I've spent hours trying to release a project to github with Maven. This is usually not a problem but for some reason it is for this project and I don't understand why. I'm using Maven 3.8.5 with Java 1.8.0_312 and git 2.36.1. Here's the pom.xml file:

I can push (and pull) just fine from the command line by using the git command. I've tried different versions of the maven-release-plugin to no avail. I've even deleted the entire GitHub repository and pushed it again from my local machine but still, I get the same error. What could be causing this?
A mvn -X prepare should show you which commit is checked out from your git:ssh://git#github.com/mycompany/myproject.git
Compare it with the latest commit on GitHub to understand the difference.
Trying to use an exec goal to do a git pull before mvn release is possible, but it is better to identify first why there is a remote commit that you do not have locally.

I have a project in Java + Maven. I can compile and run the code with IntelliJ just fine: each modification I do in the code gets compiled in the program. However, when I try compiling from the command line (using mvn compile), Maven doesn't recognize the changes in the code, and simply says "Nothing to compile - all classes are up to date". I can force rebuilding using mvn clean, but that invalidates the purpose of having a build system. Why is it so, and how can it detect changes in the code?
For example, say I have a working code.
I do mvn compile. It works fine and I can run the program.
I change the code and introduce a syntax error. I save the file and do mvn compile. The output is Nothing to compile, together with a BUILD SUCCESS. However, when I try to run the program, I get a Exception in thread "main" java.lang.Error: Unresolved compilation problems, along with a series of error (due to the erroneous parsing)
If I change the code to a different code, but syntactically valid, I get the same behavior.
In fact, after this, even returning to my original code compiles, but then throws a java.lang.Error exception!
Why does it work like this, and why does it work in IntelliJ, but not in terminal?
EDIT:
IntelliJ is not open. However, Emacs does start the language server (jdtls).

I tried to use Maven to install the dependency Unirest. I downloaded the .jar file (unirest-java-1.4.9.jar) and added it to the POM like this:
<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.mashape.unirest</groupId>
<artifactId>unirest-java</artifactId>
<version>1.4.9</version>
</dependency>
</dependencies>
</dependencyManagement>
In addition, I added the .jar in Eclipse:
Now Maven says that the package does not exist. Eclipse did not say that anything was wrong.
What did I do wrong?
Are the warnings in the beginning a problem?

This is how I import Unirest:
import com.mashape.unirest.http.*;
You added your dependency to the dependencyManagement section of your pom. This section is intended for multi-module projects where a dependency can be defined in the parent pom but used in child modules. Further reading.
To be able to use your dependency, you must open your child-module's pom (in this case the pom of application, unit-tests or integration-tests) and tell maven that you wish to use the dependency there like so:
<?xml version='1.0' encoding='utf-8'?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
...
<groupId>com.sap.cloud.sdk.sensorLive</groupId>
<artifactId>application</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>jar</packaging>
<dependencies>
<dependency>
<groupId>com.mashape.unirest</groupId>
<artifactId>unirest-java</artifactId>
</dependency>
</dependencies>
...
</project>
Try removing unirest-java dependency from dependencyManagement tag and add in dependencies tag like below example
Sample example:
<dependencies>
<dependency>
<groupId>com.mashape.unirest</groupId>
<artifactId>unirest-java</artifactId>
<version>1.4.9</version>
</dependency>
</dependencies>
if your using Eclipse, just do a maven update and that should do the trick.

Thanks a lot
I am an automation qa engineer and I've been charged with setting up our Jenkins CI framework. The issue that I am having is that Maven is failing in the build phase. In looking at the log there a few things that are concerning to me but I am not sure if they are related or relevant. See the log below

It seems as though when I attempt to run the mvn commands it tries to reference srs folders that don't exist (not sure if this does any harm) it doesn't recognize my TestnNG profile specified in my POM file (I am assuming this will impact Jenkins) and there is some property/configuration error in my pom file (Per the ERROR message in my log) that I cannot resolve.

I found out the issue:
In the example
https://github.com/apache/spark/blob/master/examples/src/main/java/org/apache/spark/examples/sql/JavaSparkSQL.java
replace the line schemaPeople.registerTempTable("people");
with schemaPeople.registerAsTable("people");
compile and package with mvn compile and mvn package and run with
bin/spark-submit --class "org.apache.spark.examples.sql.SimpleApp" --master local[4] try/simple-project/target/simple-project-1.0.jar
