previous version (http://search.maven.org/#artifactdetails|org.thethingsnetwork|java-app-lib|1.0.0|bundle) should still work! It just lacks new features but it’s fine for standard uplink & downlink via mqtt
Oh, thank u very much!!! I will check it out, if you will need any help with contributing this java sdk maybe i will be able to help 
All unassigned issues (https://github.com/TheThingsNetwork/java-app-sdk/issues) are waiting for somebody to take care of them 
Actually i have still the same problem, my IDE - intelij idea cannot resolve this dependancy. I’m still getting the error that dependancy is not found. Is there any thing that i have change in my IDE settings, i mean for example add some magical maven repsitory which is nescessary to use this dependancy?
Or maybe there is some REST api which i will be able to use, to recive data from my TTN application?
v1 was working fine and it was used by quite a few people.
Can you make sure you used this:
<dependency>
<groupId>org.thethingsnetwork</groupId>
<artifactId>java-app-lib</artifactId>
<version>1.0.0</version>
</dependency>
If you’re still having errors, ping me on slack
There is interesting thing, when i run intelij idea on mac there was a problem with resolving dependancy but when i try on windows it works fine
Probably the solution is that on mac i have the newer version of intelij idea then on windows
Interesting. If you manage to have more information about why it’s not working on your mac, please share it… This could probably help others (I don’t have a mac, nor windows 
)
So you say that you are using the best OS called linux? 
Last time I saw a post like that was followed by a linux-hater/linux-lover war
haha
Btw. do you have any documentation for this 1.0.0 version?
API is very close. Here is a link to the quick start of the v1.x branch: https://github.com/TheThingsNetwork/docs/tree/2d4bc74521f711b2e7ebc7577000abcd303c0fa0/_includes/v2-preview/java

Cambierr,
i’m trying to do the quick start as is written in given tutorial but i have problem.
Do you have any idea what is wrong?
Well, this seems to be due to the fact that you use a mix of v2 and v1!
in v1, you should not use a ConnectHandler as done in v2: you should use a Consumer, as suggested by your IDE.
Check the provided sample at https://github.com/TheThingsNetwork/java-app-sdk/tree/230d9df5c3a9491f8f2fa8703e3bcbfef7ac8810/sample
Thank you very much,
Oh, thats right, that was bad mix Do you know anything about some hello-world application ttn, to test sdk options?
I mean, is there any open application to test (which is reciving some frames from nodes etc)?
afaik, no, but this could be an interesting thing to setup!
Meanwhile, @Rafal, I’ll DM you some credentials used in an app having ~ 25 sensors transmitting every 10 minutes
@cambierr i still didnt receive your message 
did you sent it?
Thank you very much for your help and sory for being impudence
Hello,
I have a similar problem. I tried to follow the quick start instructions to install the Java SDK. After creating the Java project I added the given dependency into the created pom.xml and tried to compile everything.
But the build failed due to the following Error:
[ERROR] Failed to execute goal on project mqtt: Could not resolve dependencies for project org.thethingsnetwork.samples.mqtt:mqtt:jar:1.0-SNAPSHOT: Failed to collect dependencies at org.thethingsnetwork:data-mqtt:jar:2.0.0: Failed to read artifact descriptor for org.thethingsnetwork:data-mqtt:jar:2.0.0: Failure to find org.thethingsnetwork:app-sdk:pom:2.0.0 in https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1]
Do you have an idea how to fix this or which step I missed?
I had the same problem as you. There is some problem with 2.0.0 version and now you should use the latest stable version which is 1.0.0.
I was talking with the most active guy which is doing this lib and he told me that he is working on fix those bugs which are make unable to use 2.0.0 vesrsion
Protip try to not mix these two versions because it will not works
Try this version, in my project works correct.
<dependency> <groupId>org.thethingsnetwork</groupId> <artifactId>java-app-lib</artifactId> <version>1.0.0</version> </dependency>
