Create release with all dependencies

Hi, currently some of the dependencies are missing in palantir-java-format.jar. A few months ago it was working without any problem because palantir's java-format had the same dependencies as google-java-format and users who use palantir-java-format as cli used to run it with the following classpath:

/usr/bin/java  \
    -cp /usr/share/java/palantir-java-format/palantir-java-format.jar:/usr/share/java/palantir-java-format/palantir-java-format-spi.jar:/usr/share/java/google-java-format/google-java-format-all-deps.jar \
    com.palantir.javaformat.java.Main "${@}"

As you can see, we just used the dependencies provided by google-java-format-all-deps.jar.

But now palantir-java-format has some dependencies that are not packed into jar, for example, org.openjdk.* and it's actually quite impossible to use palantir-java-format as cli right now. The solution would be to pack all dependencies into a jar (either into palantir-java-format.jar or a separated one — palantir-java-format-all-deps.jar like google does).

For example this patch can be applied (I can send PR if it's a viable solution):

diff --git a/gradle/publish-jar.gradle b/gradle/publish-jar.gradle
index 1e017db..d9f99e4 100644
--- a/gradle/publish-jar.gradle
+++ b/gradle/publish-jar.gradle

     manifest {
         attributes("Implementation-Version" : project.version)
     }
+
+  from {
+    configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
+  }
 }

Start with gradle/publish-jar.gradle and inspect how the jar task assembles runtimeClasspath. Build the release artifact and verify that the dependencies needed by the CLI, including org.openjdk.* classes, are packaged in the main jar or a separate all-dependencies jar.
