static List<String>	extractJvmArgs(Map<String,String> runParameters)
static String	findJavaExecutable(String explicitlyDefinedJavaHome, Map<String,String> propsAndVars, String baseDir)	Finds Java executable (java.exe) using the specified parameters: - explicitly defined path - map of properties and environment variables (with corresponding prefixes) If found path is relative, it will be resolved against base dir.

Returns "default" set of system properties for the java process being launched

Parameters:

build - agent running build

runnerContext - runner context

Returns:

Map with the properties

findJavaExecutable

@Nullable
public static String findJavaExecutable(@Nullable
                                        String explicitlyDefinedJavaHome,
                                        @NotNull
                                        Map<String,String> propsAndVars,
                                        @Nullable
                                        String baseDir)

Finds Java executable (java.exe) using the specified parameters: - explicitly defined path - map of properties and environment variables (with corresponding prefixes) If found path is relative, it will be resolved against base dir.

Parameters:

explicitlyDefinedJavaHome - explicitly defined path

propsAndVars - map of properties and environment variables (with corresponding prefixes)

baseDir - base directory to be used for relative path

Returns:

path to existing java executable or null

findJavaExecutablePath

@Nullable
public static File findJavaExecutablePath(@Nullable
                                          String explicitlyDefinedJavaHome,
                                          @NotNull
                                          Map<String,String> propsAndVars,
                                          @Nullable
                                          String baseDir)

Finds Java executable (java.exe) using the specified parameters: - explicitly defined path - map of properties and environment variables (with corresponding prefixes) If found path is relative, it will be resolved against base dir. No file existence checks are performed. Path will end with 'java.exe' in windows and with 'java' on all other OSes.

Parameters:

explicitlyDefinedJavaHome - explicitly defined path

propsAndVars - map of properties and environment variables (with corresponding prefixes)

baseDir - base directory to be used for relative path

Returns:

found and possible resolved absolute path to java executable, null is returned is no candidate paths are found at all

findJavaHome

@Nullable
public static String findJavaHome(@Nullable
                                  String explicitlyDefinedJavaHome,
                                  @NotNull
                                  Map<String,String> propsAndVars,
                                  @Nullable
                                  String baseDir)

Finds Java home - path to a directory where Java is installed.

Parameters:

explicitlyDefinedJavaHome - explicitly defined path

propsAndVars - map of properties and environment variables (with corresponding prefixes)

baseDir - base directory to be used for relative path

Returns:

Java home - path to a directory where Java is installed
