Maven build Compilation error : Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project Maven

Java Problem Overview

I have a maven project forked and cloned from a git repo onto my eclipse. It is build on Java 8. The first thing i do is perform a

mvn clean install

But I get following failure message:

However, below is the build path details of the project which clearly has JRE - 8 set up:

and the compilation set up:

No matter how many times I build the project, i get the same error. Even after cleaning the project and refreshing it from eclipse doesn't help. Please guide.

UPDATE:

After adding the properties to set maven compiler plugin

<properties>
 <maven.compiler.source>1.8</maven.compiler.source>
 <maven.compiler.target>1.8</maven.compiler.target>
</properties>

am getting the below error:

Java Solutions

Solution 1 - Java

The error occurred because the code is not for the default compiler used there. Paste this code in effective POM before the root element ends, after declaring dependencies, to change the compiler used. Adjust version as you need.

<dependencies>
...
</dependencies>
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
    </plugins>
</build>

Solution 2 - Java

I don't think that IDE is relevant here. After all you're running a Maven and Maven doesn't have a source that will allow to compile the diamond operators. So, I think you should configure maven-compiler-plugin itself.

You can read about this here. But in general try to add the following properties:

<properties>
 <maven.compiler.source>1.8</maven.compiler.source>
 <maven.compiler.target>1.8</maven.compiler.target>
</properties>

and see whether it compiles now in Maven only.

Solution 3 - Java

If your local jdk version is 11 or 9, 10, and your project's java source/target version is 1.8, and you are using org.projectlombok:lombok package, then you can try to update its version to 1.16.22 or 1.18.12, like this:

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.16.22</version>
        </dependency>

It just solved my issue.

Solution 4 - Java

You should add the code into pom.xml like:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

Solution 5 - Java

This is an irritating error that pops up once in a while , jotting down some steps which help:

Writing answer from eclipse perspective as base logic will remain the same whether done by Intellij or command line

Rt click your project -> Maven -> Update project -> Select Force update -> Click OK
Under properties tag , add :

> 1.8 > 1.8

In some instances, you will start seeing error as we tried force update saying , failure to transfer X dependency from Y path , resolutions will not be reattempted , bla bla bla

In such case quickly fix it by cd to .m2/repository folder and run following command :

>
> for /r %i in (*.lastUpdated) do del %i

Solution 6 - Java

In my case, it was caused from an incompatibility with OpenJDK 9 (which I haven't investigated).

If you don't need JDK 9, a temporary work-around would be to purge it from your machine:

sudo apt-get remove --purge openjdk-9-jdk openjdk-9-jre 
sudo apt-get remove --purge openjdk-9-jdk-headless openjdk-9-jre-headless

Solution 7 - Java

make sure java home path is correct. for my case, java home path is wrong in pom file.

  <properties>
		<java.home>/usr/java/jdk1.8.0_45/bin/javac</java.home>
  </properties>



	
              <plugin>
 				<groupId>org.apache.maven.plugins</groupId>
                		<artifactId>maven-compiler-plugin</artifactId>
                		<version>3.5.1</version>
				<configuration>
			          <verbose>true</verbose>
			          <fork>true</fork>
			          <executable>${java.home}</executable>
				   <compilerVersion>1.8</compilerVersion>
				   <source>1.8</source>
				   <target>1.8</target>
		       	 </configuration>
	       	 </plugin>

Solution 8 - Java

Buddy,
If every this is up-to-date, even then you are having this problem, then
try running this command from the terminal directly instead of running from eclipse.
$ mvn clean install

and make sure these things:

maven is in system path
all maven dependencies are avaialble at .m2/repository
java is in system path

Solution 9 - Java

In case if you are able to compile mvn compile the project successful from terminal but not from Eclipse check out Window > Preferences >Installed JREs, make sure you have selected JRE that is under JDK (check out the paths of 2 different JRE's in pic), as Maven needs JDK to compile you need to add it.

Solution 10 - Java

I had the same problem and I Changed this

<configuration>
    <source>1.7</source>
    <target>1.7</target>
 </configuration>

here 1.7 is my JDK version.it was solved.

Solution 11 - Java

for it was comming because of java version mismatch ,so I have corrected it and i am able to build the war file.hope it will help someone

    <maven.compiler.source>1.7</maven.compiler.source>
	<maven.compiler.target>1.7</maven.compiler.target>

Solution 12 - Java

Doing this in pom.xml file and after updating the project, the problem is gone.

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.4</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
</configuration>
</plugin>

Update the pom.xml under <plugin></plugin>.
Update your project.
Then clean maven and install maven.

