linux jar命令找不到 -bash: jar: command not found

通过jar命令进行打包或解压包的时候报：-bash: jar: command not found 。JDK环境已经安装。

 

[luopu@TESTWEB1_13 ~]$ echo $JAVA_HOME
/usr/lib/jvm/jre

[luopu@TESTWEB1_13 ~]$ java -version
java version "1.7.0_95"
OpenJDK Runtime Environment (amzn-2.6.4.0.65.amzn1-x86_64 u95-b00)
OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)

JVA_HOME路径下也没找到jar。然后通过find查找jar，查找到JDK安装目录。

[luopu@TESTWEB1_13 ~]$ sudo find / -name jar
/usr/bin/jar
/opt/freeware/old/gradle-2.2/src/language-java/org/gradle/api/internal/tasks/compile/incremental/jar
/opt/freeware/old/jdk1.7.0_79/bin/jar

在/usr/bin目录下创建jar的软连接。

[luopu@TESTWEB1_13 ~]$cd /usr/bin

[root@TESTWEB1_13 ~]#ln -s  /opt/freeware/old/jdk1.7.0_79/bin/jar jar

jra命令找回

[luopu@TESTWEB1_13 bin]$ jar
Usage: jar {ctxui}[vfmn0PMe] [jar-file] [manifest-file] [entry-point] [-C dir] files ...
Options:
    -c  create new archive
    -t  list table of contents for archive
    -x  extract named (or all) files from archive
    -u  update existing archive
    -v  generate verbose output on standard output
    -f  specify archive file name
    -m  include manifest information from specified manifest file
    -e  specify application entry point for stand-alone application 
        bundled into an executable jar file
    -0  store only; use no ZIP compression
    -P  preserve leading '/' (absolute path) and ".." (parent directory) components from file names
    -M  do not create a manifest file for the entries
    -i  generate index information for the specified jar files
    -C  change to the specified directory and include the following file
If any file is a directory then it is processed recursively.
The manifest file name, the archive file name and the entry point name are
specified in the same order as the 'm', 'f' and 'e' flags.


Example 1: to archive two class files into an archive called classes.jar: 
       jar cvf classes.jar Foo.class Bar.class 
Example 2: use an existing manifest file 'mymanifest' and archive all the
           files in the foo/ directory into 'classes.jar': 
       jar cvfm classes.jar mymanifest -C foo/ .
