install Groovy in RedHat as4

官方网是这样写的：
1,first, Download a binary distribution of Groovy and unpack it into some file on your local file system
2,set your GROOVY_HOME environment variable to the directory you unpacked the distribution
3,add GROOVY_HOME/bin to your PATH environment variable
4,set your JAVA_HOME environment variable to point to your JDK. On OS X this is /Library/Java/Home, on other unixes its often /usr/java etc. If you’ve already installed tools like Ant or Maven you’ve probably already done this step.

但会出现错误:

解决办法:
#vi /etc/profile

加入GROOVY_HOME
export GROOVY_HOME=”/home1/software/groovy-1.5.0/”

修改CLASSPATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:”/home1/lib/”:$GROOVY_HOME/lib/ant-1.7.0.jar:$GROOVY_HOME/lib/asm-2.2.jar:$GROOVY_HOME/lib/bsf-2.4.0.jar:$GROOVY_HOME/lib/jline-0.9.93.jar:$GROOVY_HOME/lib/mx4j-3.0.2.jar:$GROOVY_HOME/lib/ant-junit-1.7.0.jar:$GROOVY_HOME/lib/asm-analysis-2.2.jar:$GROOVY_HOME/lib/commons-cli-1.0.jar:$GROOVY_HOME/lib/jsp-api-2.0.jar:$GROOVY_HOME/lib/servlet-api-2.4.jar:$GROOVY_HOME/lib/ant-launcher-1.7.0.jar:$GROOVY_HOME/lib/asm-tree-2.2.jar:$GROOVY_HOME/lib/commons-logging-1.1.jar:$GROOVY_HOME/lib/junit-3.8.2.jar:$GROOVY_HOME/lib/xpp3_min-1.1.3.4.O.jar:$GROOVY_HOME/lib/antlr-2.7.6.jar:$GROOVY_HOME/lib/asm-util-2.2.jar:$GROOVY_HOME/lib/groovy-1.5.0.jar:$GROOVY_HOME/lib/mockobjects-core-0.09.jar:$GROOVY_HOME/lib/xstream-1.2.2.jar
