Evaluation error (NoSuchMethodError) in Azure ApplicationTokenCredentials when trying to start a VM

I have an Azure VM that I need to remotely control. I'm authenticating using ApplicationTokenCredentials in the expected way;
ApplicationTokenCredentials credentials = new ApplicationTokenCredentials(client,
tenant,
key,
AzureEnvironment.AZURE);
Then finding my machine:
VirtualMachine vm = Azure
.configure()
.withLogLevel(LogLevel.NONE)
.authenticate(credentials)
.withSubscription(subscription)
.virtualMachines()
.getByResourceGroup(resourceGroup, machineName);
This is essentially the same approach as the official documentation here shows;
https://learn.microsoft.com/en-us/azure/developer/java/sdk/java-sdk-manage-virtual-machines?view=azure-java-stable
This works, authenticates, and sets me up with a VirtualMachine object. I've confirmed that that's what it is and that it's the correct machine that I'm looking to control.
However when I try to start it with the start() method, this happens:
Evaluation error (NoSuchMethodError) at com.microsoft.azure.credentials.ApplicationTokenCredentials.getToken (ApplicationTokenCredentials.java:138).
My dependency tree looks fine. I'm using the newest version (1.35.0) of com.microsoft.azure (and only that) from maven central;
<dependency>
<groupId>com.microsoft.azure</groupId>
<artifactId>azure</artifactId>
<version>1.35.0</version>
</dependency>
Of course this is the parent dependency and it pulls down a bunch of artifacts. My dependency tree seems fine at a glance though:

At least I don't see anything that stands out as dependency conflict here. I really have no idea how to proceed here.

I ended up setting up a test project with just the VM management and found that working on the same dependencies.
After painstakingly comparing the dependencies between the two, I found one discrepancy; the version of the com.microsoft.azure.adal4j package was 1.6.4 on my test project, and 1.0.0 on my production app.
I have no idea how my production app ended up with an older version of this since all the root azure dependencies are identical, but I added this dependency to my production app, which fixed the issue:
<dependency>
<groupId>com.microsoft.azure</groupId>
<artifactId>adal4j</artifactId>
<version>1.6.4</version>
</dependency>

ElasticSearch : setup transport client

I'm new using ElasticSearch Java API, and i want to create the connection with my instance.
I followed the instructions here :
getting started
So i get the following code (as simple as on the exemple ! ) :
TransportClient mClient = new PreBuiltTransportClient(Settings.EMPTY)
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("host1"),
9300));
But I'm facing an issue about importing classes : TransportClient and Settings, that Eclipse cannot find...
Here is the maven import :
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>5.3.0</version>
</dependency>
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>transport</artifactId>
<version>5.3.0</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.7</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.7</version>
</dependency>
I tried to search bout this issue but didn't find the solution...
Eclipse found without any problem the PreBuiltTransportClient.
Here is the result of mvn dependency:tee

Any idea about what happens ?
I'm pretty sure that it's not a problem from maven configuration because I can import from elasticsearch some of classes needed...
Thanks in advance !

I am not an eclipse user for a few years now but this looks like an eclipse / maven configuration issue so I recommend you to review your eclipse configuration with maven.
I say this is a configuration issue because I have an application working with the following maven dependency configuration:
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>transport</artifactId>
<version>${elasticsearch.version}</version>
</dependency>
<!-- Log Dependencies required by elasticsearch 5 -->
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>${log4j.version}</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>${log4j.version}</version>
</dependency>
Notice that you don't need to add the org.elasticsearch (first one in your list) dependency as this was used when running elasticsearch embedded which is not supported anymore, but it's possible, if this is your case then leave it there, if you're just building a client you don't need that first dependency.
P.S - If your eclipse/maven configuration is correct then just maybe you forgot to mvn clean install before running your app?

Powermock - java.lang.IllegalStateException: Failed to transform class

Description:
I am trying to test a static method from a class. I am using powerMock (1.6.2) + mockito (1.10.19) for mocking along with Junit4 (4.12) & java8.
Issue:
Getting the error: "Failed to transform class with name com.gs.ops.domain.StaticClass Reason: java.io.IOException: invalid constant type: 18"
Solutions Tried:
Googled threads for issue on with powermock - mockito & java-8
Excluded java assist from powermock and added java assist 3.19.0-GA
Tried different versions of powermock (1.5.4, 1.6.2...)
Below is the exception stack trace:

Powermock 1.6.3 uses javassist 3.15.2-GA which does not support certain types. Using 3.18.2-GA javassist worked for me. You may want to override dependency in your project.
<dependency>
<groupId>org.javassist</groupId>
<artifactId>javassist</artifactId>
<version>3.18.2-GA</version>
</dependency>
You may face another problem for which the solution lies here Mockito + PowerMock LinkageError while mocking system class
Hope this helps.

