Question

Hello I’m using a configuration file from src/main/resources in my java application. I’m reading it in my Class like this :

new BufferedReader(new FileReader(new File("src/main/resources/config.txt")));

So now I’m building this with maven using mvn assembly:assembly. Here is the bit for that in my pom.xml :

<plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <version>2.3</version>
                <configuration>
                    <finalName>TestSuite</finalName>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                    <archive>
                        <manifest>
                            <addClasspath>true</addClasspath>
                            <mainClass>com.some.package.Test</mainClass>
                        </manifest>
                    </archive>
                </configuration>
            </plugin>

So when I run my app I get this error :

src\main\resources\config.txt (The system cannot find the path specified)

But when I right click on my assembled jar I can see it inside, anyone knows what I’m doing wrong?

Answer 1

Resources from src/main/resources will be put onto the root of the classpath, so you’ll need to get the resource as:

new BufferedReader(new InputStreamReader(getClass().getResourceAsStream("/config.txt")));

You can verify by looking at the JAR/WAR file produced by maven as you’ll find config.txt in the root of your archive.
