java - 在 ubuntu 中运行 grails 应用程序时无法找到 java 编译器 com.sun.to

Question

我尝试了使用此名称的不同修复程序。但没有工作。

我在 printenvi 下有以下内容。

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/root/bin:/home/thinkvidya-kiran/programs/jdk1.6.0_45/bin:/home/thinkvidya-kiran/programs/jdk1.6.0_45/bin:/home/thinkvidya-kiran/programs/james-2.3.2/bin:/home/thinkvidya-kiran/programs/grails-2.1.1/bin
PWD=/usr/lib/jvm
JAVA_HOME=/home/thinkvidya-kiran/programs/jdk1.6.0_45

尝试过

sudo ln -s /path/to/jre*/bin/java /usr/bin/java

java 和 javac 给我正确的输出。我试着把 -vm 东西放在 eclispe.ini 中。不适合我它给出以下错误。

Answer 1

我在使用最新版本的 Grails 2.4.3 的 Debian 中遇到了同样的问题。我在类路径中添加了 jdk tools.jar 以克服错误。

在 Debian 中我必须这样做

export CLASSPATH=/usr/lib/jvm/java-7-openjdk-amd64/lib/tools.jar

在 Windows 中，您必须找到 tools.jar 并将其添加到 CLASSPATH 环境变量中。