So there seems to be issue with javassist (bytecode toolkit) prior to 3.18.2, as there's a resolved JIRA ticket-223.
1 - To find javassist version in your pom.xml, can use mvn dependency task
$ mvn dependency:tree | grep javassist
[INFO] | \- org.javassist:javassist:jar:3.14.0-GA:compile
which is used by the powermock-module-junit4-rule ,
[INFO] +- org.powermock:powermock-module-junit4-rule:jar:1.4.9:test
[INFO] | +- org.powermock:powermock-classloading-base:jar:1.4.9:test
[INFO] | \- org.powermock:powermock-core:jar:1.4.9:compile
[INFO] | \- org.javassist:javassist:jar:3.14.0-GA:compile
2 - So, updating the javassist version by explicitly to any versions >= 3.18.2 should work.
As, in my case, I am using use 3.20.0-GA
<dependency>
<groupId>org.javassist</groupId>
<artifactId>javassist</artifactId>
<version>3.20.0-GA</version>
</dependency>
Working eg. with scalatest
#PowerMockIgnore(Array("javax.management.*"))
#RunWith(classOf[PowerMockRunner])
#PrepareForTest(Array(classOf[Configurator]))
class LogServiceSpec {
#Test
def initialises_log4j2_on_each_instance_call() {
PowerMockito.mockStatic(classOf[Configurator])
val logService1 = new LogService
PowerMockito.verifyStatic(Mockito.times(1))
Configurator.initialize(Matchers.anyString(), Matchers.eq("log4j.config"))
}
}

This is caused because of the conflict of dependencies. Resolving the dependency conflicts is one way to resolve this issue and the other way is to reorder <dependency></dependency> elements in your pom.xml. Move the powermock dependency declarations to the top of the <dependencies></dependencies> section. This is a complete hack and the right way to resolve it would be to resolve the dependency conflicts.
To identify those conflict you may use the command "mvn dependency:tree". Here is the dependency tree for my application for which I came across this same problem. Notice that there are two dependencies of "javassist" in the tree.

I hope this helps.

In my case, a "java.io.IOException: invalid constant type: 18" was caused by multiple versions of javassist libraries in my classpath - both 3.12.1.GA and 3.18.2-GA. The problem disappeared when i removed the older one.

Not really an answer! I got a similar error when running a Maven build with JDK8 and generating Java6 byte code. My pom looks like this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<compilerVersion>1.6</compilerVersion>
<source>1.6</source>
<target>1.6</target>
<maxmem>2000m</maxmem>
<fork>true</fork>
</configuration>
</plugin>
When I reverted to JDK6 I no longer got the error.

In my case JRE System Library --> Execution Environment was set up on JavaSE-1.7, but the only installed JRE was JRE1.8. So it was pointing to java 8 in place of java 7. Once I moved to java 7 it start working fine for me.

This issue is related to a compatibility issue with Java 8. could you execute your tests on java 7 ?

Run "mvn dependency:tree | grep javassist" on terminal. If javaassist dependency is being shown in non test and test libraries. Now you only have to exclude it during runtime for tests. So the way to do this is adding a build plugin on the lines of:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.9</version>
<configuration>
<classpathDependencyExcludes>
<classpathDependencyExcludes>javassist:javassist</classpathDependencyExcludes>
</classpathDependencyExcludes>
</configuration>
</plugin>
</plugins>
Please note the classpathDependencyExcludes might change for you based on your javassist version.

My local environment: OSX 10.9.2, java1.6
I use java api to connect hbase and maven to manage my project, I added Hbase-0.94.17 and Hadoop-core-1.0.4 into pom.xml, when I ran my .java program to connect Hbase I got the following error:

Have slf4j-api and choose a SLF4J binding of corresponding version, and add them as dependencies in your own POM. It is quite possibly some of your dependencies transitively resolve an incompatible version of SLF4J binding which caused the problem. Find which library is bringing in the unwanted SLF4J binding (you can easily do so by mvn dependency:tree), and add corresponding exclusion in your dependency to that lib.
(Normally SLF4J binding shouldn't be declared in library. It is in fact something wrong that you may want to report to the library developer once you found the actual cause)
Update
That's exactly what I am talking about:
From your dependency tree:
[INFO] +- org.geogit:geogit-core:jar:0.8-SNAPSHOT:compile
[INFO] | +- org.slf4j:slf4j-api:jar:1.7.5:compile
.....
[INFO] +- org.apache.hbase:hbase-client:jar:0.98.0-hadoop2:compile
.....
[INFO] | +- org.apache.zookeeper:zookeeper:jar:3.4.5:compile
[INFO] | | \- org.slf4j:slf4j-log4j12:jar:1.6.1:compile
You got slf4j-log4j12 binding from hbase-client, and that's version 1.6.1
However, slf4j-api you have in your project is version 1.7.5. They are not compatible.
Proper way to solve is:
Exclude slf4j-log4j12 from your dependency of hbase-client
Declare a compatible SLF4J binding in your own project
You should also report this as a bug to zookeeper/hbase developer as it is not appropriate for a library to include SLF4J binding as compile scope dependency.

Can I use only the Transcoder of the Batik library without all other Batik code and dependencies?

I am trying to use the Batik library source, I only want to use the transcoder to convert SVG files to PNG or JPEG only. The distribution version of the Batik Rasterizer is about 55k but when I export the jar file its 7 megs. Can I just use the transcoder and not all the jars in the library? I am loading the jar files in Coldfusion. would it make more sense to just use the distribution version?

If you use maven you could set some dependencies to <scope>provided</scope>
For example I could exlude these without problems, which saved me ca. 1.6MB:
<dependencies>
...
<dependency>
<groupId>batik</groupId>
<artifactId>batik-gui-util</artifactId>
<version>1.6-1</version>
<scope>provided</scope>
</dependency>
<dependency>

It seems that these are the biggest dependencies:

Not exactly sure what you want to accomplish, but ProGuard will let you filter classes in jars that aren't used by your code.
