Java Shell文件在手动运行时工作，但在CRON中运行时失败

我有一个shell文件（compile.sh），它编译后运行一个java程序。当我在AIX服务器上手动运行它时，它会工作，但当我通过CRON运行它时，它会给我一个错误

compile.sh：

/usr/java6/bin/javac  -classpath :.:/usr/jdk/commons-net-3.0.1.jar:/usr/jdk/classes12.jar:/usr/jdk/mysql-connector-java-5.1.17-bin.jar:/usr/jdk/jtds-1.2.5.jar:/usr/jdk/mail.jar:/usr/jdk/joda-time-1.6.2.jar:/usr/jdk/commons-codec-1.4.jar:/usr/jdk/commons-logging-1.1.1.jar:/usr/jdk/httpclient-4.1.1.jar:/usr/jdk/httpclient-cache-4.1.1.jar:/usr/jdk/httpcore-4.1.jar:/usr/jdk/httpmime-4.1.1.jar:/usr/jdk/mailapi.jar:/usr/jdk/pop3.jar:/usr/jdk/smtp.jar:/usr/jdk/dsn.jar:/usr/jdk/imap.jar -d . daily_transmission.java

编译和运行之前只需更改目录即可：

cd /absolute/path/to/your/project

实际上，

cron

执行用户主目录中的每个作业。因此，最好从shell脚本更改工作目录。甚至可以像在主目录（或根目录）中一样编写查询，方法是指定每个文件和文件夹的绝对路径。

只需在编译和运行之前更改目录即可：

cd /absolute/path/to/your/project
