"Please ensure you have JAVA_HOME points to JDK rather than JRE" message
I have java installed
aaa@ubuntu:~$ whereis java
java: /usr/bin/java /usr/bin/X11/java /usr/local/java /usr/share/java
aaa@ubuntu:~$ whereis javac
javac: /usr/bin/javac /usr/bin/X11/javac
and etc/profile
JAVA_HOME=/usr/local/java/jdk1.7.0_17
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
JRE_HOME=/usr/local/java/jre1.7.0_17
PATH=$PATH:$HOME/bin:$JRE_HOME/bin
export JAVA_HOME
export JRE_HOME
export PATH
However, when I run Android Studio, it says:
tools.jar in not in Android Studio classpath. Please ensure you have JAVA_HOME points
to JDK rather than JRE.
How do I fix it?
update
sudo update-alternatives --get-selections | grep ^java
java manual /usr/local/java/jre1.7.0_17/bin/java
javac manual /usr/local/java/jdk1.7.0_17/bin/javac
javaws manual /usr/local/java/jre1.7.0_17/bin/javaws
java -version
java version "1.7.0_17"
You have to use the jre version in the jdk, you can do so by executing
sudo update-alternatives --set java /usr/local/java/jdk1.7.0_17/jre/bin/java
sudo update-alternatives --set javaws /usr/local/java/jdk1.7.0_17/jre/bin/javaws
Normally this can be done by using update-java-alternatives
with a .jinfo
file, but for some reason you can't find them on your system.
