The full error message:

Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:2.3:shade (default) on project --: Error creating shaded jar: INVOKESPECIAL/STATIC on interfaces require ASM 5 -> [Help 1]

The jarfile which I am attempting to shade is located in my own remote repository, using sonatype nexus. Here is my pom configuration:

Googling around for the error lead to very few results, the main parts of information that I gathered was that Java 8's static interface methods could cause this, however I haven't been able to find much more. The jarfile I am attempting to shade does indeed have one of these static methods, but even still surely I must be able to use them and shade the jar? I'm not sure what the error means by requiring "ASM 5" (assembly?), so any direction would be appreciated.

My effective pom (mvn help:effective-pom):

Since I recently got the same problem and it took me quite a while to fix it, here's what I did:

The required version for ASM is 5.0.3. However, the currently available version in the shade plugin is 5.0.2. Looking at the JIRA tickets, it looked like it already was fixed in 2.4, but that version is not available for the public yet (it's May the 4th of 2015 by the time I'm writing this).

So all you have to do is activate the developer versions (Based on https://maven.apache.org/guides/development/guide-testing-development-plugins.html) by adding this section to your pom:

<pluginRepositories>
    <pluginRepository>
        <id>apache.snapshots</id>
        <url>http://repository.apache.org/snapshots/</url>
    </pluginRepository>
</pluginRepositories>

and setting the plugin's version to 2.4-SNAPSHOT:

<plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>2.4-SNAPSHOT</version>
    </plugin>
</plugins>

Hope this helps!
