lti-example-java was out-of-date, and using an old branch of basiclti-util-java (one where the package structure wasn't compatible with 1.0.0 or 1.0.1).
It's updated and should be working now.

Use
<dependency>
<groupId>org.imsglobal</groupId>
<artifactId>basiclti-util</artifactId>
<version>1.0.0</version>
</dependency>
version 1.0.0 contains the basiclti package.Version 1.1.1 removes the basiclti package

Update:
From the snapshot, it looks like your JRE System library is set to Java SE 1.7 where as the JARs are of version 1.8.0_251. In POM, change the Source and Target versions to 1.8. Also please remove the installed JRE and change that to JDK 1.8.0_251. Do a project clean and rebuild after that.
Click remove and then add library.
Choose the JDK 1.8 which you have
Also check the compiler level:
Probably you are missing some dependencies (as the log says some packages not found)
Do you have these dependencies in your pom.xml?

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project grpc_hello_server: Compilation failure

I'm trying to create a gRPC service with Java using below codelab.
I created a sample proto file. While compiling the .proto using maven, i got a build failure error. It says javax.annotation.Generated anottation class is not found.
Could you help me find the root cause of the issue and steps to fix it. I feel it should be a versioning issue but not clear on how to solve it.

Issue is due to missing dependency in pom.xml for Java 9+
<dependency> <!-- necessary for Java 9+ -->
<groupId>org.apache.tomcat</groupId>

Any reason you are using Java 1.6?
<maven.compiler.source>1.6</maven.compiler.source>
<maven.compiler.target>1.6</maven.compiler.target>
Can you change it to 1.7 and see if it works?

First of all remove the unwanted testng dependency from the POM.xml and second you have added the scope as test in the testng dependency. You have also accessed the class file of the testng dependency with the scope test in src/main/java. Please remove the test scope from the dependency and then execute the test again. Let me know if the issue persists even after fixing the above issues.

This was not happening when running the mvn compile command before, but after updating my POM and re-compiling, it started to show in the terminal too. The project works perfectly fine when running it from the testng.xml in eclipse.

I was finally able to solve this by updating my POM file doing the following:
Removing the extent report dependency that had the avenstack groupID
<dependency>
<groupId>com.aventstack</groupId>
<artifactId>extentreports</artifactId>
<version>3.0.6</version>
</dependency>
updating the other Extent Report to this v:
<dependency>
<groupId>com.aventstack</groupId>
<artifactId>extentreports</artifactId>
<version>3.1.5</version>
</dependency>
And adding this one too:
<dependency>
<groupId>org.freemarker</groupId>
<artifactId>freemarker</artifactId>
<version>2.3.28</version>
</dependency>

Maven can't find classes after downloading dependencies

I am new to Maven and I am trying to write a small piece of Java code. I am including some packages. Maven seems to download everything I am expected to need but when it comes to compiling it fails saying it can't find a particular class. The errors further state that it can't find any of of my imports. Can someone tell me what I am missing?
This is my code:
package in.myscratchpad.app;
import com.amazonaws.AmazonClientException;
import com.amazonaws.AmazonServiceException;
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.profile.ProfileCredentialsProvider;
import com.amazonaws.regions.Region;
import com.amazonaws.regions.Regions;
import com.amazonaws.services.dynamodb.AmazonDynamoDBClient;
/**
* Hello world!
*
*/
public class App
{
public static void main( String[] args )
{
System.out.println( "Hello World!" );
AmazonDynamoDBClientBuilder builder = AmazonDBClientBuilder.standard();
}
}
This is my pom.xml:

When I simple keep the Hello, World code without the AWS packages it works fine, when I try to build the service client I get these errors.

It says
...cannot find symbol
[ERROR] symbol: variable AmazonDBClientBuilder
[ERROR] location: class in.myscratchpad.app.App
Which seams to explain clearly that it can compile in.myscratchpad.app.App because there is a symbol in it (namely AmazonDBClientBuilder) which can not be found!
I don't know what this class is for but given that
you do not have import for AmazonDBClientBuilder class
you assign the result to AmazonDynamoDBClientBuilder type
isn't that a typo in your code and you should use AmazonDynamoDBClientBuilder.standard() instead?

maven can't find dependency basiclti-util - java

lti-example-java was out-of-date, and using an old branch of basiclti-util-java (one where the package structure wasn't compatible with 1.0.0 or 1.0.1). It's updated and should be working now.

Use <dependency> <groupId>org.imsglobal</groupId> <artifactId>basiclti-util</artifactId> <version>1.0.0</version> </dependency> version 1.0.0 contains the basiclti package.Version 1.1.1 removes the basiclti package
