intellij tomcat "copying resources" takes too much time

I'm building a basic web app using JSF and spring using IntelliJ IDEA. So I followed this post to config the IDEA with tomcat. But when I run the app, it takes too much time to build saying coping resources.(like 1/2 an hour) And when I make a change it takes much longer time. Strangest thing is, after the build, there are ~2GB files inside the target folder. And the same classes folders are recursively copied in to it. which means target\classes\classes\artifacts\java_test_war_exploded\WEB-INF\classes\target\classes\target\classes\target\m2e-wtp\web-resources\META-INF\maven\java_test\...etc. This goes to like infinity!
What is the problem here? Please someone help!
(sorry for my English)

I still couldn’t find a solution for this. So I just deleted the .idea directory from the project and reimported the project to IntelliJ. Then it worked!

I have faced this problem. At first check your project folder's size. If it is too large and it is not normal (my target folder was more than ~ 2 GB) , we have a same problem!
My mistake which caused this problem was that in intellij idea, I had refactored so many packages and changed folder's directions so many at the beginning of my project. My IDE confused and made a lot of same folders in each folder and continued it many many times! Like taking selfie in front of a mirror! what will happen to your pic? it will repeat infinitely.
my solution: create my project again as same as the previous one. but by taking care and not refactoring!
Just this!

I have tried many site available on but not able to resolve
Can anyone help me with the pom.xml for spring boot that support java 1.6?

By default, Spring Boot 1.4.4.RELEASE requires Java 7 and Spring Framework 4.3.6.RELEASE or above. You can use Spring Boot with Java 6 with some additional configuration. See Section 81.11, “How to use Java 6” for more details. Explicit build support is provided for Maven (3.2+) and Gradle (1.12 or 2.x). Support for Gradle 2.8 and earlier is deprecated. Gradle 3 is not supported.
See the link
https://docs.spring.io/spring-boot/docs/current/reference/html/getting-started-system-requirements.html

Above answer is help but i want to add detailed changes that i made in my pom.xml to resolve my issue.
We just need to exclude jackson jar from dependency and in properties we have to set java version to 1.6.
Please refer my pom.xml to run spring boot in java 1.6.

The thing is that I know where the issue is coming from. It's from my Behave dependency in the pom file. I tested it by commenting it out and it then runs. Here is my pom file so you can look at it.

The reason for your issue is that JBehave as a dependency on FreeMarker (see deps on mvnrepository.com) which causes Spring Boots auto configuration to kick in and configure FreeMarker as your template engine. Basically you do have different options to get rid of this issue
Do what the error states and add spring.freemarker.checkTemplateLocation=false to your application.yml or application.properties to suppress the check for templates location. This still leaves you with the template engine configured
Disable Autoconfiguration for FreeMarker by adding the exclude option to your #SpringBootApplication like this #SpringBootApplication(exclude={FreeMarkerAutoconfiguration.class})
Create the templates folder as expected in resources.
Exclude the transient dependency on your JBehave dependency in your pom.xml as described in the documentation of Maven.
Which of those is the right decision depends on your demand and the application, e.g. if you do not need JBehave's HTML or Mail reporting functionality which uses FreeMarker it is most likely safe to go for option 4, in all other cases I personally would use option 2.
Side notes
You should always scope your dependencies properly, e.g. all of your deps for testing should correctly have a <scope>test</scope> setting as it is the case for the spring-boot-starter-test. That helps to keep the final artifact small.
I don't see a reason for what you'd need the scala dependency in your setup.
logback is the default logging framework in Spring Boot and does not have to be defined. I'm actually also not 100% sure if it is a really good idea to have two logging libs (log4j and logback) in your setup.
Is there a special reason why you not used spring-social-facebook but rather restfb instead? Does not look consistent to me.
Additionally I'm wondering about having spring-data-jpa dependency in as well as the plain spring-boot-starter-jdbc?
In general you defined a lot of your dependency explicitly whereas they are anyhow provided as a transient dependency of other requirements, e.g. hibernate would be automatically brought in by spring-data-jpa.
I personally would go for version 1.3.2 of spring-boot in your parent relationship definition. It will bring in a lot of new functionalities and should be really non-breaking.

Changing Dynamic Web Module version in Eclipse Maven Project

I'm trying to set up Dynamic Web Module 3.0 in order to support Java 6 development. I'm getting this error in my Problems tab of eclipse whenever I do Maven > Update Project.
Dynamic Web Module 3.1 requires Java 1.7 or newer.
It appears as though nothing is going wrong, but I must be missing something because I consistently receive this error.
Below is the contents of my .settings/org.eclipse.wst.common.project.facet.core.xml
<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
<fixed facet="jst.java"/>
<fixed facet="jst.web"/>
<installed facet="jst.java" version="1.6"/>
<installed facet="jst.web" version="3.0"/>
</faceted-project>
In eclipse, my Java Compiler is set to 1.6 properly. In the Project Facets tab, Dynamic Web Module is specified as version 3.0 correctly, and Java also appears as 1.6 under Project Facets.
In my pom.xml file, I have also set the Java version accordingly:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
As a side note, I should also mention that I am doing a pure-Java build with a WebApplicationInitializer and have no web.xml file.
Any help is greatly appreciated as I attempt to squash this seemingly irrelevant error message.

In an our project, we add to change the web.xml root element's declaration, changing from:
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
to:
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5" >
Probably Eclipse were expecting it as satisfying a different Servlet version spec. In our case too, we had neither compile nor runtime problems.
EDIT: In your case, where you were not using a web.xml file, there was the following pom's dependency which probably was confusing Eclipse's maven plugin:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
Change it to "3.0.1". (It turns out that WebApplicationInitializer requires "Servlet 3.0+ environments" and not 3.1+)

you can add this to the pom.xml:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
</plugins>
</build>
Works in Spring STS 3.6.3 :)

Try changing your JRE/JDK version to 1.7. The web project module doesn't support 1.6.

I can't find the dependency for com.google.api.client.util.Preconditions using Maven

I'm new with Google Calendar API. What I'm trying to do here is to post an Event to the Google Calendar with the e-mail given by the user. My problem now is, when I tried to do the configuration, I get this exception:
Caused by: java.lang.ClassNotFoundException: com.google.api.client.util.Preconditions
I have tried different versions of the google api but I can't find which jar contains this class. The part on my code that's causing this exception is this :
GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
httpTransport, jsonFactory, clientId, clientSecret,
Arrays.asList(CalendarScopes.CALENDAR)).setAccessType("online")
.setApprovalPrompt("auto").build();
Thanks in advance to anyone who will help.

It seems there is a conflict of versions between the modules google-api-client and google-http-client-jackson2. They must be of the same version 1.17.0-rc.
