How to control LD_LIBRARY_PATH about capsule-maven-plugin HOT 11 CLOSED

DIfferences being the jar that I need to add and two defines. Not sure how you're passing defines that are specified in the plugin into the system properties, but I don't see the command as I would expect them to be.

from capsule-maven-plugin.

Capsule will run the jar like so (scroll right):

[path/to/java] [jvmArgs] [-Djava.library.path=] [systemProperties] [-Dcapsule.app=] [-Dcapsule.dir=] [-Dcapsule.jar=] [-classpath] [mainClass]

You can define the jvm args by customising the manifest entry JVM-Args like so:

<manifest>
  <entry>
    <key>JVM-Args</key>
    <value>-Xmx512m</value>
  </entry>
</manifest>

Just include the above in the <configuration> tag of the plugin section in the pom.xml. See more here.

You can define the system properties similarly like so:

<properties>
  <property>
    <key>PORT</key>
    <value>/dev/ttyACM0</value>
  </property>
  <property>
    <key>WUPASS</key>
    <value>dog</value>
  </property>
</properties>

Just include the above in the <configuration> tag of the plugin section in the pom.xml. See more here.

Regarding the additional dependency you want included in the -classpath, namely, RXTXcomm-2.2pre2.jar, you should simply include that as a dependency in the pom.xml in the normal way. Did you do that?

from capsule-maven-plugin.

If you'd like, you can also share a project that I can play with to help out with your issue.

Ok first problem found. I didn't have the wrapping key spelled correctly. So that wasn't seen.

Should I SEE the -D in the output with : java -Dcapsule.log=verbose -jar weather-1.0.0-SNAPSHOT-capsule-fat.jar ?? Right now I do not.

Second : I can't reference the jar because it's not a Maven accessible artifact. No repo has the particular version I'm using. It's not published that way for the version for the Pi. There IS a version that's available via Maven for the Mac, but that version won't sync up to the JNI lib on the Pi. So I have to use the particular jar (RXTXcomm.jar, the pre version was the jar that I used to test on the Mac).

I'd like to be able to run on the Mac and Pi, but I don't know if that's going to be possible given this issue. But I can live with that, as I can have the dependency for the Mac in the Pom and comment it out when I'm building for the Pi (if I can get the Pi version to work via capsule)

from capsule-maven-plugin.

BTW, with this specified :

 <properties>
    <property>
        <key>Repositories</key>
        <value>central</value>
    </property>
    <property>
        <key>PORT</key>
        <value>/dev/ttyACM0</value>
    </property>
    <property>
        <key>WUPASS</key>
        <value>dog</value>
    </property>
</properties>

I only see : -DRepositories=central in the verbose output.

from capsule-maven-plugin.

Two things: One, just noticed there was a newer version (1.0.5) vs (1.0.3) that I was using. So updated to that. I'm now seeing the -D params.

Second, the ONLY piece I'm unable to configure for is adding the RXTXcomm.jar into the build so that it unpacks as /home/pi/.capsule/apps/weather-1.0.0-SNAPSHOT-capsule-fat/RXTXcomm.jar and then adding /home/pi/.capsule/apps/weather-1.0.0-SNAPSHOT-capsule-fat/RXTXcomm.jar to the classpath.

If I can get that to happen, it'll work.

from capsule-maven-plugin.

Try the latest version (1.1.2) and use fileSets to copy over your local jar:

<fileSets>
  <fileSet>
    <directory>lib/</directory>
    <includes>
      <include>RXTXcomm.jar</include>
    </includes>
  </fileSet>
</fileSets>

So from the above, create a folder called lib in the root folder of your project and dump your RXTXcomm.jar in there. This will tell the plugin to embed it in the capsule jar. Capsule should then pick it up and add it to the classpath automatically (and will also copy it to your /home/pi/.capsule/apps/weather-1.0.0-SNAPSHOT-capsule-fat/RXTXcomm.jar automatically when run too).

from capsule-maven-plugin.

FYI : This really helped! Awesome update, thanks!!

The only thing I'm fighting "slightly" is getting the proper shell
configuration so that the LD_LIBRARY_PATH variable that I'm having to
update for the local library (for the 2nd 1/2 of the RMI library pair) is
set for when the program executes.

I'm trying to figure out how to run the command with gotty (so that I can
run the command and see output via the web page when I want to...)

Hmm I'm not quite what it is you're trying to achieve (I'm unfamiliar with pi & gotty). Perhaps again share the command you're getting and the command you need, so I can try and help...

from capsule-maven-plugin.

Well, gotty web site is here : https://github.com/yudai/gotty

I have a weather station that I have hooked up to a Raspberry Pi.
Standard Unix/Linux install. I do dev work on a Mac or PC and push to it.
Use capsule.io to do the run.

When I invoke the module "inside" gotty, I'm not able to get the
LD_Library_Path set properly.
Basically I'm not sure if Gotty executes a proper "shell" and sources what
I'd expect to get loaded (i.e. what environment is loaded)

I've also looked at tmux ( https://tmux.github.io/ ) and thought about
somehow combining that with gotty.

Basically the goal is to be able to easily monitor the data coming into the
Pi from the weather station (which is an Arduino and a shield connected to
sensors)
The RXTX serial library is used to read the data from the USB connector
(serial port) that feeds into the Pi.

That all works. However when the output from the program that is
monitoring the stream writes data simply to stdout. In the current case, I
redirect it to /dev/null.
Works fine, but if there is an issue, I'd like to see what had happened,
etc. If I drop and re-connect the program, that restarts what was running
on the Arduino, so
I can't find the exact state of things when it went down.

I've had some issues when things hang. I've been slowly working to iron
them out so the configuration stays up 24/7 stable for a long time. I've
had it run for
a week and then maybe 3 weeks continuously. But that was with an earlier
configuration. This one has run for a number of days. I just fixed on
thing (the possibility of
a log file filling up /var/log -- I didn't inspect the file system before I
bounced the Pi, so I'm not 100% sure...dumb me for not checking that...)

This make some sort of sense?

This to me seems out of scope. Let me know if there is something specifically you'd like implemented.
