Google AdSense​

In a localhost development environment, this error is normal:

Failed to load resource: the server responded with a status of 403 ()

JavaScript​

Double negation (!!)​

!! coerces a value to a boolean:

!!null       // false

# Check the React version

Gradle​

Source folder inside lib in an Eclipse Gradle project​

The New Gradle Project dialog invokes the Gradle init task with the hard-coded argument --type java-library, and the project layout differs for Gradle versions above 6.6.1. Using gradle init, remove the include in settings.gradle and move everything from src to the root path.

Could not run phased build action​

Delete C:\Users\$USER\.gradle.

Ignore JUnit 4 in Gradle and Maven​

testImplementation('org.springframework.boot:spring-boot-starter-test') {
    exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
}

Track down which dependency pulls it in:

./gradlew dependencyInsight --dependency "junit:junit" --configuration "testCompileClasspath"

Or exclude it in one place:

/* for all the configurations */
configurations {
  all {
    /* only junit 5 should be used */
    exclude group: 'junit', module: 'junit'
    exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
  }
}

/* for particular test configurations */
configurations {
  testCompile {
    exclude group: 'junit', module: 'junit'
    exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
  }
  testRuntime {
    exclude group: 'junit', module: 'junit'
    exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
  }
}

Tailwind CSS​

Setting up Tailwind on Windows with VS Code (win-node-env may already be installed):

"build:tailwind-prod": "NODE_ENV=production postcss src/style.css -o dist/css/style.min.css"
