+## Compiler options
+
+You can configure compiler options in your projects at three different levels:
+
+* **Extension level**, by using it as a top-level block.
+* **Target level**.
+* **Compilation unit level**, usually a specific compilation task.
+
+{width=700}
+
+Settings at a higher level work as defaults for the level below:
+
+* Compiler options set at the extension level are the default for target-level options, including shared source sets like `commonMain`, `nativeMain`, and `commonTest`.
+* Compiler options set at the target level are the default for options at the compilation unit (task) level, like `compileKotlinJvm` and `compileTestKotlinJvm` tasks.
+
+Configurations made at a lower level override similar settings at higher levels:
+
+* Task-level compiler options override similar settings at the target or extension level.
+* Target-level compiler options override similar settings at the extension level.
+
+For the list of possible compiler options, see [All compiler options](gradle-compiler-options.md#all-compiler-options).
+
+### Extension level
+
+To configure compiler options for all targets in your project, use the `compilerOptions {}` block at the top level:
+
+
+
+
+```kotlin
+kotlin {
+ // Configures all compilations of all targets
+ compilerOptions {
+ allWarningsAsErrors.set(true)
+ }
+}
+```
+
+
+
+
+```groovy
+kotlin {
+ // Configures all compilations of all targets:
+ compilerOptions {
+ allWarningsAsErrors = true
+ }
+}
+```
+
+
+
+
+### Target level
+
+To configure compiler options for a specific target in your project, use the `compilerOptions {}` block inside the target block:
+
+
+
+
+```kotlin
+kotlin {
+ jvm {
+ // Configures all compilations of the JVM target
+ compilerOptions {
+ allWarningsAsErrors.set(true)
+ }
+ }
+}
+```
+
+
+
+
+```groovy
+kotlin {
+ jvm {
+ // Configures all compilations of the JVM target
+ compilerOptions {
+ allWarningsAsErrors = true
+ }
+ }
+}
+```
+
+
+
+
+### Compilation unit level
+
+To configure compiler options for a specific compilation, use the `compilerOptions {}` block inside the `compilations` object:
+
+
+
+
+```kotlin
+kotlin {
+ jvm {
+ val main by compilations.getting {
+ compilerOptions.configure {
+ // Configures the 'main' compilation:
+ allWarningsAsErrors.set(true)
+ }
+ }
+ }
+}
+```
+
+
+
+
+```groovy
+kotlin {
+ jvm {
+ compilations.main.compilerOptions.configure {
+ // Configures the 'main' compilation:
+ allWarningsAsErrors = true
+ }
+ }
+}
+```
+
+
+
+
+To configure compiler options for a specific task, use the `compilerOptions {}` block inside the task:
+
+
+
+
+```kotlin
+task.named("compileKotlinJvm"){
+ compilerOptions {
+ allWarningsAsErrors.set(true)
+ }
+}
+```
+
+
+
+
+```groovy
+task.named("compileKotlinJvm"){
+ compilerOptions {
+ allWarningsAsErrors = true
+ }
+}
+```
+
+
+
