I've been trying to get this working all day reading docs over and over and I don't know what I'm doing wrong. I'm using the cloud code plugin for intellij it then automatically adds the maven dependencies. I've been following this tutorial but when I import, all I get is this:
Please could someone tell me what i'm doing wrong. All I want to do is upload a text file to google cloud using Java.
You have not shared your pom file. Maybe your cloud code plugin is not adding the dependency automatically as claimed. Can you check the pom file and make sure that you have the following dependency
<dependency>
<groupId>com.google.cloud</groupId>
<artifactId>google-cloud-storage</artifactId>
<version>1.98.0</version>
</dependency>
I am trying to use the javaFXGL library. Which is the java gaming library. I am not sure how to use maven to download the library to eclipse. Does anyone know a step by step way to download this. I need to this get some example code running.
I would be easier to get the help if you add your code in the question along with the problems/errors you are facing. Anyways I would suggest you to first read this and this to understand what is maven and how it works with Eclipse IDE.
After reading the articles you will understand that maven project has pom.xml file which is used for maven settings or you can say for Dependency Management, Build Management, etc.
To add the library you need to add its maven dependency in the pom.xml inside the <dependencies> tag like below:
<!-- https://mvnrepository.com/artifact/com.github.almasb/fxgl -->
<dependency>
<groupId>com.github.almasb</groupId>
<artifactId>fxgl</artifactId>
<version>0.2.9</version>
</dependency>
You can also find other dependencies on www.mvnrepository.com
I have visited the following link:
https://github.com/ReactiveX/RxJava/wiki/Getting-Started
and have tried to get RxJava to work with Eclipse, however even after importing it using Maven it still won't find the Observer and Subscriber objects when trying to import them.
I am not too sure where to go from here as the getting started link doesn't explain it that thoroughly.
I am also learning RxJava now, here is the necessary jar files you need:
If using Maven, add this dependency into pom:xml (replace with latest version available):
<dependency>
<groupId>io.reactivex</groupId>
<artifactId>rxjava</artifactId>
<version>1.0.11</version>
</dependency>
If you don't want to use Maven, I recommend you download the JAR file from Maven Repository:
http://mvnrepository.com/artifact/io.reactivex/rxjava

Refer to Is there a Java interface to Cassandra database that works out of the box? for my original issue.
I determined that the cassandra thrift API jar file I downloade was incomplete or out of sync with the Hector API. Where can I download it? I haven't been able to find a download for it from the official site.
The Maven repository are always a good choice for precompiled libs:
http://mvnrepository.com/artifact/org.apache.cassandra/cassandra-thrift
It also lists all dependencies. You could also use a Maven file (or another compatible build system) to download the lib with all it's dependencies automatically.
As far as I know there isn't an official jar that you can download. But you can grab the source-code here and compile it yourself:
http://thrift.apache.org/download/
If you use maven then you can just include the following in your pom:
<dependency>
<groupId>org.apache.thrift</groupId>
<artifactId>libthrift</artifactId>
<version>x.y.z</version>
</dependency>
If you download one of the release tgz files from https://github.com/rantav/hector/downloads it has the correct cassandra thrift to match the version of hector.
Iam trying to implement JMS using eclipse.But when I tried to save the code, it showed that javax.jms.* cannot be resolved and there are no suggestions as well recommended by it.
How can I include it and use it? when I googled I found that javax.jms.* is not a part of java API,then how can I use it in eclipse and get my program run successfully?
I would like to implement JMS with the help of activemq,what all do I need to download and include in code?
Iam a newbie to this JMS, please suggest some references or sample code that can implement JMS using activemq.
When you download the activemq archive file from Internet. Extract this archive: /apache-activemq-x.x.x
cd into this apache... directory.
You will see activemq-all-x.x.x jar file.
Include this in your build path.
This should resolve your issue.
If it is a maven project, add the following dependency to your pom.xml and it should start working as expected.
<dependency>
<groupId>javax.jms</groupId>
<artifactId>jms</artifactId>
<version>1.1</version>
</dependency>
There are actually many ways to fix this. As already stated in the comment you need the Java Enterprise Edition API. Java EE is an abstract specification so what you need is an implementation of the JMS API. Since JMS is part of the Java EE specification the easiest thing is to download a application server such as GlassFish (which is the reference implementation) or JBoss.
I assume you already got the Java compiler so you only need the SDK, not the JDK.
Java EE 6 SDK Update 4 A free integrated development kit used to
build, test, and deploy Java EE 6 applications.
http://www.oracle.com/technetwork/java/javaee/downloads/index.html
Then after you have downloaded GlassFish you will end up with a lot of files that is an implementation of the different Java EE specification API's. You will probably want to download the plugin that I linked to beneath so that you can start, deploy and do many other administration task of your server from Eclipse. I do not use Eclipse so I don't remember if you want this version of Eclipse as well.
http://marketplace.eclipse.org/node/867
At last you want to add GlassFish to your buildpath.
I found this blog post (Scroll to "Create projects in Eclipse") if you are unsure what to add, but there are several blog posts on how to add GlassFish to the build path in Eclipse so I won't list them here.

In addition to the answers already provided, if you are using Maven you can add the following dependency (available from Maven2 Central repo):
<dependency>
<groupId>javax.jms</groupId>
<artifactId>jms</artifactId>
</dependency>
When you have downloaded activemq zip file from http://activemq.apache.org then when you extract it, head on to .jar file of activemq(This jar file is required). Now from Eclipse do as follows:
RightClick on Project and go to Properties
Java Build Path tab
Libraries tab
Add External JARs...
Get that .jar file from activemq folder
I fixed this problem by including the dependency of Activemq.
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-all</artifactId>
<version>5.15.0</version>
</dependency>
It can be found in jboss-jms-api.jar
If you are using/Testing ActiveMQ.
Then configure your build path and add external jar activemq-all-.jar. (Path:In )
Clean and Build.
This will helped me , will do same to you as well.
Danke,
Rahul.
If you want to resolve this issue using maven, then the correct maven dependency, available in maven repository, is the following:
<dependency>
<groupId>javax.jms</groupId>
<artifactId>jms-api</artifactId>
<version>1.1-rev-1</version>
</dependency>
See post: The following artifacts could not be resolved: javax.jms:jms:jar:1.1
