From mobile apps to microservices, from small startups to big enterprises, Gradle helps teams build, automate and deliver better software, faster.

No, what you do should work fine as far as you showed details.

Maybe your program detects that no terminal is attached and thus does not produce output or whatever. Hard to guess with that little information :slightly_smiling_face:

OK, alternative question.  I was trying to get a runnable jar so that I could just run it outside of gradle, and added the last section of this file.  But it can't be parsed, with an error on "jar {".

```plugins {
    // This subproject will be an application.
    id 'application'
}


repositories {
    // We will be able to find dependencies here.
    mavenCentral()
}

dependencies {
    // This subproject will be using the musearchtools library (another subproject).
    implementation project(':musearchtools')
    // This subproject will be using the jsoup library.
    implementation 'org.jsoup:jsoup:1.15.3'
    // The tests for this application will use JUnit 4.
    testImplementation 'junit:junit:4.13.2'
}

application {
    mainClass = 'edu.millersville.csci406.spring2023.CrawlerMain'
}

jar {
    manifest {
        attributes {
            'Main-Class': application.mainClass
        }
    }
}```

Imho trying to create a runnable jar is already the worst you can try.
Especially when you already apply the `application` plugin that can build you a proper distribution.

Just remove the whole `jar` block and use the tasks of the `application` plugin like `distTar` or `distZip` to create a distributable archive with your code, your dependencies, and generated start scripts that properly run your application

Ok, thanks, I'll look into that.  And just making my application write its data to a file directly instead of standard out.

Btw. regarding the actual last question about the syntax problem, another personal recommendation, use Kotlin DSL.
You immediately get type-safe build scripts, proper error messages if you mess up the syntax opposed to Groovy DSL, and amazingly better IDE support if you use a proper IDE like IntelliJ.

Then it would maybe be better obvious that you should have had round parentheses, not curly braces after that `attributes` :slightly_smiling_face:

Thanks, I'll do that too.  But as for my immediate needs, I randomly tried adding parenthesis to create `(./gradlew :mucrawer:run 2&gt;&amp;1) | tee crawler.log` and with the parenthesis I *am* capturing all of the output that I want.

Sounds strange.
Those parens you show execute the content in a subshell.
Maybe your shell is somehow configured to suppress some streams or something like that.
(you wouldn't be the first, I've seen it with others before)
