getExpectedVersionOfDependencyByProperties

protected String getExpectedVersionOfDependencyByProperties(Class<?> dependerClass,
                                                            String propertiesFileName,
                                                            String dependencyNameAsKey)

checkForVersionEquality

public static void checkForVersionEquality(Context context,
                                           String dependerVersion,
                                           String dependencyVersion,
                                           String dependerName,
                                           String dependencyName)

Compares the versions of a depender and a dependency to determine if they are equal. Updates the context's status manager with version information and logs a warning if the versions differ.

Since:

1.5.26

addFoundVersionStatus

protected static void addFoundVersionStatus(Context context,
                                            String name,
                                            String version)

nameToPropertiesFilename

protected static String nameToPropertiesFilename(String name)

compareExpectedAndFoundVersion

public void compareExpectedAndFoundVersion(String actualDependencyVersion,
                                           Class<?> dependerClass,
                                           String dependerVersion,
                                           String dependerName,
                                           String dependencyName)

Compares the expected version of a dependency with the actual version found and updates the status context. If the versions do not match, a warning is added to the context's status manager.

Note: This method is used be logback-access-jetty11/12 and logback-access-tomcat.
