I have added dependency guava for using Multimaps and also I have added Hive dependency in my project.
I am getting the following error while compiling application.
An attempt was made to call the method com.google.common.collect.Multimaps.asMap(Lcom/google/common/collect/ListMultimap;)Ljava/util/Map; but it does not exist. Its class, com.google.common.collect.Multimaps, is available from the following locations:
jar:file:/Users/sreenivas/.m2/repository/org/apache/hive/hive-exec/1.2.1/hive-exec-1.2.1.jar!/com/google/common/collect/Multimaps.class
jar:file:/Users/sreenivas/.m2/repository/com/google/guava/guava/25.1-jre/guava-25.1-jre.jar!/com/google/common/collect/Multimaps.class
It was loaded from the following location:
file:/Users/sreenivas/.m2/repository/org/apache/hive/hive-exec/1.2.1/hive-exec-1.2.1.jar
Action:
Correct the classpath of your application so that it contains a single, compatible version of com.google.common.collect.Multimaps.
Can anyone suggest me how to take the latest version dependency.
It is caused by the package hive-exec include /com/google/common/collect/Multimaps.class, as shown in picture:
If you have to include these two jar (hive-exec-1.2.1.jar and guava-25.1-jre.jar), you'd better fix hive-exec's source code and repackage it.

I'm using just the one dependency and cant see any conflicts.

Help me!
Please check maven dependency::tree, it must be some jar package(spring core with difference version) conflict.
Can I not use the following Gradle approach to dependencies in Grails? I do not have nor want a parent directory;
https://stackoverflow.com/a/19303545/2288004
When I try it, I get the the following error;
Caused by: java.lang.IllegalStateException: Expected method not found:
java.lang.NoSuchMethodException:
org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedContext.addApplicationListener(org.apache.catalina.deploy.ApplicationListener)
It works when I use a parent directory for the settings.gradle, but unfortunately it’s not how I want to structure the project.
The following was indeed the solution I was looking for,
include ":myplugin"
project(':myplugin').projectDir = new File(settingsDir, '../myplugin')
The error was down to how I was managing my tomcat dependencies between the two projects.
Tomcat was already being pulled in via the plugin but while I still needed to reference tomcat at compile time in the application, I also needed to make sure it was the same version, and so added the following just above "dependencies" to target the version I required;
ext['tomcat.version'] = '7.0.70'
I am trying to add bouncy castle as a service provider to my java product running on apache karaf.
When I am trying to start the bundle which imports bouncy castle I get an error message
java.lang.Exception: Could not start bundle mvn:com.xxx.yyy.zzz/docsservice/1.0.0-SNAPSHOT/war in feature(s) server-docs-1.0.0-SNAPSHOT: Unresolved constraint in bundle docs [245]: Unable to resolve 245.0: missing requirement [245.0] osgi.wiring.package; (&(osgi.wiring.package=org.bouncycastle.jce.provider)(version>=1.51.0))
at org.apache.karaf.features.internal.FeaturesServiceImpl.startBundle(FeaturesServiceImpl.java:472)
In the pom file I imported the package org.bouncycastle.jce.provider and I added bouncycastle as a dependency.
Also, i made all the changes described on this page,
http://karaf.apache.org/manual/latest/users-guide/security.html, see below
I put provider jar in lib/ext
I Modified the etc/config.properties configuration file to add the following property
org.apache.karaf.security.providers = xxx,yyy
org.apache.karaf.security.providers = org.bouncycastle.jce.provider.BouncyCastleProvider
I provided access to the classes from those providers from the system bundle so that all bundles can access those. I did this by modifying the org.osgi.framework.bootdelegation property in the same configuration file:
org.osgi.framework.bootdelegation = ...,org.bouncycastle*
On some forum I found another suggestion so I modified
*org.osgi.framework.system.packages.extra = * in the config.properties as well and I added here packages exported from bouncycastle
Nonetheless I wasn't able to load the bundle successfully. I looked at all the bundles loaded by karaf and none of them was exporting bouncy castle package.
What am I missing here? How can I make the bundles to start?
By adding the package to the boot delegation you made it available like java.* packages. For these you do not need an Import-Package. So one way would be to remove the Import-Package for it in your bundle. You should rather explore though if you can work without boot delegation.
Please try to remove the boot delegation and add the package to
org.osgi.framework.system.packages.extra = org.bouncycastle.jce.provider
This adds the package to the packages the system bundle exports. It should then be wired to your bundle.
I'm using the HotSwap function of javassist, it requires tools.jar in classpath, so I added -cp tools.jar when start my OSGi appliction. But when I new HotSwap() in the code of one of the bundles,
java.lang.NoClassDefFoundError: com.sun.jdi.Bootstrap
was thrown. com.sun.jdi.Bootstrap is in the tools.jar and I've already added it in classpath and also I verified it worked because if not, the following code will not work:
JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
The Classloader of HotSwapper cannot load classcom.sun.jdi.Bootstrap? Then why it works properly in my Eclipse environment?(I added tools.jar into the libraries of Build path)
On why NoClassDefFoundError, any clue is appreciated.
You have to make sure the system bundle exports this package. For example in Felix the file jre.properties defines what packages are exported by the system bundle. Add the package com.sun.jdi there and it should work.
In eclipse this is done in config.ini. You can use org.osgi.framework.system.packages.extra= to define additional packages to export. I would rather not use boodelegation=* as it might export unwanted packages too. See:
http://www.eclipse.org/forums/index.php/m/734358/
http://wiki.eclipse.org/Equinox_Boot_Delegation
In Equinox, you can set Boot Delegation to * to gain acess to all class in bootclass, see this wiki for details. In 3.2, it was osgi.compatibility.bootdelegation=true in config.ini.
