Maven Eclipse multi-module shaded dependency

问题

In a multi-module Maven project, one of the modules is a shaded module (e.g. no source, but generates a jar during package phase). Other modules reference this module as a dependency (all under same parent). Is there a way to have Eclipse recognize the shaded module as a dependency? Eclipse only covers up to compile.

Currently it works on the command line (since package is run), but in Eclipse it shows errors.

I have not been able to find a solution to this.

Details:

- Parent project
   - Module A
   - Module B

Module A is a shaded module meaning it has something like:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <executions>
                <execution>
                    <id>shade</id>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                    <configuration>
                        <relocations>
                            <relocation>
                                <pattern>com.third.party</pattern>
                                <shadedPattern>my.shaded.third.party</shadedPattern>
                            </relocation>
                        </relocations>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

Module B has Module A as a dependency (under dependencies-dependency). Module B tries to use classes from Module A by importing the relocated paths ...e.g:

import my.shaded.third.party.Foo;

This doesn't work because it can't find Foo. This makes sense since only compile phase is run in Eclipse build.

回答1:

Rightclick on dependent project > Maven > Disable Workspace Resolution

This will tell Eclipse to use Maven's compilation instead, meaning you will be able to use my.shaded.* imports.

However, this does have the consequence that your projects will not be updated until you build them using maven. It is a solution to get Eclipse to recognise shaded dependencies, nevertheless.
