Java package manager is managing libraries
and application regardless platform. We can easily install application and
libraries with help of JPM. Jpm4j is
java implementation which use the power of java so that we can write once and
deploy anywhere.
We can develop java libraries and
application, publish in internet then notify to JPM4J so that we can deploy
from anywhere in any platform with help of Jpm4j.
Install
JPM4J in windows
We have two options to install JPM4J in
windows
Using

We can use –g so that it will be installed in C:\JPM4J directory.
Use following installation jar command in
command prompt
java -jar
biz.aQute.jpm.run.jar -g init
|
Once we run the above command then it will
be created JPM4J directory and it consisted
few sub directories.
Bin
directory having all the commands which we can use
to install java libraries and applications.
Now navigate to bin directory using command prompt then we can use all jpm4j commands.
Use following help command to see all available
commands in JPM4J
jpm help
|
jpm install
The
above command will be used to install other artifacts like java libraries and
applications.
Example:
jpm install bnd
The

7 need JPM4J to install BLADE CLI to develop Liferay 7 modules
and applications. We will going through more details about BLADE CLI in the
next articles.
The following command will install "BLADE CLI"

Setting
PATH Environment variable for JPM4J
In the above case to run JPM4J commands we
need to navigate JPM4J bin directory
then have to use available commands.
To use these commands from anywhere from commands
prompt then we have to set PATH environment variable for JPM4J bin directory.
Go
to system properties
Click on Advanced System Setting then it will open window pop-up
where we need to click on Environment

Now select path variable and click on edit
then add following JPM4J bin path at
end of the string. Finally click on OK then JPM4J path will set as environment variable.
;C:\JPM4J\bin;

Once we completed the above steps, now we
can run commands from anywhere and we don’t need to navigate to bin directory
from command prompt.
