SAXParseException when running the project with Spring Boot 1.4.0

[josephpford]

When running the project from the commandline, I encounter a SAXParseException. If I downgrade Spring Boot from 1.4.0 to 1.3.7, the problem goes away.

Steps to reproduce:
git clone https://github.com/spring-guides/gs-integration.git
cd gs-integration/complete
gradle wrapper
./gradlew build
java -jar build/libs/gs-integration-0.1.0.jar

Encounter Exception:

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 25 in XML document from class path resource [hello/integration.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 25; columnNumber: 59; cvc-complex-type.3.2.2: Attribute 'mode' is not allowed to appear in element 'file:outbound-channel-adapter'.

@artembilan @garyrussell Can either of you investigate?

[artembilan]

Will do right now.

[artembilan]

According to this: spring-projects/spring-boot@c068285

there is no spring-integration-file jar in the classpath:

BOOT-INF\lib\spring-integration-core-4.3.1.RELEASE.jar
BOOT-INF\lib\spring-integration-feed-4.3.1.RELEASE.jar
BOOT-INF\lib\spring-integration-java-dsl-1.1.3.RELEASE.jar
BOOT-INF\lib\spring-integration-jmx-4.3.1.RELEASE.jar

in contradistinction to this in case of Boot 1.3.x:

lib\spring-integration-core-4.2.9.RELEASE.jar
lib\spring-integration-feed-4.2.9.RELEASE.jar
lib\spring-integration-file-4.2.9.RELEASE.jar
lib\spring-integration-http-4.2.9.RELEASE.jar
lib\spring-integration-ip-4.2.9.RELEASE.jar
lib\spring-integration-stream-4.2.9.RELEASE.jar

So, gs-integration has to be fixed with extra dependency.

Will PR that soon.
