How to build and run okhttp 3.10.0

Question

I clone the code from https://github.com/square/okhttp

And I want to read the source code of 3.10.0 version.

But it could not compile successfully.

gongzelong:okhttp gongzelong$ git branch
  master
* parent-3.10.0

gongzelong:okhttp gongzelong$ mvn clean verify

After adding the code which is in my answer, it could run 'mvn clean verify'

But IDEA shows error like this:

@ViralPatel thanks, before adding the jar locally, I would prefer to find out why it could not find the jar. https://mvnrepository.com/artifact/org.mortbay.jetty.alpn/alpn-boot, it has 7.1.2.v20141202 alpn. But IDEA shows error. — Francis Bacon, Dec 30 '19 at 10:07
@ViralPatel Regarding to the IDEA error, plz check the screenshot. I mean the error is shown in IDEA. 'mvn clean verify' works fine now after I did what I said in my answer. — Francis Bacon, Jan 02 '20 at 06:15
@ViralPatel Where do you find gradle? it is maven, not gradle. — Francis Bacon, Jan 07 '20 at 09:05

You can also add that library to a demo project, the in android studio changes it to Project folder. you can find it in the external libraries.

or you can download it, then use the VsCode editor to open it and read.

It is an option, but why the problem occurs and how to fix it directly? – Francis Bacon Dec 30 '19 at 08:08

you can try isaaaaame answer. but the OkHttp is a pure library if you use the android studio open it, you have to use import module or add library method. – Lenoarod Dec 30 '19 at 08:27

for org.mortbay.jetty.alpn:alpn-boot:jar must be a valid version but is '${alpn.jdk8.version}'

in their build.gradle they have

def alpnBootVersion() {
def version = System.getProperty('alpn.boot.version')

if (version != null) {
  return version
}

They have probably added alpn.jdk8.version as a variable in their local gradle.properties. Change def version = System.getProperty('alpn.boot.version') with def version = 8.1.13 , and this should solve the problem.

The codes you mentions belongs to the version 3.10.0? It seems that there are no such codes in 3.10.0 – Francis Bacon Dec 30 '19 at 09:33
@FrancisBacon check their build.gradle, it was edited 8 days ago: https://github.com/square/okhttp/blob/master/build.gradle – isaaaaame Dec 30 '19 at 09:36
What you mean is trying to build the latest source code of okhttp. But how to build 3.10.0 source codes? – Francis Bacon Dec 30 '19 at 09:38
as @Lenoarod said: "OkHttp is a pure library if you use the android studio open it, you have to use import module or add library method.". it's not meant to be build as a standalone project. – isaaaaame Dec 30 '19 at 09:44
I opened in via IDEA, so I should compile the project using maven. And the CONTRIBUTE.MD said, it could run 'mvn clean verify' successfully. – Francis Bacon Dec 30 '19 at 09:56

It is due to lack of alpn version regarding to my java version

gongzelong:okhttp gongzelong$ java -version java version "1.8.0_172" Java(TM) SE Runtime Environment (build 1.8.0_172-b11) Java HotSpot(TM) 64-Bit Server VM (build 25.172-b11, mixed mode)

So after I add the following codes in the file /Users/gongzelong/Android/okhttp/pom.xml

gongzelong:okhttp gongzelong$ git diff
diff --git a/pom.xml b/pom.xml
index 8b87c2038..274159c3e 100644

 </project>

It could run 'mvn clean verify' and 'mvn clean install'.
