加载Maven-surefire-plugin的属性文件

Question

I have a testng class which tests a class which in turns load property from classpath.When i run maven install i am getting an error mentioning file not found.It is not able to find the property file though i have it in src/test/resources . How to resolve this issue?

the java code is having a constructor which tries to load the property file Properties props = JobUtils .loadProperties("x.properties"); my maven configuration:

<plugin>
  <groupId>org.apache.maven.plugins
  <artifactId>maven-surefire-plugin
  <version>2.5
  <configuration>
    <skipTests>false</skipTests>
  </configuration>
</plugin>

with:

<build>
  <testResources>
    <testResource>
      <directory>src/test/resources</directory>
      <filtering>false</filtering>
    </testResource>
  </testResources>
</build>

Also I have this x.properties in src/test/resource

Stack trace Running TestSuite is:

java.io.FileNotFoundException: x.properties (The system cannot find the file specified)
   at java.io.FileInputStream.open(Native Method)
   at java.io.FileInputStream.(FileInputStream.java:106)
   at java.io.FileInputStream.(FileInputStream.java:66)

Also note the test class i have tries to instantiate this java code and test it.

Your x.properties file from the src/test/resources directory is actually being copied to the target/test-classes directory after the Maven process-test-resources phase is executed. So if you want your application to be able to find it, you should use the following file-path:

Properties props = JobUtils .loadProperties("target/test-classes/x.properties");

However I do not think this is exactly what you are looking for. I recommend to read the property file directly from the CLASSPATH (without using the file-system directly) using a code like this:

InputStream is = getClass().getResourceAsStream("/x.properties");
Properties p = new Properties();
try {
  p.load(is);
} catch (IOException e) {
  e.printStackTrace();
} finally {
  if (is != null) {
    try {
      is.close();
    } catch (IOException e) {
      e.printStackTrace();
    }
  }
}

Using this approach you will be able to load the property file even from within a JAR file distributed to the customer or also from a configuration file that is added to the CLASSPATH in some kind of a launch-script.

I had the same problem of a file not being found. However, I got to a point where I realized that maven found it for use when I ran mvn test on the command line. It was just my Eclipse IDE telling me it can't find it. When I changed in my IDE directory src/test/resources into a "source directory", then my IDE was fine too.
