• IGNORE_INDEX

  public static final String IGNORE_INDEX

  System property that instructs Spring to ignore the index, i.e. to always return null from loadIndex(ClassLoader).

  The default is "false", allowing for regular use of the index. Switching this flag to true fulfills a corner case scenario when an index is partially available for some libraries (or use cases) but couldn't be built for the whole application. In this case, the application context fallbacks to a regular classpath arrangement (i.e. as no index was present at all).
