I'm working on a bot that automatically reports it's profit to a Google Sheet. I got it working in debug mode with IntelliJ but when I run the compiled jar I get this error. 

Failed to start script [Sheets]

I'm using maven and following dependencies: 

        <dependency>
            <groupId>com.google.api-client</groupId>
            <artifactId>google-api-client</artifactId>
            <version>1.30.4</version>
        </dependency>
        <dependency>
            <groupId>com.google.auth</groupId>
            <artifactId>google-auth-library-oauth2-http</artifactId>
            <version>0.23.0</version>
        </dependency>
        <dependency>
            <groupId>com.google.apis</groupId>
            <artifactId>google-api-services-sheets</artifactId>
            <version>v4-rev20201130-1.31.0</version>
        </dependency>

My build artifact includes all libraries supplied by maven in its root, though I have also tried all other possible combinations with no success (put into output, extract into output, encapsulate in folder/jar).

Has anyone experienced an issue like this in the past and got it resolved? Please let me know!

Make sure your project source and output are not in the Scripts directory, and only the built jar is going to be there

Extract all dependencies except for OSBot into output jar

Double check that you have nothing in Scripts directory except for the previously built jar

Start a command prompt 

jar tvf <script_jar>

Verify if above contains all dependencies 

java -jar <osbot_jar> -autologin -bot email:pass:1234 -script Sheets:a -debug 0

If the above fails, read the entire stacktrace from cmd and look for security policy exceptions about reflection 

java -jar <osbot_jar> -autologin -allow reflection -bot email:pass:1234 -script Sheets:a -debug 0

java -jar <osbot_jar> -autologin -allow reflection -bot email:pass:1234 -script Sheets:a -debug 0

 

The project source and output is in a different directory and the only file in the Scripts folder is Sheets.jar.

This are the artifact settings:

image.png.6edc05028b1dc67dcedb2c20eec0495d.png At the bottom is also Sheets compile output.

I ran the following command to make sure the dependency it's complaining about is in the jar. 

~/.jdks/adopt-openjdk-1.8.0_282/bin/jar tvf Sheets.jar | grep ServletContextCleaner
  2914 Sun Feb 07 04:14:04 CET 2021 org/apache/commons/logging/impl/ServletContextCleaner.class

Next I ran the following script to launch OSBot with arguments: 

#! /bin/bash
~/.jdks/adopt-openjdk-1.8.0_282/bin/java -jar "OSBot.jar" \
        -autologin \
        -allow reflection \
        -bot xxx \
        -script Sheets:null \
        -debug 0 \
        -proxy xxx \
        -login xxx

And it spit out the following rather long error:

Could not find script : Sheets

Regarding this line: 

[ERROR][02/11 01:57:22 AM]: Failed to load local script : org/apache/commons/logging/impl/ServletContextCleaner.class

using the jar command above I have confirmed the file is in fact inside the jar.

And regarding these lines: 

[ERROR][02/11 01:57:21 AM]: Failed to load local script : module-info.class
java.lang.UnsupportedClassVersionError: module-info has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0

I have no idea why it complains about this because all my IntelliJ settings are set to java 1.8 and the libraries are also confirmed to be working in java 8.

Any further help would be greatly appreciated.

It looks like you are compiling your jar with java 9. Try to add this to your pom 

<properties>
    <maven.compiler.target>1.8</maven.compiler.target>
    <maven.compiler.source>1.8</maven.compiler.source>
</properties>

And compile using maven and see if you still get the same error. If you don't get the same error, then that confirms you compiled using the wrong version. To stick with maven, you may need to use a plugin to include all dependencies though. (Note that the jar won't be in the same directory as when you build directly on intellij unless you set the path)

Any further help would be greatly appreciated.

Either your script or one of the dependencies is not compatible with java 8 (has been compiled with a newer version); for dependencies you can usually find them in multiple versions, both for java 8 and for newer versions
