未能运行grails

Question

我使用CentOS和grails来托管一个web应用程序。我已经在/.bash_profile中设置了以下内容

export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk
export PATH=$JAVA_HOME/bin:$PATH
export GRAILS_HOME=/usr/grails/grails-2.5.6
export PATH=$PATH:$GRAILS_HOME/bin

运行echo $JAVA_HOME

/usr/lib/jvm/java-1.7.0-openjdk

运行echo $GRAILS_HOME

/usr/grails/grails-2.5.6

运行echo $PATH

......other_paths......
/usr/lib/jvm/java-1.7.0-openjdk/bin:
/usr/grails/grails-2.5.6/bin:
......other_paths......

运行java -version

java version "1.7.0_221"
OpenJDK Runtime Environment (rhel-2.6.18.1.el7-x86_64 u221-b02)
OpenJDK 64-Bit Server VM (build 24.221-b02, mixed mode)

最后，当我运行grails --version时，控制台将我抛出以下内容：

我花了一些时间在这个问题上，但仍然无法解决。有什么好建议吗？

Answer 1

看来JVM缺少了一些依赖项。我会卸载/重新安装它。

一些谷歌建议我在这里和其他地方发布文章，建议CentOS附带的JDK和/或JVM专门排除某些项目，因此重新安装可以确保您有一个干净完整的副本。
