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>
Hi Guys!
v2.1 is almost ready, There is only some documentation that should still be completed

Hi there.
Sorry to post it here. But I thought everyone here is using Java SDK it might have a higher chance to solve this problem.
Just tried to play with Java SDK on TNN. But it failed on first step.
I followed the steps on blow link
https://github.com/TheThingsNetwork/java-app-sdk/blob/master/data/data-mqtt/README.md.
Install the JAVA SDK, Install MVN, Download java-app-sdk.
But when I tried step 4: Build and cache the artifact:
mvn clean package install.
It fails with below error "
[ERROR] Failed to execute goal org.xolstice.maven.plugins:protobuf-maven-plugin:
0.5.0:compile (default) on project management: An error occurred while invoking
protoc.: Error while executing process. Cannot run program “C:\xxxx\Java\java-app-sdk-master\management\target\protoc-plugins\protoc-3.0.0-b
eta-3-linux-x86_64.exe”: CreateProcess error=216, This version of %1 is not comp

information to see whether you need a x86 (32-bit) or x64 (64-bit) version of th
e program, and then contact the software publisher -> [Help 1]
".
I went to the folder and did find the generated program “\java-app-sdk-master\management\target\protoc-plugins\protoc-3.0.0-b
eta-3-linux-x86_64.exe” but this program can’t be executed because of compatibility problem.
Does anyone have ideas on how to solve this problem?
Thanks.
B.R.
