I am using maven in my project & I've put database.properties file under
maven resources folder.
I am accessing it in spring application context
<context:property-placeholder location="classpath:database.properties" />
But I don't understand why I am getting this file not found error on server start.
Could not load properties; nested exception is
java.io.FileNotFoundException: class path resource
[database.properties] cannot be opened because it does not exist
To my knowledge whatever resource is put under resources folder it is added to the classpath automatically by maven.

NOTE: Seems like there is some problem with the M2E plugin of eclipse luna. Executed the same code in Juno & it worked fine.
That's not enough to build a deployable war file with maven. You need at least the war plugin. There's a thorough tutorial here:
http://crunchify.com/how-to-create-a-war-file-from-eclipse-using-maven-plugin-apache-maven-war-plugin-usage/
Your pom will look something like below, and you'll need to run mvn clean install against that.
Also I see you have a spring app, where are the spring dependencies in the pom file?

So this is probably a stupid question, but I have created an own library "testlib" which I want to include in other of my own Maven projects.
This is my own librarys .pom

In order to include my library in another new project, I have created a local repository in my new projects .pom
...
<repositories>
<repository>
<id>data-local</id>
<name>data</name>
<url>file://${project.basedir}/repo</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>com.test.testlib</groupId>
<artifactId>testlib</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
</dependencies>
...
Installing my own library "testlib" via mvn install is working fine for testlib itself. The problem is, that Maven will not detect that "testlib" requires org.slf4j, hence won't get it when I run install.
I have checked other dependencies in my .m2 folder and saw they have a .pom file with the same name as the .jar (for log4j that'd be log4j-1.2.17.pom). I tried copying testlibs .pom next to its .jar and changed the name accordinly, but that doesn't do it.
What do I have to do in order to get the same functionality as any other library from maven central? In other words, I don't want a fat .jar that has all dependencies included. I want a Maven project that adds my library as a dependency to discover that it needs sl4j and include it when mvn install is run.
I am trying to test the basic structure of my GUI application that I started using WindowBuilder. I am also using Maven so that I can just download the dependencies from their repository.
I don't have any errors when I do a "Maven Clean" or a "Maven Install", but when I try to do "Run As--->Java Application", I get the following error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: no swt-win32-3044 in java.library.path
swt-win32-3044 was what I found in the Maven Repository to satisfy the requirements for the WindowBuilder. I don't have any errors in my POM file, but here is what I have...

Any help would be greatly appreciated. Thanks.
So I changed the POM around a little bit. I tried a different Maven dependency for WindowBuilder and changed my syntax for defining the maven-surefire-plugin.

It now launches the Java application window as expected.
I'm very new to maven, so kindly bear with me.
i have a maven project with almost 100 dependencies all of which are present in my local system. So I'm adding them to my classpath via pom.xml with <scope> being system and <systemPath> giving path to the said dependencies. A rough structure of my pom.xml looks like this:

This includes all the jars into my classpath and everything is running fine.
But i would like to keep the path/to/directory/outside/project/directory/ inside my app.propeties file and pom.xml should fetch this path from the properties file.
Is there a way in maven to do this.
Could somebody help me here. Thanks in advance.
i'm stuck with a problem and can't figure what's wrong.
I have a multi-module maven project, using spring boot.
Layout of the project
I'm using STS, and everything is fine. If i run the app, it runs the server, and i have my index in localhost:8080.
However, i'd like to generate a jar from this. So, i'm using mvn clean install. It generates a jar in /target. The layout in the jar is fine, with the source, and the source of the client.
Then, i'm running my jar with java -jar myJar.jar. The server runs properly, but when i'm trying to access to the site, i have an error 404. It can't find the views.
The error :
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Wed Dec 28 19:45:52 CET 2016
There was an unexpected error (type=Not Found, status=404).
No message available
Here's my pom.xml of the web and client module.

I've search over stackoverflow but haven't find anything :/
If you need more details or code, ask me i'll edit.
Thanks !
Please check if you have any method attached to the url your are hitting from the browser. 404 - not found, the resource or url you are trying to access does not exists. You should have a Method of a controller mapped to "/" or whatever url you are hitting.
I have Eclipse Indigo and M2E plugin installed.
So essentially I have a standard maven web project (let's call it proj-service) that is built into a war file in the package phase. This all works fine. My issue comes in when I have my other project (lets call it proj1) that needs to use classes from proj-service. I know that this is possible in maven+eclipse but it does not seem to be working at the moment. I have the following in proj1's pom right now:
<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/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.mycompany.foo</groupId>
<artifactId>proj1</artifactId>
<packaging>war</packaging>
<version>1.0</version>
<name>proj1</name>
<properties>
<spring.version>3.1.0.RELEASE</spring.version>
</properties>
<dependencies>
<!-- Maven Repo Libraries -->
.........
<!-- Interproject dependencies -->
<dependency>
<groupId>com.mycompany.foo</groupId>
<artifactId>proj-service</artifactId>
<version>1.0</version>
<type>war</type>
</dependency>
</dependencies>
<build>
<finalName>lsoap</finalName>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
</plugins>
</build>
</project>
Unfortunately with Maven's war packaging you can't reuse classes from war project, because there is no direct build artifact you can use for the class path.
So, in order to do share classes properly you need to extract those common classes into a 3rd common project (jar packaging) and make it as dependency in both of your other projects.
First you have to change the configuration of your proj-service project in the way to change the configuration of the maven-war-plugin:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<attachClasses>true</attachClasses>
<archiveClasses>true</archiveClasses>
...
</configuration>
</plugin>
This will it make possible to use the classes from the proj-service project in other projects via the following dependencies:
<dependency>
<groupId>myGroup</groupId>
<artifactId>myArtifact</artifactId>
<version>myVersion</myVersion>
<classifier>classes</classifier>
</dependency>
This will result in changing your dependency from:
<dependency>
<groupId>com.mycompany.foo</groupId>
<artifactId>proj-service</artifactId>
<version>1.0</version>
<type>war</type>
</dependency>
into:
<dependency>
<groupId>com.mycompany.foo</groupId>
<artifactId>proj-service</artifactId>
<version>1.0</version>
<classifier>classes</classifier/>
</dependency>
