I am trying to follow the tutorial in Chapter 7 in this online book: http://books.sonatype.com/mvnex-book/reference/index.html
This tutorial is intended to demonstrate a web application with Spring Framework with hibernate, and I am stuck hereļ¼

Try adding version for your plugin for maven-jetty-plugin and see if that fixes the issue, as there is a warning that says:
[WARNING] 'build.plugins.plugin.version' for org.mortbay.jetty:maven-jetty-plugin is missing. # org.sonatype.mavenbook.multispring:simple-webapp:[unknown-version], /home/abigail/workspace/simple-parent/simple-webapp/pom.xml, line 46, column 21

For example:
<version>4.2.14</version>
can you try with the below plugin.
<plugin>
<!-- Run "mvn hibernate3:hbm2ddl" to generate schema -->
<groupId>org.codehaus.mojo</groupId>
<artifactId>hibernate3-maven-plugin</artifactId>
<version>${hibernate3.maven.plugin.version}</version>
<configuration>
<hibernatetool>
<annotationconfiguration propertyfile="src/main/resources/${hibernate.properties}" />
<hbm2ddl update="true" create="true" export="false"
outputfilename="${hibernate.hbm2ddl.sqlfile}" format="true"
console="true" />
</hibernatetool>
</configuration>
</plugin>
instead of
<groupId>org.codehaus.mojo</groupId>
<artifactId>hibernate3-maven-plugin</artifactId>
<version>2.0</version>
<configuration>
<components>
<component>
<name>hbm2ddl</name>
<implementation>annotationconfiguration</implementation>
</component>
</components>
</configuration>
I had the same problem as you (using Java 8) and solved it by switching the version of the plugin to 2.2 from 2.0. If you try out newer version it appears to break again.
Wonder if there is a better way to solve such version issues than trial and error combined with extensive search engine usage.

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>

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?

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>

<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.
I have created a test for my aspectj class.
When I execute my test it works fine to "Run as TestNG" from Eclipse.
Then when I execute it in maven:
mvn clean test
I get the following error:

What am I missing here?
Why is the aspectj not compiled before the test case?
Is there a way to change this?
I used this example ( for the library part) to follow since I am creating a lib that should be used for other applications:
AspectJ: How to weave an aspect library into a Java project
TestClass:
/**
* Unit test to see if pointcut works as expected in ${#link DeprecatedMethodsAspect}
*/
public class DeprecatedMethodsAspectTest {
private DeprecatedMethodsAspect aspect;
private DeprecatedMethods deprecatedMethodsMock;
private DeprecatedMethodsApp app;
#BeforeClass
public void setUp() throws Exception {
app = new DeprecatedMethodsApp();
deprecatedMethodsMock = mock(DeprecatedMethods.class);
when(deprecatedMethodsMock.isActive()).thenReturn(true);
aspect = Aspects.aspectOf(DeprecatedMethodsAspect.class);
aspect.setDeprecatedMethods(deprecatedMethodsMock);
}
#Test
public void testSumIsMatched() throws Throwable {
app.sum(1, 2);
verify(deprecatedMethodsMock, times(1)).collect(any(JoinPoint.class));
}
#Test(description = " we should not gather information from methods annotated #Beta.")
public void testSubIsNotMatched() throws Throwable {
app.sub(2, 1);
verify(deprecatedMethodsMock, times(0)).collect(any(JoinPoint.class));
}
}

The error occurs only when adding the mongo-scala-driver_2.11 dependency. Without this dependency, the jar will be built. My code is currently the Pi-Estimation example from the Spark website:
val conf = new SparkConf()
.setAppName("Cluster Application")
//.set("spark.serializer", "org.apache.spark.serializer.KryoSerializer")
val sc = new SparkContext(conf)
val count = sc.parallelize(1 to NUM_SAMPLES).map{i =>
val x = Math.random()
val y = Math.random()
if (x*x + y*y < 1) 1 else 0
}.reduce(_ + _)
println("Pi is roughly " + 4.0 * count / NUM_SAMPLES)
I also tried adding the following tags to each element as I found this in some github issue. Did not help though.
<exclusions>
<exclusion>
<!-- make sure wrong scala version is not pulled in -->
<groupId>org.scala-lang</groupId>
<artifactId>scala-library</artifactId>

How to fix this? The MongoDB Scala Driver seems to be built against Scala 2.11 but Spark requires Scala 2.10.
Remove the Mongo Scala Driver dependency, its not compiled for Scala 2.10 and therefore not compatible.
The good news is MongoDB Spark Connector is a standalone connector. It utilises the synchronous Mongo Java Driver because Spark is designed for CPU intensive synchronous tasks. It has been designed to follow Spark idioms and is all that is needed to connect MongoDB to Spark.
On the other hand the Mongo Scala Driver is idiomatic to modern Scala conventions; all IO is fully asynchronous. This is great for web applications and improving the scalability of an individual machine.

Where would I find jdbc.artifact.groupid and what is missing in my pom.xml?
You must replace jdbc.artifact.groupid:jdbc-driver:1.0 by a real vendor artifact. For instance
<dependency>
<groupId>org.hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<version>2.2.8</version>
</dependency>
if you use hsqldb.
EDIT
As you mention you use Oracle in your comment... The jdbc jar for Oracle db is provided with your Oracle distribution. You can also download it here.Once downloaded you will have to put it manually in your local maven repo (you can also store it in the thirparty repo of you Maven Repo Manager if you have one (Nexus, Archiva...). An other way is to add the dependency by using the systemPath declaration :
<dependency>
<groupId>com.oracle.jdbc</groupId>
<artifactId>ojdbc6_g</artifactId>
<version>11.2.0.2.0</version>
<systemPath>"C:/ThirpartyJars/Oracle/ojdbc6_g.jar"</systemPath>
</dependency>
Replace your dependency
<dependency>
<groupId>jdbc.artifact.groupid</groupId>
<artifactId>jdbc-driver</artifactId>
<version>1.0</version>
</dependency>
to
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>11.2.0</version>
</dependency>
