---------------------------------------
Summary: Including the same XML rules file multiple times within
another XML rules file using <include url="classpath:<rulesFilePath> " />
causes DigeaterLoadingException (Circular file inclusion detected for XML rules)
Key: DIGESTER-198
URL: https://issues.apache.org/jira/browse/DIGESTER-198
Project: Commons Digester
Issue Type: Bug
Affects Versions: 3.2
Environment: OS: Windows 7, version 6.1, amt64
Java JDK 08.00.00-144_x64
Apache Maven 3.6.2
Reporter: Jochen Tümmers
Attachments: testApacheDigester3XmlIncludeRule.zip
When using the "same" XML include rule like
{code:java}
<include url="classpath:<rulesFilePath>" />{code}
multiple times within {*}another XML rules file{*}, Digester 3.2 fails with an
error message:
{code:java}
java.lang.Error: Loading runtime configuration failed
[org.apache.commons.digester3.binder.DigesterLoadingException: Digester
creation errors:1) Circular file inclusion detected for XML rules:
<rulesFilePath> (AbstractRulesModule.java:46)1 error]
{code}
even if there is no circurlar inclusion of XML rules file (XML rules file A
includes XML rules file B for procssing two different patterns the same way; no
additional includes for A in B).
Please see the test included in the attached Maven project.
A single XML rules file should be reusable for parsing different elements of an
XML file that have the same internal structure (see <element> and
<anotherElement> in configuration.xml that both contain the same structure (see
<parameters><parameter name="..." value="..." />...</parameters>)
Therefore, including an XML rules file multiple times within another XML rules
file for processing different patterns should be allowed as long as the
included XML rules file does not cause a (real) circular chain of inclusions.
