API Documentation: | JavaPluginExtension |
---|
Common configuration for JVM (Java) based projects.
This extension is added by the JavaBasePlugin
and would be more appropriately named
the JvmPluginExtension
extension. It is used to configure many of the project's
JVM-related settings and behavior.
Property | Description |
docsDir | Returns a file pointing to the root directory supposed to be used for all docs. |
sourceCompatibility | The source compatibility used for compiling Java sources. |
sourceSets | The source sets container. |
targetCompatibility | The target compatibility used for compiling Java sources. |
testReportDir | Returns a file pointing to the root directory to be used for reports. |
testResultsDir | Returns a file pointing to the root directory of the test results. |
toolchain | Gets the project wide toolchain requirements that will be used for tasks requiring a tool from the toolchain (e.g. |
Method | Description |
disableAutoTargetJvm() | If this method is called, Gradle will not automatically try to fetch dependencies which have a JVM version compatible with the target compatibility of this module. |
manifest() | Creates a new instance of a |
manifest(closure) | Creates and configures a new instance of a |
manifest(action) | Creates and configures a new instance of a |
registerFeature(name, configureAction) | Registers a feature. |
toolchain(action) | Configures the project wide toolchain requirements for tasks that require a tool from the toolchain (e.g. |
withJavadocJar() | Adds a task |
withSourcesJar() | Adds a task |
Block | Description |
sourceSets | Configures the source sets of this project. |
DirectoryProperty
docsDir
Returns a file pointing to the root directory supposed to be used for all docs.
- Default with
java
plugin: ${project.layout.buildDirectory}
/docs
JavaVersion
sourceCompatibility
The source compatibility used for compiling Java sources.
- Default with
java
plugin: - Value of the current used JVM (e.g.
JavaVersion.JAVA_1_6
on a 1.6 JVM).
SourceSetContainer
sourceSets
(read-only)
The source sets container.
JavaVersion
targetCompatibility
The target compatibility used for compiling Java sources.
- Default with
java
plugin: project.sourceCompatibility
DirectoryProperty
testReportDir
Returns a file pointing to the root directory to be used for reports.
- Default with
java
plugin: ${project.reporting.baseDir}
/tests
DirectoryProperty
testResultsDir
Returns a file pointing to the root directory of the test results.
- Default with
java
plugin: ${project.layout.buildDirectory}
/test-results
JavaToolchainSpec
toolchain
(read-only)
Gets the project wide toolchain requirements that will be used for tasks requiring a tool from the toolchain (e.g. JavaCompile
).
Configuring a toolchain cannot be used together with sourceCompatibility
or targetCompatibility
on this extension.
Both values will be sourced from the toolchain.
If this method is called, Gradle will not automatically try to fetch dependencies which have a JVM version compatible with the target compatibility of this module.
This should be used whenever the default behavior is not applicable, in particular when for some reason it's not possible to split a module and that this module only has some classes which require dependencies on higher versions.
Creates and configures a new instance of a Manifest
. The given closure configures
the new manifest instance before it is returned.
Creates and configures a new instance of a Manifest
.
void
registerFeature
(String
name, Action
<? super FeatureSpec
>
configureAction)
Action
<? super FeatureSpec
>Registers a feature.
The new feature will have a default capability corresponding to the "group", "name" + feature name and version of this project. For example, if the group of the component is "org", that the project name is "lib" the version is "1.0" and the feature name is "myFeature", then a capability named "org:lib-my-feature:1.0" is automatically added.
In order to consume this feature in another module add a dependency like the following:
dependencies { implementation(project(":lib")) { capabilities { requireCapability("org:lib-my-feature:1.0") } } }
The FeatureSpec.capability(java.lang.String, java.lang.String, java.lang.String)
method can be
used to refine the capabilities of this feature.
JavaToolchainSpec
toolchain
(Action
<? super JavaToolchainSpec
>
action)
Action
<? super JavaToolchainSpec
>Configures the project wide toolchain requirements for tasks that require a tool from the toolchain (e.g. JavaCompile
).
Configuring a toolchain cannot be used together with sourceCompatibility
or targetCompatibility
on this extension.
Both values will be sourced from the toolchain.
Adds a task javadocJar
that will package the output of the javadoc
task in a JAR with classifier javadoc
.
The produced artifact is registered as a documentation variant on the java
component and added as a dependency on the assemble
task.
This means that if maven-publish
or ivy-publish
is also applied, the javadoc JAR will be published.
If the project already has a task named javadocJar
then no task is created.
The publishing of the Javadoc variant can also be disabled using ConfigurationVariantDetails.skip()
through AdhocComponentWithVariants.withVariantsFromConfiguration(org.gradle.api.artifacts.Configuration, org.gradle.api.Action)
,
if it should only be built locally by calling or wiring the ':javadocJar' task.
Adds a task sourcesJar
that will package the Java sources of the main SourceSet
in a JAR with classifier sources
.
The produced artifact is registered as a documentation variant on the java
component and added as a dependency on the assemble
task.
This means that if maven-publish
or ivy-publish
is also applied, the sources JAR will be published.
If the project already has a task named sourcesJar
then no task is created.
The publishing of the sources variant can be disabled using ConfigurationVariantDetails.skip()
through AdhocComponentWithVariants.withVariantsFromConfiguration(org.gradle.api.artifacts.Configuration, org.gradle.api.Action)
,
if it should only be built locally by calling or wiring the ':sourcesJar' task.
Configures the source sets of this project.
The given closure is executed to configure the SourceSetContainer
. The SourceSetContainer
is passed to the closure as its delegate.
See the example below how SourceSet
'main' is accessed and how the SourceDirectorySet
'java'
is configured to exclude some package from compilation.
plugins { id 'java' } sourceSets { main { java { exclude 'some/unwanted/package/**' } } }
