cassandra datastax Unexpected error while writing generated code: java.lang.NullPointerException

I have a java class
import com.datastax.oss.driver.api.mapper.annotations.Dao;
import com.datastax.oss.driver.api.mapper.annotations.Delete;
import com.datastax.oss.driver.api.mapper.annotations.Insert;
import com.datastax.oss.driver.api.mapper.annotations.Select;
#Dao
public interface ProductDao {
#Select
Product findById(UUID productId);
#Insert
void save(Product product);
#Delete
void delete(Product product);
}
For which I would like to use for cassandra record fetching.
I was trying the doc - https://github.com/datastax/java-driver/tree/4.x/manual/mapper
when I try building it with maven I get an NPE

This line in the stack trace and upwards starting from -
[ERROR] at com.datastax.oss.driver.internal.mapper.processor.entity.DefaultEntityFactory.getDefinition(DefaultEntityFactory.java:80)
Indicated to me that it was an issue on the entity class, not the Dao itself. With that in mind, I could replicate this stack trace by removing the #Entity annotation on the class that the Dao was to return, in your case that would be Product.
My expectation is that the Product class is not annotated correctly, we would need the code added from that class to further diagnose / confirm.

Unresolved Reference when use Java Constants

When i tried to build, ide throw error: "Unresolved reference: X "
X is any Java constant (public static final) on (public) class Java
Can’t use:
android.os.Environment.DIRECTORY_DOCUMENTS
Build.VERSION_CODES.M
Etc
I have tried:
Invalidate Cache in Android Studio
gradlew cleanBuildCache
Clean / Rebuild
Clone project on other folder,
Etc
It’s a mixed project, Java & Kotlin
I can use static methods, like:
public static Uri getUriForFile from public class FileProvider
Etc

Thank you #yole and #Rod_Algonquin for the help, meanwhile i was writing the questions, and answering the questions, the Rubber duck method help me, the IDE was throwing me a error "Unresolved reference", but the problem was the annotation:
#RequiresApi(Build.VERSION_CODES.M)
Because: minSdkVersion 16
I was working on PermissionsHelper.kt, I was using Activity instead of android.support.v4.app.Fragment or ContextCompat for old versions.
Sorry guys for not post the code, and the complete gradle, i wanted to do a short post, this is my fist post.
Thank yo for all the help.

I believe you just missed a '}' in build.gradle file. Should be quite straightforward to fix.

Missed "}" in the code

Update class path to
classpath 'me.tatarka:gradle-retrolambda:3.2.5'
then add this to your dependencies
retrolambdaConfig 'net.orfjackal.retrolambda:retrolambda:2.3.0'
Add following code to application block
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
After this it should work.
Update:
The latest version of retrolambda till today (September 11 2017) is 3.7.0

Add this in app gradle build file before android block (on top)
//noinspection GradleCompatible
apply plugin: 'com.android.application'
apply plugin: 'me.tatarka.retrolambda'
tasks.whenTaskAdded { task ->
if (task.name.startsWith("lint")) {
task.enabled = false
}
}
retrolambda {
jvmArgs '-noverify'
}
and I also changed my class path version from 3.4.0 to 3.2.5 and my issue resolved.
Also no need to add retroLambdaConfig

When I updated the AS project to AS 3.4.1, there were a lot of problems, and I finally got stuck on this error message. There was very little related information on the Internet, let alone the solution. In desperation, I looked at other warnings. The following warning was changed casually:
One of the plugins you are using supports Java 8 language features. To try the support built into the Android plugin, remove the following from your build.gradle
The solution is to remove the previously dependent lambda library, because after version 3.0, AS itself supports lambda
apply plugin: 'me.tatarka.retrolambda' //remove this line
dependencies {
classpath 'com.android.tools.build:gradle:3.4.1'
classpath 'me.tatarka:gradle-retrolambda:3.2.4' //remote this line
}
After removing this sentence, synchronize it, and miraculously compiled successfully. It seems that this plug-in library does not exist after version 3.0, and it cannot be recognized.

gradle compile success, but fail to run project

PROBLEM
After I try to find out what is root cause of problem. why I can build successfully but unable to run project. It's because one jar file call 'signalr-client-sdk.jar' if I put in libs folder and run the following error message generated. please help me to identify it. I don't know what to do now.

Error:Could not execute build using Gradle installation '/Users/X-tivity/.gradle/wrapper/dists/gradle-2.2.1-all/c64ydeuardnfqctvr1gm30w53/gradle-2.2.1'.

Your real error is
Caused by: com.android.dx.cf.iface.ParseException: bad class file magic (cafebabe) or version (0034.0000)
This happens because your signalr-client-sdk.jar was compiled with Java 1.8:
javap -verbose -classpath signalr-client-sdk.jar microsoft.aspnet.signalr.client.transport.HttpClientTransport | grep version
minor version: 0
major version: 52
52 is Java 1.8.
You should rebuild SignalR client with Java 1.7 (javap should return major version: 51).

Download the latest version of gradle
Or you can use
classpath 'com.android.tools.build:gradle:1.2.3'
Then Rebuild and File --> Invalidate caches/restart
For more information you can read this SO Answer
Error: Gradle: execution failed for task ':app:preDexDebug'
