Since about a week ago, running tests with InProcessServer on 4.0.0.BUILD-SNAPSHOT results in the following exception:
Caused by: java.lang.NoClassDefFoundError: org/neo4j/ogm/testutil/TestServer
at org.springframework.data.neo4j.server.InProcessServer.<init>(InProcessServer.java:25) ~[spring-data-neo4j-4.0.0.BUILD-SNAPSHOT-tests.jar:na]
at com.ninjasquare.server.test.integration.IntegrationTestConfig.neo4jServer(IntegrationTestConfig.java:43) ~[test-classes/:na]
Swithing the test dependency back to 4.0.0.M1 resolves the issue:
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-neo4j</artifactId>
<version>4.0.0.M1</version>
<type>test-jar</type>
</dependency>
I assume it's something to do with some refactoring work on SDN4/OGM?
Thanks.
Yes, in recent snapshots, the OGM has been separated from SDN. You'll need to include these two dependencies now to use the test utilities.

Could someone point me to a possible solution? We're migrating a really old Struts2.3/Spring4/Hibernate4 application to Struts 2.5.30 / Hibernate 5.2.1 / Spring 5.2.21. Also, the legacy app had Tiles 2.2.2 which we haven't changed. We're keeping Tiles 2.2.2 as is.
<properties>
<log4j.version>2.17.2</log4j.version>
<java.version>11</java.version>
<finalName>oar</finalName>
<spring.version>5.2.21.RELEASE</spring.version>
<hibernate.version>5.2.1.Final</hibernate.version>
<struts.version>2.5.30</struts.version>
<tiles.version>2.2.2</tiles.version>
</properties>
With these Maven dependencies, when the app launches, I get the following error:
java.lang.AbstractMethodError: Receiver class org.apache.struts2.tiles.StrutsTilesInitializer

Per the Version Properties above, the relevant Struts & Tiles dependencies are below. Note that struts2-tiles-plugin is included, with the version as per the property, 2.5.30. (My understanding is that there's also a newer struts2-tiles3-plugin but I'm not using that, since our Tiles is kept at 2.2.2.) Could the problem actually be that we're keeping Tiles 2.2.2 which is incompatible with Struts 2.5.30? We don't want to switch to Tiles 3, because there are a lot of differences (e.g., useAttribute has changed).

The Struts 2 framework used a plugin for integration with Tiles framework. The plugin for Tiles 2 is struts2-tiles-plugin and for Tiles 3 is struts2-tiles3-plugin. You should not define the version of Tiles in your pom.xml because it is incurred from the transitive dependencies for each plugin. Look at this answer which has links to examples with the Tiles integration. Note how the version is defined
<struts2.version>6.0.0-RC3</struts2.version>
and
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-tiles-plugin</artifactId>
<version>${struts2.version}</version>
</dependency>
If you specify Tiles version separately in your configuration, it can be incompatible with one from the plugin dependencies and you have probably exlude it to resolve the error.
I'm trying to use an unmanaged extension which uses 2.1.2 neo4j.version
on a neo4j server (version CE 3.5.11 Cypher version: CYPHER 3.5).
The neo4j server starts properly but when I invoke the Rest Service provided by that unmanaged extension via Postman I get the following error
javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/neo4j/cypher/javacompat/ExecutionEngine
the extension is installed via the following pom :

locally the extension works well all unit tests succeed.
Thank you for your help.
You need to set <neo4j.version> to 3.5.11, to be compatible with the neo4j server version.
If necessary, you may also need to fix the extension so that it will build and work correctly, since version 2.1.2 is extremely old.
I am trying scdf and its monitoring with prometheus and grafana. I followed the documentation available and able to deploy the sample stream and able to see the metrics in the grafana.
I have created a stream with some custom stream app (other than the supplied rabbit mq starter apps).
Stream:
htt | participant | log
But am not able see the "participant" application metrics in gafana. But able to see the metrics of http and log apps.
Added below properties in application.properties.
management.endpoint.metrics.enabled=true
management.endpoints.web.exposure.include=*
management.endpoint.prometheus.enabled=true
management.metrics.export.prometheus.enabled=true
spring.cloud.streamapp.security.enabled=false
Added below dependencies:
<dependency>

After adding app-starters-common:org.springframework.cloud.stream.app dependency localhost:< port >/ opens a login page.
I think you need app-starters-micrometer-common dependency which adds some of the micrometer tags to your app. This dependency is intended to be used by the Spring cloud stream app starters and I believe you can use it in your custom application as well.
I came across this question while looking answers for the same.
Here is my working code snippet:-
Pom.xml
<dependency>
<groupId>org.springframework.cloud.stream.app</groupId>
<artifactId>app-starters-micrometer-common</artifactId>
<version>2.1.2.RELEASE</version>

<artifactId>micrometer-registry-prometheus</artifactId>
</dependency>
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-registry-jmx</artifactId>
</dependency>
application property change to enable prometheus and disable security(login page)
management.endpoints.web.exposure.include=*
management.metrics.export.prometheus.enabled=true
-- this one to remove security (login page), which was automatically added by app-starter-micrometre-common dependency.
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration, org.springframework.boot.actuate.autoconfigure.security.servlet.ManagementWebSecurityAutoConfiguration
or
exclude the dependency, I excluded config-client and few other since I don't need them in my application.
<dependency>
<groupId>org.springframework.cloud.stream.app</groupId>

With later Data Flow 2.3.x, you need to add the following dependencies to your processor:
<dependency>
<groupId>org.springframework.cloud.stream.app</groupId>
<artifactId>app-starters-micrometer-common</artifactId>
<version>2.1.2.RELEASE</version>
</dependency>
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-registry-prometheus</artifactId>
</dependency>
<dependency>
<groupId>io.micrometer.prometheus</groupId>
<artifactId>prometheus-rsocket-spring</artifactId>
<version>0.9.0</version>
</dependency>
The app-starters-micrometer-common injects DataFlow specific tags, such as stream.name, application.name, application.type all used by the dashboard to aggregate the required metrics.
In addition you can follow instructions in the sample projects, showing how to build custom Source, Processor and Sink apps with enabled prometheus monitoring:

The neo4j-ogm version is really old- can you change that to 1.1.3?
You also should not need a dependency on neo4j-io
