and jre in my %PATH%. you think I should remove the jre ?
-
Art Licis almost 13 yearsI would even suggest removing all of Java installs on your dev machine except for single JDK you will be using :) Unless some of existing product installs don't depend on existing JREs.

Munchies over 9 yearsAdding "C:\Program Files\Java\jdk1.7.0_65" to JAVA_HOME and "C:\Program Files\Java\jdk1.7.0_65\bin" to PATH did the trick. (jdk1.7.0_65 is for JDK 1.7 Update 65 and can vary)
-
Sean Patrick Floyd over 9 years@Munchies actually, it's more elegant to add
%JAVA_HOME%/bin
to path. that way you need to change only one variable when you upgrade -

John over 9 yearsIs Windows the only OS where restarting means you lose your currently open Windows? I just restart the cmd console until I see changes propagated there. Unless of course you've elected to be elegant and some rogue script is overriding your JAVA_HOME path so that it's still pointing at the JRE

JavaTec about 8 yearsFor me, adding JAVA_HOME in the windows classpath/path did not help - rather i had to create a new environment variable - JAVA_HOME within the eclipse and point it to JDK7 - that worked

escalator about 7 yearsIn my case the variable
CLASSPATH
pointing to%JAVA_HOME%\jre\lib
was missing, see stackoverflow.com/a/26640589/2518971
