Method Detail

readFileDependencyGraph

public static long readFileDependencyGraph(File workFolder,
                                           Map<String,LinkedHashSet<String>> fileDependencies,
                                           Map<String,String> fileAssignedGlobals)
                                    throws org.apache.maven.plugin.MojoExecutionException

Read in an existing dependency graph and return its modification time. We can then check whether a specific dependency needs to be processed again.

Parameters:

workFolder - the folder to look for the dependency file in.

fileDependencies - the dependency graph to read.

fileAssignedGlobals - the assigned globals map to read.

Returns:

the modification time of the file or 0 if no file exists.

Throws:

org.apache.maven.plugin.MojoExecutionException - if we have a problem reading the graph.

writeFileDependencyGraph

public static void writeFileDependencyGraph(File workFolder,
                                            Map<String,LinkedHashSet<String>> fileDependencies,
                                            Map<String,String> fileAssignedGlobals)
                                     throws org.apache.maven.plugin.MojoExecutionException

Write out the file dependency graph for processing by other phases.

Parameters:

workFolder - the folder to write to.

fileDependencies - the dependency graph to write.

fileAssignedGlobals - the assigned globals map to write.

Throws:

org.apache.maven.plugin.MojoExecutionException - if we have a problem persisting the graph.
