The motivation for writing EmJar was dissatifaction with the existing approaches to distributing a Java project along with its dependencies in a single file (aka "fat jars", "über jars", "jar-in-jars" or similar). At the time, the prevailing alternatives were Maven Shade or One-JAR. This mini project showcases some of the differences between the different alternatives, and highlights some of our motivation for writing our own tool for this. This biased and unscientific, and our priorities will likely not be your priorities, so reader discretion is advised. If nothing else, this is also an example of how to integrate some of the other fat jar alternatives in a Maven flow (which is not to say that they all represent best practices).
Refer to the pom and source code for some comments about the peculiarites of the different alternatives.
Run mvn clean verify -Dmaven.profile -Pbare,emjar,shade,onejar,springboot,jarinjar to exercise packaging
and test runs of all the different alternatives; a time usage summary
will be presented at the end of the run. (Be aware that some of the
packaging executions share dependencies, which will favour the
executions being run after the dependency has already been resolved.
For accurate timing results, profile one alternative at a time.) To
run the integration tests under a non-default JRE, specify
-Djava.executable=.../bin/java to indicate a different Java runtime.
One of the challenges with multiple jars embedded in a single jar is to make sure all references to per-jar META-INF information is handled correctly -- pay attention to the jetty version string in the example runs to see what happens when this fails.
| Tool | Classpath scanning | META-INF separation | Signed embedded dependencies |
|---|---|---|---|
| Maven Shade | ✔️ | ❗ | ❗ |
| One-JAR | ❗ | ✔️ | ✔️ |
| Spring Boot | ❗ | ✔️ | ✔️ |
| Eclipse Runnable Jar | ❗ | ❗ | ✔️ |
| EmJar | ✔️ | ✔️ | ✔️ |
With large dependency sets, packaging and execution time will also tend to differ betweem the tools. The following is a rough sample of what the timings look like for this simple demo project:
| Tool | Package | Execute |
|---|---|---|
| Bare (Filesystem) | - | 1.482s |
| Maven Shade | 1.722s | 1.477s |
| One-JAR | 2.257s | 1.985s |
| Spring Boot | 0.305s | 2.375s |
| Eclipse Runnable Jar | 1.888s | 3.091s |
| EmJar | 0.143s | 1.578s |
For a quick introduction in how to use EmJar, see the emjar-maven-plugin description.
The following is an example run showing executions of the jars created by the different tools under different circumstances:
