eclipse版本：eclipse-jee-luna-R-linux-gtk-x86_64.tar.gz
jdk版本：jdk1.8.0_20
eclipse安装路径：/home/chimes/eclipse
jdk解压缩路径：/home/chimes/eclipse/jdk1.8.0_20
/etc/profile设置如下：
export JAVA_HOME=/home/chimes/eclipse/jdk1.8.0_20
export JRE_HOME=/home/chimes/eclipse/jdk1.8.0_20/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
之后，进eclipse目录双击eclipse图标，出现报错：An error has occurred. See the log file null
无法打开eclipse
通过终端./eclipse可以进入eclipse，但是终端有如下报错提醒：
