We have a spring-boot project and configure the logback-spring.xml as below
<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="true">
<include resource="org/springframework/boot/logging/logback/base.xml" />
<define name="INCLUDED_FILE_EXISTS"
class=" ch.qos.logback.core.property.FileExistsPropertyDefiner">
<path>application.properties</path>
</define>
<if condition='property("INCLUDED_FILE_EXISTS").equals("true")'>
<then>
<property resource="application.properties" />
</then>
</if>
<property resource = "config/application.properties" />
...
</configuration>
Since there will have different properties in different modes (e.g., dev or production), we want to conditional processing the property resource as above configuration. If the application.properties file is existed then it will be loaded in, whereas config/application.properties will always be loaded-in.
However, we got the following error when boot-up:

The logback we used is 1.1.3 from spring-boot-starter-logging 1.3.1-RELEASE and the janino lib for conditional processing we used is 2.7.8. We didn't declare the version of janino, but it goes to v2.7.8 which I didn't know why.
<dependency>
<groupId>org.codehaus.janino</groupId>
<artifactId>janino</artifactId>
</dependency>
Are there has anything we miss? Any help is appreciated.
You have a misplaced space character between the double quote " and the package name:
class=" ch.qos.logback.core.property.FileExistsPropertyDefiner"
Should be:
class="ch.qos.logback.core.property.FileExistsPropertyDefiner"
