Description

Configuration as follows:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <configuration>
        <createSourcesJar>true</createSourcesJar>
    </configuration>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>shade</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Dependency defined as follows:

<dependency>
  <groupId>javax.jnlp</groupId>
  <artifactId>jnlp-api</artifactId>
  <version>1.7.0_06</version>
</dependency>

Sources for javax.jnlp for some reason disappeared from our maven repo proxy, which made maven-shade-plugin to output:

[INFO] Including javax.jnlp:jnlp-api:jar:1.7.0_06 in the shaded jar.
[WARNING] Could not get sources for javax.jnlp:jnlp-api:jar:1.7.0_06:compile

and in turn:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:3.0.0:shade (default) on project xxxxx: Execution default of goal org.apache.maven.plugins:maven-shade-plugin:3.0.0:shade failed. NullPointerException -> [Help 1]
