I'm following up on an issue which was fixed in SCDF as part milestone 107. Here is the Link. Any idea when the release version or Snapshots would be available with the above milestone ?
If there're any can I get Custom Build for that version to deploy in Kubernetes? I tried with changing the release version to 2.6.1.Snapshot ,but I'm getting unresolved dependency issues.

Here is my application.properties file
Tried using postgresql version 42.2.12 but no luck.
Here is error log screenshot.
May be this doesn't make sense but I had same problem and it was fixed with this 2 lines:
spring.jpa.hibernate.ddl-auto=create
logging.level.org.hibernate.SQL=debug
I launch Spring cloud data flow with docker-compose base on this website.
https://dataflow.spring.io/docs/installation/local/docker/
I created 3 apps, Source, Processor & Sink.
I ran
export STREAM_APPS_URI=https://dataflow.spring.io/Einstein-BUILD-SNAPSHOT-stream-applications-kafka-maven
When I run docker-compose -f ./docker-compose.yml -f ./docker-compose-prometheus.yml up, all my containers start up as specified in the docker-compose.yml and docker-compose-prometheus.yml.
I proceed to register the 3 applications and then create a stream with them.I then run it.
Question 1:
The status of the stream is always "Deploying". Shouldn't it be Deployed?
Question 2:
When I click on the "Grafana" icon, it launches the Grafana page but there is no data on it. Why is it so? I am using kafka as my messaging middleware as shown below.

I have a project A that where i created a folder called lib to add libraries in it. Currently i have Ojdb7.jar in this folder. Now, When I add the dependency for ojdbc7 in the POM file I get error "Missing artifacts".
I know there is an option to install it using :
$ mvn install:install-file -Dfile={Path/to/your/ojdbc7.jar}
-DgroupId=com.oracle -DartifactId=ojdbc7 -Dversion=12.1.0 -Dpackaging=jar
and it works fine when I run the command but What I want to do is to run mvn package command from cmd (mvn packge will run install before packaging the project to jar file). I tried the pom file below but i get error could not find artifact for the path I specified in repository tag

but my issue is that i don't want to hard code this path ${project.basedir}/ojdbc7.jar
Because I run this in Jenkins and it failed. Any help is much appreciated.
Thanks
**Adding screen shot
Here another shot from eclipse Problems:
I have a Maven project, I added vaadin-push as dependency in the pom.xml.
The first problem is in the MainUI class, when I add the annotation #Push(PushMode.MANUAL) it doesn't recognize the PushMode so I am stuck with #Push. When I add it, i get the error message when I access the UI:
{"timestamp":1519112562626,"status":500,"error":"Internal Server Error","exception":"com.vaadin.server.ServiceException","message":"java.lang.IllegalStateException: Push is not available. See previous log messages for more information.","path":"/bp/list"}
I tried to follow the instructions on vaadin website on push so I added a web.xml (I didnt have one previously). I'm not sure whether it is being used. I would prefer to configure this solely by annotations.
<?xml version="1.0" encoding="UTF-8"?>
<web-app
id="WebApp_ID" version="3.0"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<param-name>pushmode</param-name>
<param-value>automatic</param-value>
</init-param>

</servlet>
</web-app>
What I actually want to achieve is to update the UI on a Rest request, I think the Rest part already works apart from the Push:
public class UILister {
private static HashMap<UUID,MainUI> uiByUuid = new HashMap<UUID,MainUI>();
public static void closeUIConnectorFrame(UUID uuid) {
MainUI ui = uiByUuid.get(uuid);
if(ui != null) {
ui.access(new Runnable() {
#Override
public void run() {
ui.closeConnectorFrame();
ui.push();
}}
);
}
}
public static void addUI(UUID uuid, MainUI mainUI) {
uiByUuid.put(uuid, mainUI);
}
}
pom.xml. I removed the vaadin-push since it tells me I am overriding the one configured automatically.

In your pom, add
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-push</artifactId>
</dependency>
You don't need to specify a <version> here, since the version is managed by vaadin-bom (bill of materials) which declares the correct version for each artifact (so that it is easier to avoid conflicting dependencies to different versions of the same framework), but importing the BOM doesn't add the dependencies by itself.
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-bom</artifactId>
<version>${vaadin.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
I removed the vaadin-push since it tells me I am overriding the one configured automatically.
The one configured automatically refers to the version managed by the BOM. For instance, when one adds a dependency to vaadin-push with a <version> tag, Eclipse it gives the following warning:
Overriding managed version 8.1.1 for vaadin-push
I have an spring boot app that leverage the java 8 and have used hibernate 4 so far. I needed however to change part of my model to include the new ZonedDateTime class provided by java8 i.e. I needed a datatime type that provide me the instance of time in utc together with the offset and the time zone. For that reason i wanted to have the native hibernate 5 support. I have replaced in my pom the the parts:
//<dependency>
// <groupId>org.hibernate</groupId>
// <artifactId>hibernate-core</artifactId>
// <version>4.3.10.Final</version>
//</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-java8</artifactId>
<version>5.0.0.CR2</version>
</dependency>
and i have changed in my SpringPercisence confguration class to use the hibernate 5 instead of hibernate 4 i.e.
#Bean
public org.springframework.orm.hibernate5.LocalSessionFactoryBean sessionFactory() {
// org.springframework.orm.hibernate4.LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
org.springframework.orm.hibernate5.LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
sessionFactory.setDataSource(this.dataSource());
sessionFactory.setPackagesToScan("org.test");
sessionFactory.setHibernateProperties(hibernateProperties());
return sessionFactory;
}
#Bean
// public org.springframework.orm.hibernate4.HibernateTransactionManager transactionManager() {
public org.springframework.orm.hibernate5.HibernateTransactionManager transactionManager() {
HibernateTransactionManager txManager = new HibernateTransactionManager();
txManager.setSessionFactory(sessionFactory().getObject());
return txManager;
}
#Bean
public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
return new PersistenceExceptionTranslationPostProcessor();
}
#Bean
public Properties hibernateProperties() {
return new Properties() {
{
setProperty("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");
setProperty("hibernate.chach.provider_class", "org.hibernate.cache.NoCacheProvider");
setProperty("hibernate.show_sql", "true");
// setProperty("hibernate.hbm2ddl.auto", "create");
setProperty("hibernate.hbm2ddl.auto", "create-drop");
// setProperty("hibernate.hbm2ddl.auto", "update");
}
};
}
I am getting an error that is somehow related to the "sessionFactory" bean that configured above, and later it says something about ImplicitNamingStrategy. I have read here
http://in.relation.to/2015/03/31/hibernate-orm-500-beta-1-release/
that hibernate NamingStrategy has been removed but i do not understand what exactlly that mean. Since i was not able to find an example of hibernat and spring4 i hope that someone could help me out here with this one.

Your pom is containing a lot of clutter and working around Spring Boot defaults. I suggest using the correct starters and not add the dependencies again. Also instead of using java-version use java.version this will set the correct version for Spring Boot also and thus you could remove the compiler plugin.
Also support for Hibernate 5 CR2 has been added to Spring 4.2 in the latest release candidate of Spring 4.2 (RC3). So I suggest using that instead of the one you are using now. Also I suggest specifying the hibernate.version as a property to trigger Spring Boot to include the correct version.
All this leads to the following pom (did a bit of cleanup and moving things around to my personal preference).
