Description

We've switched from 3.6.0 to 3.7.0, and our assemblies are now failing with:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:3.7.0:single (assemblies) on project my-project: Execution assemblies of goal org.apache.maven.plugins:maven-assembly-plugin:3.7.0:single failed: Cannot invoke "java.io.File.isFile()" because "this.inputFile" is null -> [Help 1]

Our configuration looks like this:

<plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <executions>
                    <execution>
                        <id>assemblies</id>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                        <configuration>
                            <formats>
                                <format>zip</format>
                            </formats>
                            <descriptors>
                                <descriptor>src/main/assembly/component.xml</descriptor>
                            </descriptors>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

And our descriptor looks like this:

<assembly xmlns="http://maven.apache.org/ASSEMBLY/2.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/ASSEMBLY/2.0.0 http://maven.apache.org/xsd/assembly-2.0.0.xsd">

    <id>component</id>
    <includeBaseDirectory>false</includeBaseDirectory>

    <fileSets>
        <fileSet>
            <directory>${resources.dir}/config</directory>
            <outputDirectory>.</outputDirectory>
        </fileSet>
    </fileSets>
</assembly>

Our resources folder just contains a few text files.

I assume it's related to changes brought in on MASSEMBLY-1013
