Getting the version from jar file

Hi,

I am trying to retrieve the "Implementation version" from one of the .jar file
The command which tried is as below.

Code:
find /usr/local/platform  -name "platform.jar" -exec zipgrep "Implementation-Version:" '{}' \;|awk -F ': ' '{print $2}'

I am able to get the version as below

Code:
2.9.0-29

But the problem is the above command is not terminating naturally. I have to forcefully exit the command to return to the shell terminal.
On extracting the .jar file there is a MANIFEST file and "Implementation-Version" is written inside the MANIFEST file.Please help in getting the Implementation version from the jar file.

Jar File Search!

Hi vgersh99, Iam sorry for that. In future, I will start new threads for different topics. Assuming that we don't know what the name of the jar file, we are searching for is, do we have any way, of finding a string or a file in it. Is there any Unix command for it? thanks. (2 Replies)

NAME
Maven - Installs a jar into /usr/share/maven-repo. SYNOPSIS
mh_installjar [option]... [pom] [jar] [link]... DESCRIPTION
Installs the jar file in /usr/share/maven-repo, at the correct location for Maven. The jar is copied into the build directory. It can also create additional links to the jar, usually located in /usr/share/java. Where [pom] is the location of the POM associated with the jar to install. GroupId, artifactId and version will be extracted from this file. [jar] is the path to the jar to install, usually located in the build folder. [link] is an additional link to the jar to install, usually there should be a link to usr/share/java/$jar.jar and usr/share/java/$jar-$version.jar to comply with the Java packaging guidelines. Note that there is no need to specify those particular links if the --java-lib option is used. OPTIONS
-h --help: show this text -V --version: show the version -p<package> --package=<package>: name of the Debian package which will contain this jar file -e<version>, --set-version=<version>: set the version for the jar, do not use the version declared in the POM file. -r<rules> --rules=<rules>: path to the file containing the rules to apply when cleaning the POM. Optional, the default location is debian/maven.rules Maven rules are used here to extract the groupId, artifactId and version from the POM file. -l --java-lib: Optional, if given it will install the jar into /usr/share/java to comply with the Debian Java specification. The jar will be installed as /usr/share/java/$name-$version.jar and a versionless link /usr/share/java/$name.jar will point to it, as well as the links installed in /usr/share/maven-repo -n<name> --usj-name=<name>: Optional, the name to use when installing the library in /usr/share/java when --java-lib is used. Defaults to the artifact id found in the POM. -j<version> --usj-version=<version>: Optional, the version to use when installing the library in /usr/share/java when --java-lib is used. Defaults to the version found in the POM. -s --no-usj-versionless: Optional, don't install the versionless link in /usr/share/java. This flag is used only when the -l or --java-lib option is given. -d<path> --dest-jar=<path>: Optional, the destination for the real jar. The other places where the jar appears, in the repository or in the list of links, will be symlinks to this jar. Defaults to /usr/share/java/$name-$version.jar if --java-lib is used, otherwise the jar is installed in the versioned path in the Maven reposi- tory. -c<classifier> --classifier=<classifier>: Optional, the classifier for the jar. Empty by default. -v --verbose: show more information while running -n --no-act: don't actually do anything, just print the results --skip-clean-pom: don't clean the pom, assume that a previous action ran mh_cleanpom with the correct options. mh_cleanpom is run only to extract the groupId, artifactId and version of the jar See also: mh_installpom(1), mh_installsite(1) Maven Repo Helper version 1.7.1 January 2012 MAVEN(1)
