CSV file for DryMode not found when executing from .jar

[sebasira]

Release number
v5.0.6

Describe the bug
I've created a .jar file and when executing it like

java -jar test.jar

There's a log entry saying that the user-trade.csv file can not be found

2021-12-04 21:58:43.194 ERROR 26366 --- [           main] t.c.t.b.util.dry.UserServiceDryModeAOP   : user-trade.csv not found !

I have no problem when debugging from the IDE. What's strange is that the file is present inside the .jar and I've also put it outside the .jar, in the same directoy

To Reproduce
I can only reproduce it when running the external jar

Expected behavior
I would expect the file to be picked up and the fake account will be configured

Screenshots
Here you can see the CSV inside the .jar

@sebasira Hi ! why do you want to make a jar with those kinds of files included ?

@sebasira Hi ! why do you want to make a jar with those kinds of files included ?

I don't! I just want to make a .jar and test the dry mode in a cloud server. The problem is that the compiled .jar does not pickup the .csv so I try leaving it inside the jar (this setup is the one I have when debugging from the IDE, I have the .csv in the resource folder).

I also try with the .csv file outside the .jar next to it in the same directory but still it won't be picked up.

I'm thinking the file path could be the problem when loading the file with Scanner

@sebasira indeed, when making a jar, the files in src/test are not taken. Can you move your csv files to src/main/resources ?

[sebasira]

They are already at src/main/resources.

From the screenshot of the first post, you can see that the the generate jar has the CSV

[sebasira]

I've try to add a log entry at the point where Scanner try to pick the file up, so I can log the file path, but I'm having trouble compiling the project. I'm used to gradle rather than maven.

@sebasira you can build and isntall cassandre release by typing: mvn install -Dgpg.skip -DskipTests

[straumat]

@sebasira can you tell me the command you used to create the jar ? Thx

[sebasira]

I'm sorry I do not know much about Maven and after executing the command you proposed:

mvn install -Dgpg.skip -DskipTests

I add it to my project and all I get is an empty .jar

I can not build the project to test and work on it.

See:

@sebasira i'm sorry. My question was, what command did you use to build your test.jar ?

[sebasira]

Oh I see!

I've built my app with gradle wrapper using

./gradlew build

[straumat]

@sebasira did you try with this https://stackoverflow.com/a/52404325

[sebasira]

I manage to build this project (maven) and use the SNAPSHOT version of Cassandre in my test app. I'll try with a log entry where Scanner looks for the file and get back in touch

[sebasira]

Well... I'm back...

This entire comment is about this line

After a lot and a lot and a lot of testing here's what I've found out:

1- I couldn't find (yet) a method that works for both: file in the resource folder and file outside the .jar, next to it.

2- The actual code:

Scanner scanner = new Scanner(file.getFile())

only works (at least for me) when debugging the app. I mean run it from the IDE (IntelliJ)

3- Replacing it with:

Scanner scanner = new Scanner(file.getInputStream())

works with the complied .jar but only looks for the file user-trade.csv inside the resource folder within the jar

4- Using this other line:

Scanner scanner = new Scanner(new FileReader(file.getFilename()))

Does not load the file inside the resource folder, but read the outer file, sitting next to the .jar file

At this point my idea is to:

• Try to load the file from outside the .jar according to (4). If that fails because there's no file outside the .jar try looking for it inside the .jar, according to (3). If that fails, then we can assure there's no file to be found

@sebasira don't you think the problem come from this method:

    private List<Resource> getFilesToLoad() {
        PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
        try {
            final Resource[] resources = resolver.getResources("classpath*:" + USER_FILE_PREFIX + "*" + USER_FILE_SUFFIX);
            return Arrays.asList(resources);
        } catch (IOException e) {
            logger.error("UserServiceDryModeAOP encountered an error: " + e.getMessage());
        }
        return Collections.emptyList();
    }
