error: cannot find symbol(Heroku Discord Bot)

I'm trying to make my Discord bot to work on Heroku but I keep getting an error. The build process works fine but the bot doesn't go online. I went to Resources --> More --> View Logs and saw an error. I understood the error as some methods not getting recognized and I removed the error one. But another one would just pop up. The code and bot works on local using IntelliJ. Anyone can help me with this please?
The error/Resource logs:

If you run locally with an IDE like IntelliJ, it will handle things like this to you, but you need add a plugin to create a jar with dependencies before deploying it.

To fix this problem, you'd have to change the pom.xml and Procfile.
Add this line to the pom.xml:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>appassembler-maven-plugin</artifactId>
<version>2.1.0</version>
<configuration>
<assembleDirectory>target</assembleDirectory>
<programs>
<program>
<mainClass>MAIN_CLASS_PATH</mainClass>
<name>BOT_NAME</name>
</program>
</programs>
</configuration>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>assemble</goal>
</goals>
</execution>
</executions>
</plugin>
Add this inside of your plugins tag in your build tag. Change MAIN_CLASS_PATH to your own main class and change BOT_NAME to your project's/bot's name.
Change the Worker for the Procfile to this:
worker: sh target/bin/BOT_NAME
Same thing here ^, change BOT_NAME to your project's/bot's name.

Maven isn't finding your sources, you may not have the directory structure correct. Take a read through http://maven.apache.org/guides/introduction/introduction-to-the-standard-directory-layout.html

I encountered this issue when I had an extra space before the "main" folder. You can check your folder structure and see if it's correct.

successfully building but the wsdl file not found?

i try to generate wsdl file using jaxws maven plugin
finaly:"successfully building" but my wsdl file is not generate, it is normaly in the folder \target\surefire-reports

I would think you would want to build the wsdl in the 'generate-sources' phase or maybe 'generate-resources' instead of 'package'

It is supposed to generate the wsdl in ${resourceDestDir}
Configure it like below with verbose = true, and execute the mvn command with -X flag, then look the maven log carefully.
<executions>
<execution>
<configuration>
<sei>com.ws.BillingAccountRead</sei>
<genwsdl>true</genwsdl>
<keep>true</keep>
<verbose>true</verbose>
</configuration>
<phase>package</phase>
<goals>
<goal>wsgen</goal>

Try to build using -X or -e to get more info from the log

Maven release:prepare goal

We have the following config in our POM file:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<skip>true</skip>
</configuration>
<executions>
<execution>
<id>surefire-it</id>
<phase>integration-test</phase>
<goals>
<goal>test</goal>
</goals>
<configuration>
<skip>false</skip>
</configuration>
</execution>
</executions>
</plugin>
This ensures that the tests are not executed during test phase. Tests are executed only during integration-test phase.
However, when we prepare for release (release:prepare), maven executes the tests during test phase. This causes our build to fail because our tests can be run only during Integration test phase (we use tomcat-maven plugin to deploy the packaged war before the tests can be executed).
I know that we can skip the tests by passing the parameter (-DskipTests etc.). We do not want to skip any tests, we just want release:prepare to execute just like any other maven goal.
Any suggestion/help is highly appreciated.

Try with the more general approach to disable the maven-surefire-plugin completely during test phase.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<executions>
<execution>
<id>default-test</id>
<!-- Disable the default-test by putting it in phase none -->
<phase>none</phase>
</execution>
<execution>
<!-- Enable the test during integration-test phase -->
<id>surefire-it</id>
<phase>integration-test</phase>
<goals>
<goal>test</goal>
</goals>
</execution>
</executions>
</plugin>
Edit
This is the output from my dry run of mvn release:prepare with the above configured surefire plugin:

Add your integration tests in a separate profile which isn't active by default. Add a triggerring rule or something. Then invoke the builds with the integration tests on a need by need basis. For example, on your CI (Jenkins/Hudson, TeamCity, Bamboo, etc) triggered the profile.
The problem you are currently facing is that you haven't made a separation between the two types of tests and when they should run. You have simply defined the phases you would like them to execute in. This isn't sufficient knowledge of the execution context for Maven to figure out what you would like to do and it invokes them during the release as well.

I would try an alternate approach, and try to configure the release plugin to always use -DskipTests as an argument so you don't need to specify it each time:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-release-plugin<artifactId>
<configuration>
<arguments>-DskipTests</arguments>
</configuration>
</plugin>
In theory this should append -DskipTests to the arguments that the prepare and release goals pass to the sub-executions of Maven that they execute.

Use the maven-failsafe-plugin for the integration tests, and keep maven-surefire-plugin for the unit tests.
This will guarantee that the unit tests are completely segregated from the integration tests (and can therefore be turned off separately), and the integration tests are run during the "integration-test and verify phases of the build lifecycle".
