No source code is available for type <type> did you forget to inherit a required module?

问题

I am trying to split my project into 4 Java modules:

web-client
web-client-admin
web-client-landing
web-client-core

The module web-client is the one that puts all pieces together, so the dependency tree would look something like this:

                <-- web-client-admin <----
               /                          \ 
web-client <---                            <---- web-client-core
               \                          /
                <-- web-client-landing <--

In my module.gwt.xml I am having:

<inherits name="com.mz.client.application.landing" />
<inherits name="com.mz.client.application.admin" />
<inherits name="com.mz.client.application.core" />

and the java modules are in the pom.xml of the web-client module:

    <dependency>
        <groupId>com.mz</groupId>
        <artifactId>mz-web-client-admintool</artifactId>
        <version>0.1-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>com.mz</groupId>
        <artifactId>mz-web-client-landing</artifactId>
        <version>0.1-SNAPSHOT</version>
    </dependency>

However, I am getting:

I don't see what I am missing here..

回答1:

You either need to include source files as resources into your modules, or add dependencies to the sources artifacts in addition to the jar ones.

Given that these are all client modules, I'd rather include the sources into the JARs.

You can simply declare src/main/java as an additional <resource>, or you can use a gwt-maven-plugin (maybe have a look at https://tbroyer.github.io/gwt-maven-plugin/ gwt-lib packaging; disclaimer: I'm the author)
