liferay-mobile-sdk-builder NullPointerException

[Genar Codina，修改在7 年前。]

I am using:
liferay-mobile-sdk-builder-6.2.0.17
in order to get the custom services deployed in a Liferay 6.2 CE Server.

That server has the following public address:

http://212.36.85.172/api/jsonws

in the previous address it is possible to see that the "Context Path" contains several portlets, and the one develped by us is called "Servicio-mobile-portlet"; so, I try to create the custom SDK for the methods published by that custom portlet ("Servicio-mobile-portlet").

To create the SDK for iOS I have executed:
./gradlew createModule -P=all --debug --info
and then I have introduced the following information:

Context:Servicio-mobile-portlet
Platforms:ios
Server:http://212.36.85.172:80
Filter:
Portal Version:62
Module Version:1.0

And then I have got the following error:

So, paying attention on:

Exception in thread "main" java.lang.NullPointerException
	at com.liferay.mobile.sdk.SDKBuilder.main(SDKBuilder.java:46)

I have gone to the source code of "SDKBuilder.java", at line 46; that is:

public class SDKBuilder {

        public static void main(String[] args) throws IOException {
                SDKBuilder builder = new SDKBuilder();

                Map<string, string> arguments = builder.parseArguments(args);

                String[] platforms = arguments.get("platforms").split(",");
                String url = arguments.get("url");
                String context = arguments.get("context");  //This is line 46
                String packageName = arguments.get("packageName");
                String filter = arguments.get("filter");
                int portalVersion = Integer.valueOf(arguments.get("portalVersion"));
                String destination = arguments.get("destination");

                try {
                        builder.build(
                                platforms, url, context, packageName, filter, portalVersion,
                                destination);
                }
                catch (Exception e) {
                        _log.log(Level.SEVERE, e.getMessage(), e);
                }
        }
...</string,>

Line 46 corresponds to:

String context = arguments.get("context");

So, it seems that there is an error trying to get the context (which in my case is "Servicio-mobile-portlet").

I do not know the cause of that error; perhaps the problem is in the way the corresponding .jar/.war files of "Servicio-mobile-portlet" have been generated (however, all the custom services can be seen in a browser in the following url: http://212.36.85.172/api/jsonws)

Any suggestion will be welcomed.

Thanks in advance,

Can you try with the previous release? it's the tag builder-6.2.0.16

It seems to be a bug with the 7.0 support.

[Genar Codina，修改在7 年前。]

Hi,

Thanks for your answer; however I have tried also the version builder-6.2.0.16, but I could not generate the custom mobile SDK (I tried also to use the last version "builder-7.0.0", but without a successful result).

I could try to create a project related to this project and then to debug it.

Thanks,

Hi, it looks like the problem is in the sdk-builder dependencies loading, look at the "sdk-boulder.gradle" file, from line 5 to line 10,

dependencies {
	if (project.parent && (project.parent.name == 'liferay-mobile-sdk')) {
		builder project(':builder')
	}
	else {
		builder group: 'com.liferay.mobile', name: 'liferay-sdk-builder', version: '6.2.0.+'
	}
}

Remote dependency is loaded: (version: '6.2.0.+') as checking for a local 'builder' project validation fails , it seems that the remote version loaded is wrong, a quick fix is to remove the validation and load local builder project:

dependencies {
		builder project(':builder')
}

Hi Mauricio,

Thanks for your suggestion. You are right, using the changes proposed by you I could finally generate the corresponding files (.zip for iOS and .jar for Android).

[Egor Merkushev，修改在7 年前。]

Why is this fix not in git? I spent a lot of time to build SDK...

Hi Egor, it is in GitHub:
