I have faced the same problem. Resolved shifting JRE to JDK . First point is, in your environment setting make sure your are pointing JDK. For me even after changing environment variable again raised with the same problem. Which means Mule studio is still pointing the JRE. Next step : In mule studio, go to `windows->preference->InstalledJREs` change the JRE to JDK. This worked for me. Make sure these two points are done from your end. — star, Nov 09 '15 at 20:19
Do you get the same error message if you run mvn studio:studio from the root directory of the project on the command line? — Ryan Hoegg, Nov 12 '15 at 03:45

I solved the problem, I don't know exactly what has worked but I changed the java version and for every project I execute the following commands:

mvn clean install
mvn eclipse:eclipse

and then i refresh my project This can help: http://www.avajava.com/tutorials/lessons/how-do-i-update-my-maven-project-to-work-in-eclipse.html

I have faced same issue and got resolved by changing the JRE to JDK in preferences and restarted the any point studio. This resolved the issue to me.

I was getting the same error and I solved it by not just adding JDK in the installed JREs but setting Execution environment of JAVASE-1.8 to jdk1.8 and it worked. enter image description here

Check whether your MuleStudio.ini contains the configration for the correct path of your JDK:

-vm
C:\Path\To\Your\JDK\bin\javaw

I think the `-vm` argument has to be above `-vmargs` (the lines below are passed to the vm executable). – Jens Piegsa Nov 09 '15 at 17:58
the docs (https://docs.mulesoft.com/release-notes/anypoint-studio-march-2015-with-3.6.1-runtime-release-notes#hardware-and-software-system-requirements) say JDK 8 is not supported yet, maybe this is still the case ... – Jens Piegsa Nov 09 '15 at 20:02
I've tried java 6 and then i get the error that my anypoit studio required using more than the version 6 then i used java 7 and still have the same problem – Rajeun Nov 09 '15 at 21:58

You need to add the Maven Dependency for the Plugin

Step 1: Edit settings.xml to add a new profile with the following repositories and pluginRepositories. (There are two locations where a settings.xml file may live: $M2_HOME/conf/settings.xml or ${user.home}/.m2/settings.xml)

<profiles>
     ...
     <profile>
        <id>mule-extra-repos</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <repositories>
            <repository>
                <id>mule-public</id>
                <url> https://repository.mulesoft.org/nexus/content/repositories/public </url>
            </repository>
        </repositories>
        <pluginRepositories>
            <pluginRepository>
                <id>mule-public</id>
                <url> https://repository.mulesoft.org/nexus/content/repositories/public </url>
            </pluginRepository>
        </pluginRepositories>
     </profile>
     ...
 </profiles>

Step 2: Add a new pluginGroup, as shown below.

<pluginGroups>
    ...
    <pluginGroup>org.mule.tools</pluginGroup>
    ...
 </pluginGroups>

I think that is problem with your mule studio Java setting. Mule studio by default points JRE not JDK. tools.jar is available under JDK folder. See the below link which tell you how to add JDK to studio then use that to build

I noticed that if your flow involves API Kit and Dataweave, additional dependencies need to be added.

        <plugin>
            <executions>
                <execution>
                    <configuration>
                        <resources>
                            <resource>
                                <directory>src/main/api/</directory>
                            </resource>
                        </resources>
                    </configuration>
                </execution>
            </executions>
        </plugin>

and

    <dependency>
        <groupId>org.mule.modules</groupId>
        <artifactId>mule-module-apikit</artifactId>
        <version>${mule.version}</version>

If you are facing with below error from Anypoint studio when building project with Maven.

[ERROR] [ERROR] Some problems were encountered while processing the POMs:

Please follow the below steps to resolve the issue

From Anypoint studio goto Windows -> Preferences -> Installed JREs.
Here change the JRE (C:\Program Files\Java\jre1.8.0_162) to your JDK (C:\Program Files\Java\jdk1.8.0_162) and select the JDK checkbox and click Finish -> ok -> ok.

Now try to update the pom.xml file by Right clicking the pom.xml file Mule -> Update project dependencies.

If still you are facing the issue follow the another step as below:

Goto Windows -> preferences -> Installed JREs -> Execution Environment Here select JavaSE-1.8 and on right window click on the jdk1.8.0_162 [perfect match] and now try to Update project dependencies.

This will solve the issue.
