Hello,
as written in the subtitle, I wrote a simple plugin RCP with one menu, one command and one handler to execute the command.
Theme is as written that if I execute it in run or debug mode, everything works.

But if I install it, I see menu in "main.menu" and after pushed down the command, nothing happens. Differently from run and debug mode, where it works.

I attach plugin.xml, it.alba.rcp.commands.product and MANIFEST.MF.

I'm using Eclipse SDK

Version: 2019-09 (4.13)
Build id: I20190916-1045

Any help is appreciated. Thanks in advance.

Yuri

Could you please run with `-consolelog` and attach the output here? I noticed that you're including embedded jar files, and a common mistake is that those embedded jars are not actually included in your bundle. Take a look at the the bundle contents and make sure your lib/*.jar files are present. If not, open your MANIFEST.MF then switch to the "Build" tab and ensure they are included for the binary build.

Hello,
first of all thanks for your reply. Second, I'm totally new to this RCP-or-something-else topic but I think that I didn't forget the lib JARs. I attach the installed plugin JAR.

The thing that gets me mad is that executing this plugin once installed via "Install into host. Repository:", it does not work. At difference when executed in eclipse via Testing -> Launch an Eclipse application plugin.xml eclipse tab.

I really don't know how to take output for running plugin with -consolelog argument. I ran it with Testing -> Launch an Eclipse application, buit my only console logging was what I wrote with system.out.println.

Thanks again
Yuri

When I try to launch your Back-End command I see the following exception logged:
Caused by: java.lang.ClassNotFoundException: org.apache.commons.io.FileUtils cannot be found by it.alba.rcp.commands_1.0.0.201910241249

Which seemed odd. Looking through your jars, your embedded commons-io-2.6.jar does not look right:
$ x -d /tmp/it it.alba.rcp.commands_1.0.0.201910241249.jar 
results in /tmp/it/it.alba.rcp.commands_1.0.0.201910241249

Fantastic.
Please let me know how have you done logging the exception when launching Back-End command

and

I will check how it can be that commons-io and dom-2.3.0-jaxb-1.0.6 also contain plugin and not its own classes!

Thanks so much

Yuri

So, I have exported again with "Export wizard", but specifying directory to "C:/Users/yuri.di.carlo/eclipse-rcp/.metadata/.plugins/org.eclipse.pde.core/install/", not "Install into host" option as before.

Dimension of JAR has changed (there are real JARs mentioned before) - 200KB, but not steady execution.

ok, but when you specified this argument? in "run configuration" in eclipse? or when you executed plugin once installed?
in the 2nd case, when have you done that?

sorry for the newbie quests

thanks

I probably shouldn't execute code I haven't seen :-). Exception trace below.

I'll recommend that you explore performing your builds using Maven/Tycho. The "Export" wizards can be difficult to diagnose when there is a failure.

Specify `-consolelog` on the command-line. If you're launching from within Eclipse, in the Launch Configuration's _Program Arguments_. If you're running from the command-line: `eclipse -consolelog`. On Windows, it will open a new CMD window to show the output.
