[英]Environment Path - Terminal OSX
我可以直接在終端中運行java -classpath命令而不會出現問題,但是一旦我嘗試在cron中執行它,就會拋出此錯誤:
Usage: java [-options] class [args...]
(to execute a class)
or java [-options] -jar jarfile [args...]
(to execute a jar file)
where options include:
-d32 use a 32-bit data model if available
-d64 use a 64-bit data model if available (implies -server, only for x86_64)
-client to select the "client" VM
-server to select the "server" VM
-jvm is a synonym for the "client" VM [deprecated]
-hotspot is a synonym for the "client" VM [deprecated]
The default VM is client.
-cp <class search path of directories and zip/jar files>
-classpath <class search path of directories and zip/jar files>
A : separated list of directories, JAR archives,
and ZIP archives to search for class files.
-D<name>=<value>
set a system property
-verbose[:class|gc|jni]
enable verbose output`
研究告訴我,這可能是環境問題嗎? 使用Terminal vs cron時如何知道我的路徑?
我正在直接從cron調用Java,crontab類似於:
0 3 * * * * java -classpath /Users/tb582/Desktop/sample1.jar:/Users/tb582 ...
只需在cron中指定整個路徑即可:
輸入“哪個java”
應該輸出類似以下內容:
/usr/bin/java
