Concept of Minimal and Full assembly

[skabashnyuk]

What does this PR do?

The main goal of this issue is to introduce two maven modules for ws-agent minimum set of components that need to start workspace agent. codenvy-ide-core is core ide part, codenvy-wsagent-core is core server side part of workspace agent.

How to use them
We will use them in two ways:

• As a fundament of our full assembly.
• As a fundament for our samples.

Full assembly of IDE
To make Full assembly of ide we need to declare in assembly/compiling-ide-war/pom.xml

1. IDE Core

        <dependency>
            <groupId>org.eclipse.che.core</groupId>
            <artifactId>che-ide-core</artifactId>
        </dependency>

2. All IDE plugins we have in Codenvy.

        <dependency>
            <groupId>com.codenvy.plugin</groupId>
            <artifactId>codenvy-plugin-*</artifactId>
        </dependency>

3. All IDE plugins we have in Che.

    <dependency>
            <groupId>org.eclipse.che</groupId>
            <artifactId>assembly-ide-war</artifactId>
            <classifier>classes</classifier>
            <exclusions>
                <exclusion>
                    <artifactId>che-plugin-product-info</artifactId>
                    <groupId>org.eclipse.che.plugin</groupId>
                </exclusion>
            </exclusions>
        </dependency>

Custom assembly of IDE based on minimal Codenvy IDE
To make Custom assembly of IDE based on minimal Codenvy IDE* we need to declare in assembly/assembly-ide-war/pom.xml

1. Codenvy IDE Core

        <dependency>
            <groupId>com.codenvy.onpremises</groupId>
            <artifactId>codenvy-ide-core</artifactId>
            <scope>provided</scope>
        </dependency>

2. IDE part of custom plugin.

        <dependency>
            <groupId>my.plugin</groupId>
            <artifactId>plugin-json-ide</artifactId>
            <scope>provided</scope>
        </dependency>

3. IDE war that will be reused to get some resources

        <dependency>
            <groupId>com.codenvy.onpremises</groupId>
            <artifactId>assembly-ide-war</artifactId>
            <type>war</type>
            <scope>runtime</scope>
        </dependency>

Full assembly of Ws-agent server war

1. Core Ws agent war

        <dependency>
            <groupId>com.codenvy.onpremises.wsagent</groupId>
            <artifactId>codenvy-wsagent-core</artifactId>
            <type>war</type>
        </dependency>

2. Swagger support

        <dependency>
            <groupId>org.eclipse.che.lib</groupId>
            <artifactId>che-swagger-module</artifactId>
        </dependency>

3.All Codenvy ws-agent plugins

        <dependency>
            <groupId>com.codenvy.plugin</groupId>
            <artifactId>codenvy-plugin-*</artifactId>
        </dependency>

4.All Che ws-agent plugins

   <dependency>
            <groupId>org.eclipse.che</groupId>
            <artifactId>assembly-wsagent-war</artifactId>
            <classifier>classes</classifier>
            <exclusions>
                <exclusion>
                    <artifactId>che-wsagent-core</artifactId>
                    <groupId>org.eclipse.che.core</groupId>
                </exclusion>
            </exclusions>
        </dependency>

Custom assembly of ws-agent base minimal Codenvy ws-agent

1. Core Ws agent war

        <dependency>
            <groupId>com.codenvy.onpremises.wsagent</groupId>
            <artifactId>codenvy-wsagent-core</artifactId>
            <type>war</type>
        </dependency>

2. Plugin server side

        <dependency>
            <groupId>my.plugin</groupId>
            <artifactId>plugin-json-server</artifactId>
        </dependency>

[benoitf]

it seems branch requires rebase updates (or it will be a squash merge ?)

@bmicklea @JamesDrummond after this pr eclipse-che/che-archetypes#44 plugin-json-archetype will be based on minimal assembly.
