            org.apache.maven.shared.dependency.graph.DependencyGraphBuilder dependencyGraphBuilder,
            org.apache.maven.plugin.logging.Log log)

Method Detail

hasStaticNativeLibraryArtifact

public static boolean hasStaticNativeLibraryArtifact(Set<org.apache.maven.artifact.Artifact> resolveNativeLibraryArtifacts)

hasSharedNativeLibraryArtifact

public static boolean hasSharedNativeLibraryArtifact(Set<org.apache.maven.artifact.Artifact> resolveNativeLibraryArtifacts)

getNativeDependenciesArtifacts

public Set<org.apache.maven.artifact.Artifact> getNativeDependenciesArtifacts(boolean sharedLibraries)
                                                                       throws org.apache.maven.plugin.MojoExecutionException

Throws:

org.apache.maven.plugin.MojoExecutionException

validateNDKVersion

public static void validateNDKVersion(File ndkHomeDir)
                               throws org.apache.maven.plugin.MojoExecutionException

Throws:

org.apache.maven.plugin.MojoExecutionException

validateNDKVersion

public static void validateNDKVersion(int desiredVersion,
                      String versionStr)
                               throws org.apache.maven.plugin.MojoExecutionException

Throws:

org.apache.maven.plugin.MojoExecutionException

getAppAbi

public static String[] getAppAbi(File applicationMakefile)

extractArchitectureFromArtifact

public static String extractArchitectureFromArtifact(org.apache.maven.artifact.Artifact artifact,
                                     String defaultArchitecture)

Extracts, if embedded correctly, the artifacts architecture from its classifier. The format of the classifier, if including the architecture is <architecture>-<classifier>. If no architecture is embedded in the classifier, 'armeabi' will be returned.

Parameters:

artifact - The artifact to retrieve the classifier from.

defaultArchitecture - The architecture to return if can't be resolved from the classifier

Returns:

The retrieved architecture, or defaulArchitecture if not resolveable

getNdkArchitectures

public static String[] getNdkArchitectures(String ndkArchitectures,
                           String applicationMakefile,
                           File basedir)
                                    throws org.apache.maven.plugin.MojoExecutionException

Attempts to extract, from various sources, the applicable list of NDK architectures to support as part of the build.

It retrieves the list from the following places:

• ndkArchitecture parameter
• projects Application.mk - currently only a single architecture is supported by this method

Parameters:

ndkArchitectures - Space separated list of architectures. This may be from configuration or otherwise

applicationMakefile - The makefile (Application.mk) to retrieve the list from.

basedir - Directory the build is running from (to resolve files)

Returns:

List of architectures to be supported by build.

Throws:

org.apache.maven.plugin.MojoExecutionException

artifactHasHardwareArchitecture

public static boolean artifactHasHardwareArchitecture(org.apache.maven.artifact.Artifact artifact,
                                      String ndkArchitecture,
                                      String defaultArchitecture)

Helper method for determining whether the specified architecture is a match for the artifact using its classifier. When used for architecture matching, the classifier must be formed by <architecture>-<classifier>. If the artifact is legacy and defines no valid architecture, the artifact architecture will default to armeabi.

Parameters:

ndkArchitecture - Architecture to check for match

artifact - Artifact to check the classifier match for

Returns:

True if the architecture matches, otherwise false

isNativeArtifactProject

public static boolean isNativeArtifactProject(org.apache.maven.project.MavenProject mavenProject)

Checks whether or not the specified project provides a native library artifact as its primary artifact.

Parameters:

mavenProject - Project to check

Returns:

True if the packaging of the project is either "a" or "so" (both defining native artifacts).

listNativeFiles

public static File[] listNativeFiles(org.apache.maven.artifact.Artifact artifact,
                     File unpackDirectory,
                     boolean staticLibrary,
                     String architecture)
