File not found Maven

Question

I am having some problems with simple cloud storage (simplecloud). When I run with Maven the console outputs following error :

java.io.FileNotFoundException: \var\key (The system cannot find the path specified)

Source code is here : src git

However it exists in the directory as shown here :

Any ideas?

Thanks in advance

Answer 1

I suggest you post the related code snippet in your CreateBucketTest.

I believe in your test you are opening a file \var\key. Obviously this is going to cause problem because the file you are thinking of is not really located at \var\key

Some suggestions to you:

1. instead of reading from absolute path, see if you can change it to opening stream for class path resources.

2. Put your key file under src/main/test/resources. Assume you put it under src/main/test/resources/cloudkey/key

3. With the above setup, when you run your test, the key file will be under the classpath at location /cloudkey/key

---

Edit:

After reading a bit on your code, here are some suggestions:

First, your getStorage relies on system property which is not very test friendly. Consider writing your code in a more test-friendly way

However I believe you are not going to refactor your code anyway, here is one way you can do:

1. put key in /src/test/resources. By doing so, when compiled, key will be put to BASE_DIR/target/test-classes/key.
2. Here I assume you will have only 1 key for all your tests. What you need to do is to set the system property private.key.path with the correct path of key. You can do so by configuring surefire plugin : http://maven.apache.org/surefire/maven-surefire-plugin/examples/system-properties.html. Add a systemPropertyVariables private.key.path with value ${project.build.testOutputDirectory}/key. By doing so, when your test is running, the sys property private.key.path will be set with the correct value, so that your test should run fine.

Answer 2

Make sure your \var\key directory is present in the target directory that Maven creates for the build. I'll go out on a limb and guess that it's probably not there now. If you have to have that \var\key in a non-standard place, you can use the Maven Resources Plugin to copy it into the target directory. As @Adrian Shum suggests, test\resources would be a standard place for Maven to look to find it.

EDIT:

Seems like you wanted to explore this option, so here's how you might use the Maven Resources Plugin in your Maven POM...

Inside the plugins node under build, add:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-resources-plugin</artifactId>
  <version>2.6</version>
</plugin>

Then after the plugins node again inside build, add the directory or directories you need to copy over to target, for example:

<resources>
    <resource><directory>src/main/resources</directory></resource>
</resources>
<testResources>
    <testResource><directory>src/var/key</directory></testResource>
    <testResource><directory>src/test/resources</directory></testResource>
</testResources>

Answer 3

Remove the initial \. Also, as pointed out by the others, as this is obviously a test key (judging by the name), you should place it under src/test/resources/var/key and change your code to look for just var/key/test.p12.
