This library provides support for Jersey 2.0 w/ Guice similar to the way it used to work in Jersey 1.x with the jersey-guice library. It uses Guice's own GuiceFilter (like jersey-guice) and it's somewhat different from the Guice/HK2 Bridge.
Go to search.maven.org and search for g:"com.squarespace.jersey2-guice" AND a:"jersey2-guice-impl" to find the current release version.
compile "com.squarespace.jersey2-guice:jersey2-guice-impl:${current.version}"
<dependency>

<version>${current.version}</version>
</dependency>Jersey/HK2 uses unfortunately SPIs and the Singleton pattern internally. Your code is effectively racing against the Servlet container's code and the first one to initialize HK2's ServiceLocatorGenerator inside its ServiceLocatorFactory wins.
This library uses two approaches to override HK2's own ServiceLocatorGenerator. It first tries to use a SPI and if it can't it'll fall back to reflection to replace a private static field. Regardless of the approach it's still a race against the Servlet container.
public static void main(String[] args) {
List<Module> modules = new ArrayList<>();
modules.add(new JerseyGuiceModule("__HK2_Generated_0"));
modules.add(new ServletModule());
modules.add(new AbstractModule() {
@Override
protected void configure() {
// ...
}
});
Injector injector = Guice.createInjector(modules);
JerseyGuiceUtils.install(injector);
// ... continue ...
