我的操作系统是 windows7.in cmd，我运行：
cd sakai3/3akai-ux
mvn clean install
我有：
[INFO] BUILD SUCCESS
然后我运行：
cd sakai3/nakamura
set MAVEN_OPTS="-Xmx256m -XX:PermSize=256m"
mvn clean install
我收到了这个错误：

然后我安装 org.sakaiproject.nakamura.ojdbc.jar 在文件夹 D:\sakai3\nakamura\contrib\oracle-jdbc 下使用此命令：
mvn deploy:deploy-file -DgroupId=org.sakaiproject.nakamura -DartifactId=org.sakaiproject.nakamura.ojdbc -Dversion=1.4.2 -Dpackaging=jar -Dfile=ojdbc6.jar -Durl=url -DrepositoryId=repositoryId
mvn install:install-file -DgroupId=org.sakaiproject.nakamura -DartifactI
d=com.oracle-jdbc -Dversion=1.4.2 -Dpackaging=jar -Dfi
le=ojdbc6.jar
然后我得到一个新的错误：</p>
