Am I using che-install-plugin correctly? I can't make the JSON plugin works

[mariosotil]

I could build the 4.7.0 version. But when I tried to configure the JSON plugin sample, I can't see it in the workspace.

I checked out the repo, build it, copy the JSON plugin Jar files to the plugins folder, and run che-install-plugin. Am I missing something?

These were the steps I took:

$ cd ~/eclipse-che
$ git checkout tags/4.7.0
[...]
$ cd che
$ mvn clean install 
[...]
$ cd assembly/assembly-main/target/eclipse-che-4.7.0/eclipse-che-4.7.0/
$ cp ~/eclipse-che/che/samples/sample-plugin-json/che-sample-plugin-json-server/target/che-sample-plugin-json-server-4.7.0.jar  ./plugins/ws-agent
$ cp ~/eclipse-che/che/samples/sample-plugin-json/che-sample-plugin-json-ide/target/che-sample-plugin-json-ide-4.7.0.jar  ./plugins/ide
$ bin/che-install-plugin.sh -a

Good Job! Your build has completed.

You can start this Che assemby to see your plugins.

So far, so good.

First attempt:

$ cd ~/eclipse-che/che/assembly/assembly-main/target/eclipse-che-4.7.0/eclipse-che-4.7.0/
$ bin/che.sh

Second attempt:

$ cd ~/eclipse-che/che/assembly/assembly-main/target/eclipse-che-4.7.0/eclipse-che-4.7.0/sdk/assembly-main/target/eclipse-che-4.7.0/eclipse-che-4.7.0
$ bin/che.sh

In both cases, Eclipse Che worked fine, but the features from the JSON plugin were not visible. There's no a 'JSON test' project, menus, etc.

My computer's configuration is

• Ubuntu 16.04.1
• Oracle Java 1.8.0_101
• Docker 1.12.1
• docker-machine 0.7.0 a650a40
• Maven 3.3.9
• Bower 1.7.9
• Gulp CLI version - 1.2.2
• I added the gwt-dev dependency, and removed all provided scopes on assembly-ide-war/pom.xml

@mariosotil Have you tried to configure JSON plugin manually? You can do that as follows:

1. Build Che.
2. Add dependencies to the ~/che/assembly/assembly-ide-war/pom.xml:

<dependency>
            <groupId>org.eclipse.che.sample</groupId>
            <artifactId>che-sample-plugin-json-ide</artifactId>
</dependency>

1. Add GWT module dependency to the ~/che/assembly/assembly-ide-war/src/main/resources/org/eclipse/che/ide/IDE.gwt.xml:

<inherits name="org.eclipse.che.plugin.jsonexample.JSONExample"/>

1. Add dependencies to the ~/che/assembly/assembly-wsagent-war/pom.xml:

<dependency>
        <groupId>org.eclipse.che.sample</groupId>
            <artifactId>che-sample-plugin-json-server</artifactId>
</dependency>

1. sortpom:sort and rebuild Che.
2. Start Che.

It seems like it worked. Thank you.

"1. Build Che."
Sorry, but for what we need build Che. We will it later how you make "rebuild Che"

[mariosotil]

@friendRU Hi. You need to read this ==> https://eclipse-che.readme.io

If you read "SETUP" and "SETUP - ALTERNATIVES", you will be able to do it.

Why do we need first to build che before we add the dependencies?
