Java11中找不到jdk.incubator.httpclient模块

Question

Using the early access build for JDK/11 to compile an existing code based on Java-9 which was using a VM argument

--add-modules jdk.incubator.httpclient

to resolve the HTTP/2 client incubator module now ends up with a compilation error

Module not found: jdk.incubator.httpclient

Java version details :-

 java 11-ea 2018-09-25 Java(TM) SE Runtime Environment 18.9 (build 11-ea+11) Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11-ea+11, mixed mode) 

Answer 1

With the standardization of the HTTP Client API , the incubated APIs are now removed.

The module name and the package name of the standard API will be java.net.http which can now be used as -

module <yourModuleName> {
    requires java.net.http;
}

Also, adding to the tally, the applications, frameworks(like Maven, Gradle etc) or IDEs relying on the classpath would no more need to set the following command-line option to request the incubator module to be resolved:

--add-modules jdk.incubator.httpclient    OR      --add-modules java.net.http

Since being a standard module the java.net.http module shall be resolved by default .

Edit :- I've jotted down the migration steps required for a transition from incubation to the standard implementation of the HTTP/2 client @ Medium .
