error: package com.sun.tools.javac.util does not exist

问题

I'm trying to run my play 2.0.1 application on Ubuntu 11.10 and when I visit domain.com:9000 I get this error in terminal:

info] Compiling 4 Scala sources and 6 Java sources to /var/www/clients/client3/web10/sc2lounge/target/scala-2.9.1/classes...

I have JAVA_HOME set like this in my .bashrc file:

JAVA_HOME=/usr/lib/jvm/default-java  #Which is a symbolic link to java-7-openjdk-common
export JAVA_HOME
PATH=$PATH:$JAVA_HOME/bin
export PATH

the output of java -version is:

java version "1.6.0_23"
OpenJDK Runtime Environment (IcedTea6 1.11pre) (6b23~pre11-0ubuntu1.11.10.2)
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)

and the output of javac -version is:

javac 1.7.0_147

My question is, why com.sun.tools.javac.util.List isn't included in the classpath?

回答1:

This class is found in tools.jar, which is not part of the JRE.

回答2:

I got this problem when I try to build kotlin/jvm with gradle, I want to post this to others new to jvm, since jdk-9, there is no tools.jar. setting a classpath is good to go.

JAVA_HOME= path_to_jdk

JRE_HOME= path_to_jre

PATH= ;%JAVA_HOME%\bin;%JRE_HOME%\bin

CLASSPATH=.;%JAVA_HOME%\lib;%JRE_HOME%\lib
