Usually  define maven-compiler-plugin is sufficient enough  add the following to your compiler plugin definition    lt plugin gt       lt inherited gt true lt  inherited gt       lt groupId gt org apache maven plugins lt  groupId gt       lt artifactId gt maven-compiler-plugin lt  artifactId gt                 lt  plugin gt

We tried everything listed so far and it still failed. The error also mentioned

(default-war) on project utilsJava: Error assembling WAR: webxml attribute is required

The solution that finally fixed it was adding this to POM:

<failOnMissingWebXml>false</failOnMissingWebXml>

As mentioned here Error assembling WAR - webxml attribute is required

Our POM now contains this:

<plugin>
<inherited>true</inherited>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>${maven-war-plugin.version}</version>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
<warName>${project.artifactId}</warName>
<attachClasses>true</attachClasses>
</configuration>
</plugin>

None of the other answers suggests downloading just the missing plugin.

Before you delete your whole .m2 repository and re-download all project dependencies and all plugins, you may want to try:

mvn dependency:resolve-plugins

That will download just the missing plugins.

i had the same problem and besides the above posts' configurations putting

            <plugin>
            <groupId>com.google.appengine</groupId>
            <artifactId>appengine-maven-plugin</artifactId>
            <version>1.9.32</version>
            <configuration>
                <enableJarClasses>false</enableJarClasses>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>endpoints_get_discovery_doc</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

in the plugins element in pom.xml. i think the problem was absence of execution -> goal "endpoints_get_discovery_doc" in some cases like mine, so this worked for me.

check the  property endorsed dir tag in your pom xml  I also had this problem and I fixed by modifying the property     Example    lt endorsed dir gt   project build directory  endorsed lt  endorsed dir gt

It is because your Jenkins not able to find setting file. If deleting .m2 not work, try below solution

Go to your JOB configuration

than to the Build section

Add build step :- Invoke top level maven target and fill Maven version and Goal

than click on Advance button and mention settings file path as mention in image

I had this problem once  and this is how i resolved it   Step-1 Clean your  m2 repository   Step-2 execute the maven command for example mvn clean verify  from the terminal at the current project location where your project s pom xml file exist  instead of running maven from eclipse

Sometimes it is caused due to the project points to JRE rather than JDK.So try this,

1.Right Click on project -->Build Path --> Configure Build Path -->Add Library -->JRE System Library -->Environments--> Installed JREs-->Point to java folder in c: drive (Windows) and select JDK folder and ok.

2.Remove the already present JRE from build path.

It s really incredible to be oblige to erase whole  m2 repository content  I suggest to type this command  On Windows     mvn clean mvn -X package  gt  my log file log  The last command enable Debug option et redirect output to a file  Open the file and search ERROR or WARNING key words  You can find this kind of expression   DEBUG                                                                           WARNING  The POM for javax servlet javax servlet-api jar 4 0 0 is invalid  transitive dependencies  if any  will not be available  1 problem was encountered while building the effective model for javax servlet javax servlet-api 4 0 0  FATAL  Non-parseable POM C  Users vifie  m2 repository net java jvnet-parent 3 jvnet-parent-3 pom  processing instruction can not have PITarget with reserved xml name  position  END TAG seen     lt  profiles gt  n n lt  project gt  n n lt  xml      160 7     C  Users vifie  m2 repository net java jvnet-parent 3 jvnet-parent-3 pom  line 160  column 7   WARNING  The POM for org glassfish javax json jar 1 0 4 is invalid  transitive dependencies  if any  will not be available  1 problem was encountered while building the effective model for org glassfish javax json  unknown-version   FATAL  Non-parseable POM C  Users vifie  m2 repository net java jvnet-parent 3 jvnet-parent-3 pom  processing instruction can not have PITarget with reserved xml name  position  END TAG seen     lt  profiles gt  n n lt  project gt  n n lt  xml      160 7     C  Users vifie  m2 repository net java jvnet-parent 3 jvnet-parent-3 pom  line 160  column 7  It s esay in this case to understand you have just to delete directory C  Users vifie m2 repository net java jvnet-parent 3 Relaunch compilation  packaging and so on    mvn package  WARNING disappear just because you delete POM file corrupted at the good location and maven re download it  Normally the new POM file is better  Often debug mode give you messages with more comprehensive details  Why I redirect log to a file   Simply because on Windows console don t have enough buffer to store all lines and often you cannot see all lines

Sometimes this issue comes because the java.version which you have mentioned in POM.xml is not the one installed in your machine.

<properties>
    <java.version>1.7</java.version>
</properties>

Ensure you exactly mention the same version in your pom.xml as the jdk and jre version present in your machine.

I had the same problem  check the installed jre used by Maven in your Run Configuration     In your case  I think that the maven-compiler-plugin jar 2 3 2 needs a jdk1 6  To do this   Run Configuration   YOUR MAVEN BUILD   JRE   Alternate JRE  Hope this helps

I renamed the  m2 directory  this didn t help yet  so I installed the newest sdk jdk and restarted eclipse  This worked   It seems an SDK was needed and I only had installed a JRE   Which is weird  because eclipse worked on the same machine for a different older project   I imported a second maven project  and Run maven install did only complete after restarting eclipse  So maybe just a restart of eclipse was necessary   Importing yet another project  and had to do maven install twice before it worked even though I had restarted eclipse

For me  restarting Eclipse got rid of this error

Actually  if you do not want to delete your local  m2 repository     and you are have a downloaded copy of Maven from Apache  you can have Eclipse  STS use that external Maven and you can edit the  maven  conf settings xml to point your localRepository to a new empty location     lt localRepository gt C  java repository lt  localRepository gt    Of course  you will have a new repository with all of the maven source downloads in addition to your previous  m2 location

Maybe you can add this dependency to your pom xml  I use this method and solve the problem    lt dependency gt        lt groupId gt org apache maven plugins lt  groupId gt        lt artifactId gt maven-resources-plugin lt  artifactId gt        lt version gt 2 3 2 lt  version gt    lt  dependency gt

Java 9 incompatible

I got this error when trying to calling mvn install on a project.

I had installed Java 9 on macOS as well as Java 8 Update 144. My Maven project was apparently invoking Java 9 and failing. Removed Java 9 from my Mac, leaving just Java 8 in place. Maven is now happily building my project to successful completion.

Using Apache Maven 3.5.0 on macOS Sierra.

I am adding more points to the solution by @Rushi Shah

mvn clean install -X helps to identify the root cause.

Some of the important phases of Maven build lifecycle are:

clean – the project is clean of all artifacts that came from previous compilations compile – the project is compiled into /target directory of project root install – packaged archive is copied into local maven repository (could in your user's home directory under /.m2) test – unit tests are run package – compiled sources are packaged into archive (JAR by default)

The 1.6 under tag refers to JDK version. We need to ensure that proper jdk version in our dev environment or change the value to 1.7 or 1.5 or whatever if the application can be supported in that JDK version.

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.0</version>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
            </configuration>
        </plugin>
    </plugins>
</build>

We can find the complete details on Maven build lifecycle in Maven site.

Either remove the below code from the pom xml or correct your java version to make it work       lt plugin gt       lt artifactId gt maven-compiler-plugin lt  artifactId gt       lt version gt 3 0 lt  version gt       lt configuration gt         lt source gt 1 6 lt  source gt         lt target gt 1 6 lt  target gt       lt  configuration gt     lt  plugin gt
