我有一个 shell 文件 (compile.sh),它编译然后运行一个 java 程序。当我在 AIX 服务器上手动运行它时它可以工作,但当我通过 CRON 运行它时却出现错误。

编译.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

java -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:/urs/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 daily_transmission

错误:

/ttms/its/db/dropez/trans/compile_java.sh
javac: file not found: *.java
Usage: javac <options> <source files>
use -help for a list of possible options
Exception in thread "main" java.lang.NoClassDefFoundError: daily_transmission

Could not find the main class: daily_transmission. Program will exit.

最佳答案

在编译和运行之前更改目录即可:

cd /absolute/path/to/your/project

/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

java -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:/urs/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 daily_transmission

** 更新 **

事实上,cron 从用户的主目录执行每个作业。因此,最好从您的 shell 脚本更改您的工作目录。或者甚至通过指定每个文件和文件夹的绝对路径来编写您的查询,就像您坐在主目录(或根目录)中一样。