Solution 13 - Java

Go to the file location where the POM is stored and open cmd. Then type "mvn --v" to check the maven version and java runtime provided. Check runtime attribute and if it is "C:\Program Files\Java\jre1.8.0_191" or even close to a JRE, go to environment variables and add a new "system variable" called "JAVA_HOME" with a value "C:\Program Files\Java\jdk1.8.0_191".

Reopen the cmd and then "clean install" the project.

Solution 14 - Java

I am not able to run my own build on the other suggestions here. I even tried different versions of maven-compiler-plugin: 3.1, 3.7.0, etc.

I made it work adding this:

<testSourceDirectory>/src/test/java</testSourceDirectory>

I tried this approach because it seems like the /src/test/java directory is considered a java class that is why it is compiled the same time as /src/test/java. So my hunch were right in my case.

Maybe it is to others too, so just try this one.

Solution 15 - Java

I had the same problem, the solution was set JAVA_HOME in environment variables.

Solution 16 - Java

Worked by adding this in pom.xml:

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
</properties>

Even you have SDK 13 or 14.

Solution 17 - Java

`<maven.compiler.release>` (not `source` & `target`)

Several of the other Answers show <maven.compiler.source> & <maven.compiler.target>. Both of these are now supplanted by the simpler single element: <maven.compiler.release>.

<maven.compiler.release>15</maven.compiler.release>

So this:

  <!--old-school-->
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>15</maven.compiler.source>
    <maven.compiler.target>15</maven.compiler.target>
  </properties>

…becomes:

  <!--modern-->
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.release>15</maven.compiler.release>
  </properties>

See Question, “maven.compiler.release” as an replacement for source and target?

Solution 18 - Java

Go to: File -> Project Structure -> Project -> Switch Project SDK & Project language level to Java version 1.8

Here is example:

Solution 19 - Java

The below pom.xml configuration is making the build successful and make sure project buildpath JRE System library should point to Java8.

org.apache.maven.pluginsmaven-compiler-plugin3.7.0 1.81.8

Solution 20 - Java

Jdk 9 and 10 solution

<plugins>
		<plugin>
			<groupId>org.apache.maven.plugins</groupId>
			<artifactId>maven-compiler-plugin</artifactId>
			<version>${maven-compiler.version}</version>
			<configuration>
				<source>${java.version}</source>
				<target>${java.version}</target>
				<debug>true</debug>
			</configuration>
			<dependencies>
				<dependency>
					<groupId>org.ow2.asm</groupId>
					<artifactId>asm</artifactId>
					<version>6.2</version>
				</dependency>
			</dependencies>
		</plugin>

and make sure your maven is pointing to JDK 10 or 9. mvn -v

Apache Maven 3.5.3 (3383c37e1f9e9b3bc3df5050c29c8aff9f295297; 2018-02-24T14:49:05-05:00)
Maven home: C:\devplay\apache-maven-3.5.3\bin\..
Java version: 10.0.1, vendor: Oracle Corporation
Java home: C:\Program Files\Java\jdk-10.0.1
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

Solution 21 - Java

Add the following in your pom.xml and do CTRL+S, it will automatically build the project.

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-compiler-plugin</artifactId> 
    <version>3.5.1</version> 
    <configuration>
        <source>1.8</source> 
        <target>1.8</target> 
    </configuration> 
</plugin>

Now click on Run as >Maven Test.

This error will definitely get solved.

Solution 22 - Java

My issues was that I was running mvn compile from a child project directory instead of the parent project.

Solution 23 - Java

For me it seemed to be all the answers on this page, plus the right JDK. I added the properties:

	<maven.compiler.source>1.8</maven.compiler.source>
	<maven.compiler.target>1.8</maven.compiler.target>

and the JDK 1.8 plug-in pointing to my open JDK from Redhat:

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
            <fork>true</fork>
            <executable>C:\java\java-1.8.0-openjdk\bin\javac.exe</executable>
            <source>1.8</source>
            <target>1.8</target>
        </configuration>
    </plugin>

and ran

mvn clean verify

and got build success. Yay.

Edit: I think this is actually what made the difference: https://mkyong.com/eclipse/eclipse-ide-no-compiler-is-provided-in-this-environment-perhaps-you-are-running-on-a-jre-rather-than-a-jdk/

Solution 24 - Java

In my case, I set the JAVA_HOME correctly but still had problem for hours! Finally I found out that I had settings.xml in .m2 directory and the java home was set there and pointed to another path. I ran the following command to find out what java path the maven is using:

mvn clean install -X | grep -i "executable"

Then I corrected the java home path in the settings.xml in .m2 directory and problem solved!

Solution 25 - Java

Note: if you have your project under File->Project Structure setup for one specific version of Java and you have your Pom.xml setup for a different version of Java, you will get this error. For example, running Java 8 under Project Structure and Java 11 in your pom.xml.
