Re: Maven/GWT: include sources in jar with relative path?

Hello,

when making java libraries containing GWT code, you have to include the sources in the jar file.

I do this in my maven project like this:

<build>

  <resources>

    <resource>

      <directory>src/main/resources</directory>

    </resource>

    <resource>

      <directory>src/main/java</directory>

      <includes>

        <include>**/*.java</include>

        <include>**/*.gwt.xml</include>

      </includes>

    </resource>

  </resources>

</build>

This includes everything under src/main/java.

And everything that we include is relative to this path.

In my case, this is for example:

serverstuff/Database.java

serverstuff/Files.java

clientstuff/MyDialog.java

clientstuff/MyWindow.java

Now I would like to include only a subdirectory, say src/main/java/clientstuff.

To achieve this, I could change the directory tag above into

<directory>src/main/java/clientstuff</directory>

But then, also the origin of the paths in the resulting jar file changes.
The jar file will contain:

MyDialog.java

MyWindow.java

These are the classes that I want, but with a wrong path.

I want my jar file to contain:

clientstuff/MyDialog.java

clientstuff/MyWindow.java 

How can I do that?

Don't change your <directory>, play with the <includes> instead:

     <resource>

      <directory>src/main/java</directory>

      <includes>

        <include>clientstuff/**/*.java</include>

        <include>clientstuff/**/*.gwt.xml</include>

      </includes>

    </resource>

Technically, you could instead add targetPath to relocate the files, but the former above feels cleaner IMO:

    <resource>

      <directory>src/main/java/clientstuff</directory>

      <targetPath>clientstuff</targetPath>

      <includes>

        <include>**/*.java</include>

        <include>**/*.gwt.xml</include>

      </includes>

    </resource>
