webjars and wro4j-maven-plugin

[Dave Paroulek]

I noticed that the wro4j-maven-plugin can't seem to find webjars on the classpath? I have the plugin defined in my pom like so: 

<plugin>

        <groupId>ro.isdc.wro4j</groupId>

        <artifactId>wro4j-maven-plugin</artifactId>

        <executions>

          <execution>

            <phase>compile</phase>

            <goals>

              <goal>run</goal>

            </goals>

          </execution>

        </executions>

        <configuration>

          <minimize>true</minimize>

          <destinationFolder>${basedir}/src/main/webapp/static/</destinationFolder>

          <contextFolder>${basedir}/src/main/webapp/</contextFolder>

          <wroFile>${basedir}/src/main/webapp/WEB-INF/wro.xml</wroFile>

          <wroManagerFactory>ro.isdc.wro.maven.plugin.manager.factory.ConfigurableWroManagerFactory</wroManagerFactory>

          <ignoreMissingResources>false</ignoreMissingResources>

        </configuration>
       </plugin>

And then I have the jquery web jar listed as a dependency: 

    <dependency>

      <groupId>org.webjars</groupId>

      <artifactId>jquery</artifactId>

      <version>1.9.1</version>

    </dependency>

My wro.xml contains: 

<group name="jquery">
    <js>classpath:/META-INF/resources/webjars/jquery/1.9.1/jquery.js</js>
  </group>

 

At runtime, this works fine. But at build time, I see this: 

[INFO] processing group: jquery.js

0    ERROR PreProcessorExecutor - Cannot ignore missing resource:  ro.isdc.wro.model.resource.Resource@1f87f5d[JS,classpath:/META-INF/resources/webjars/jquery/1.9.1/jquery.js,true]

1    ERROR WroRuntimeException  - Exception while merging resources: Couldn't get InputStream from this resource: classpath:/META-INF/resources/webjars/jquery/1.9.1/jquery.js

My next step is to debug thru the wro4j-maven-plugin. I suspect maybe maven plugin's can't see the project's runtime dependencies? or something strange like that? I'll keep digging, but just wondered if anyone has seen this before?

Thanks!

Have you tried the following: 

classpath:META-INF/resources/webjars/jquery/1.9.1/jquery.js

Notice the missing / after "classpath:" prefix. Probably the ClasspathUriLocator can be improved to detect stream correctly also when leading / is encountered.

Cheers,

Alex

Thanks Alex, removing the first "/" fixed the issue.
