The section in the README "Updating for offline use" is redundant.

Once you have run the project once all your dependencies will be cached locally by gradle anyway.

This section is misleading and redundant and should be removed.

You should also remove the following lines in the build.gradle

https://github.com/corda/bootcamp-cordapp/blob/v4/build.gradle#L16
flatDir { dirs "lib/dependencies" }

https://github.com/corda/bootcamp-cordapp/blob/v4/build.gradle#L20
classpath fileTree(dir: 'lib/dependencies', include: '*.jar')

https://github.com/corda/bootcamp-cordapp/blob/v4/build.gradle#L35
flatDir { dirs "${project.rootProject.projectDir}/lib/dependencies" }

https://github.com/corda/bootcamp-cordapp/blob/v4/build.gradle#L66
compileClasspath fileTree(dir: 'lib/dependencies', include: '*.jar')

https://github.com/corda/bootcamp-cordapp/blob/v4/build.gradle#L131-L139

task gatherDependencies(type: Copy) {
    into "lib/dependencies"
    from buildscript.configurations.classpath
    from configurations.runtime
    from configurations.compile
    from configurations.testCompile
    from configurations.testRuntime
    from configurations.quasar
}

Sorry to bother you....I really encounter trouble.
In the begining, when I want to run ProjectImportedOKTest, the intellJ idea will tell me:

next, I choose
Use classpath of module:bootcamp-cordapp-4
JRE to be 1.8,
like the next picture, however, the intellJ idea will still tell me:

Warning:Class 'ProjectImportedOkTest' not found in module 'bootcamp-cordapp-4'
If I choose the other options, the intellJ idea will still warn me, could you tell me how to solve it?

sorry to bother, not only I'm a beginner of corda, but also one of java.

Feel free to split this out into lots of smaller issues.

Referring to the v4 branch.

The wrong version of corda is specified:

corda_release_version = '4.0-SNAPSHOT'
corda_gradle_plugins_version = '4.0.37'

There are unnecessary repos.

mavenLocal() is only useful for R3 developers using snapshots.

flatDir { dirs "lib/dependencies" } is completely unnecessary see #6 for further details

This whole section should be removed
https://github.com/corda/bootcamp-cordapp/blob/v4/build.gradle#L52-L63

sourceSets {
    main {
        resources {
            srcDir "../config/dev"
        }
    }
    test {
        resources {
            srcDir "../config/test"
        }
    }
}

In this particular case there is only one module so you don't need it anyway.

In the general case it causes circular dependencies in IDEs and confusion with users as evidenced on Slack.
The only purpose of it is to not duplicate logging config.

https://github.com/corda/bootcamp-cordapp/blob/v4/build.gradle#L83
deployNodesJava can just be deployNodes like the kotlin project.

https://github.com/corda/bootcamp-cordapp/blob/v4/build.gradle#L84
directory "./build/nodes" is the default so doesn't need to be specified.

https://github.com/corda/bootcamp-cordapp/blob/v4/build.gradle#L90
"$project.group:cordapp:$project.version" the project name is not cordapp

There is no gradle.properties specifying the project group, name, version.

There is no need to repeat the cordapp[] section in each node when you could do:

    nodeDefaults {
        projectCordapp {
            deploy = true
        }
    }

Why are there no rpc settings for the notary?

This line's exception comments is about output requirement. But getInputs() is used.

Can you please help me with the issue.

Hi, I was following the bootcamp videos and on video 17 Corda Bootcamp 17 - Flows Exercises I ran into this error why running FlowTests.

I did try to edit configurations as the video suggests, but still the same error (which is different than the error presented in the video).
Also worth noting that I only get the same error after adding the configuration if I try to run an individual test. If I try to run the entire class, I get the message "Test events were not received".

Any idea on what might be the reason?

It would be convenient if the web resources links were clickable. e.g.
"Key Concepts docs (docs.corda.net/key-concepts.html)"

In "Running our CorDapp" the deployNodes gradle target is wrong
says:
macOS: ./gradlew deployNodesJava
should be:
macOS: ./gradlew deployNodes

possibly same for windows - can't comment :)

Is it really necessary to store this big file in the source code?
https://github.com/corda/bootcamp-cordapp/blob/master/gradle/wrapper/gradle-4.4.1-all.zip

I am using JDK 1.8 version and following all the README.md steps.
On running the nodes, pop up windows come for Notary, PartyA, PartyB and PartyC properly.

Terminal for PartyA - trying to issue the amount to PartyC

Fri Jun 12 11:13:47 IST 2020>>> start TokenIssueFlowInitiator owner: PartyC, amount: 1000
Starting

Terminal for PartyC - trying to check the vault of PartyC

Fri Jun 12 11:16:17 IST 2020>>> run vaultQuery contractStateType: bootcamp.TokenState
RPC failed: net.corda.core.CordaRuntimeException: java.lang.IllegalArgumentException: bootcamp.TokenState is not a net.corda.core.contracts.ContractState

This error is actually coming for all the nodes.

TokenState.java - This file has TokenState implementing ContractState

@BelongsToContract(TokenContract.class)
public class TokenState implements ContractState {
    private final Party issuer;
    private final Party owner;
    private final int amount;
    private final List<AbstractParty> participants;

    public TokenState(Party issuer, Party owner, int amount){
        this.issuer = issuer;
        this.owner = owner;
        this.amount = amount;
        this.participants = new ArrayList<>();
        participants.add(issuer);
        participants.add(owner);
    }

    @NotNull
    @Override
    public List<AbstractParty> getParticipants() {
        return Arrays.asList(issuer, owner);
    }

    public Party getIssuer() {
        return issuer;
    }

    public Party getOwner() {
        return owner;
    }

    public int getAmount() {
        return amount;
    }
}

What could be the issue here?
