Trying to use maven toolchains to compile a Java 17 project while my active jdk is JDK8. I set up my toolchains so they use JDK17 to compile it, and this compilation fails while running tests with error:
Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin:3.0.0-M7:test failed: java.lang.UnsupportedClassVersionError: my/source/ControllerTest has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0.

why isn't my toolchain config getting picked up by surefire. Compilation itself is fine, but surefire test phase fails. Appreciate your help
I was able to get toolchains working if i trigger tests with "mvn test" on surefire plugin 2.22. It doesn't pick up the toolchains though if the tests are triggered with surefire:test.
I have been trying to make it work on surefire 3 but i keep running into the same issue that you posted about. Please let me know as well if you found a way to make this work with surefire 3.

I had a working Eclipse project for which I could export a .jar file with no problems.
I then did a 'configure/convert to maven'. Now, when I try to export the .jar file I get the error message:
Fat Jar Export: Could not find class-path entry for 'Users/ward/dropbox/workspaces/newautomation/workspace/automation/target/test-classes'.
Although it does write the .jar file, the .jar file does not work properly.
Any help?

As stated in my question, I had a project running in Eclipse and could successfully 'export a runnable jar' using Eclipse. That allowed me to distribute my project as a self contained '.jar' and run it on other systems with a simple:
java -jar project.jar
I am using Eclipse 4.3.0.
I decided I wanted to covert the project to a 'maven project' and did so using eclipse 'project/configure/convert to maven'.
I then found that my old mechanism for creating a .jar no longer worked.
Casting about the internet I finally found the information I needed. The first bit of information was that I needed to create what was called a 'Fat Jar'. When using maven, one creates a 'Fat Jar' by running maven, NOT using the export function in Eclipse. To create a 'Fat Jar', one needs to click on 'Project/Run As' and select 'maven build'. That will get you to a screen where you specify 'Goals'. Ultimately, for me, the goals were "compile assembly:single".
Doing this for the first time will result in warnings and errors. The most important error is:
Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.2-beta-5:single
This is because the 'pom.xml' file created by the 'convert' process is incomplete. After several frustrating hours, here is what I finally made work. Again, to create the 'Fat Jar', I do:
project/Run As/Maven build
with goals: compile assembly:single
My 'pom.xml' is:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

Final notes:
The section concerning 'UTF-8' is not strictly needed, it just gets rid of an annoying warning.
There may be other 'unneeded' lines in the 'pom.xml'.
The 'compile' may be unnecessary but I found that when editing the pom.xml file I often got rid of Eclipse syntax type errors by running 'compile' and so I just do it as a matter of course now.
I have added below properties in pom.xml for surefire plugin but its still filing with below error
<argLine>-XX:MaxPermSize=512m</argLine>
<argLine>-XX:+UnlockCommercialFeatures</argLine>
<argLine>-XX:+FlightRecorder</argLine>
Error: To use Flight Record first Unlock UnlockCommercialFeatures.
Any suggesting with sample pom.xml configurtion
My observation is when I run Maven build this feature is enabled for main thread but not enabled for the fork thread created by surefire pluin
You cannot use argLine repeatedly. You need to use something along the lines of
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<argLine>#{argLine} -XX:+UnlockCommercialFeatures -XX:+FlightRecorder -XX:StartFlightRecording=duration=1000s,filename=surefire.jfr</argLine>
</configuration>
</plugin>
instead. A similar setup works for failsafe.
I was going through the io.qameta.allure documentation and saw this option to generate allure report using "mvn allure:serve"
mvn allure:serve
The report will be generated into a temp folder. The web server with results will start. You can additionally configure the server timeout
regarding the below lines, can we modify in the configuration to generate reports under the particulate folder instead of the temp folder?
do anyone have information about it using this command only?
You can do it by defining a configuration > reportDirectory for allure-maven in your pom.xml file.
Example: in a java/selenium/testng project, here is the reporting section of pom.xml file:
<reporting>
<excludeDefaults>true</excludeDefaults>
<plugins>
<plugin>
<groupId>io.qameta.allure</groupId>
<artifactId>allure-maven</artifactId>
<version>2.10.0</version>
<configuration>
<reportVersion>${allure.version}</reportVersion>
<reportDirectory>allure-report/</reportDirectory>
</configuration>
</plugin>
</plugins>
</reporting>
In order to generate allure reports you need to use: mvn allure:report.
To specify the path of the report generated use the allure maven plugin and in the pom.xml file use this:
<configuration>
<reportVersion>2.14.0</reportVersion>
<resultsDirectory>*allure result path*</resultsDirectory>
<reportDirectory>*allure report path*</reportDirectory>
</configuration>
The following command: mvn allure:serve always uses a temp folder on your device and I haven't seen anywhere in their documentation the ability of defining the path when using the serve command.
I have created a Java test (i can convert it to Junit as well if required). I want it to invoke when the project build. I added the dependency in the Pom.xml but on building the project, the test is not triggered. I think the Surefire plugin is not invoked in the first place because i can not see any reports in the target folder.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19.1</version>
<configuration>
<includes>
<include>com.configtests/ConfigTests.java</include>
</includes>
</configuration>
</plugin>
Generally, you have this kind of structure:
Module
-- src
-- main
-- java
-- com.module
-- (classes)
-- test
-- java
-- com.module
-- (test classes)
-- pom.xml
Then the plugin syntax looks like this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19.1</version>
<configuration>
<includes>
<include>*</include>
</includes>
</configuration>
</plugin>
I assume you want to have ConfigTests.java under the package you have named com.configtests in the test directory. Should suffice to just do:
<include>ConfigTests.java</include>
No reason to declare the package prepended. It should find the class properly so long as you have the pom.xml at the top-level and the class under a folder in the same directory accordingly (in the test folder!)
EDIT:
Also, to run the tests as part of your build it should be running the tests auto-magically with: mvn clean install or, you can run the tests isolated like mvn test. Output in the console will indicate if the tests were run or not.
I'm using xmlbeans to generate some java classes. I'm using maven 3 in my project.
I have included the dependency and the plugin details as shown below.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>xmlbeans-maven-plugin</artifactId>
<version>2.3.3</version>
<executions>
<execution>
<goals>
<goal>xmlbeans</goal>
</goals>
</execution>
</executions>
<inherited>true</inherited>
<configuration>
<schemaDirectory>src/main/xsd</schemaDirectory>
</configuration>
</plugin>
When I run a clean package goal I get compiler errors simply because the classes which uses the xmlbeans generated reference are not found in the classpath. This is because the xmlbeans classes are not compiled into the right directory structure. rather it just places it in the target\classes\aseXMLR30 (where as it should be in the formal structure ex: com.ex.first)
I have googled and read many blogs nothing helped me so far!
any replies/answers are really appreciated!
I know this question is 4 months old but in case you and/or others are still looking for a solution, this blog post may be able to provide a clue.
Essentially, what it says is that all references to org.maven.ide.eclipse should be replaced by org.eclipse.m2e. It references .launch files but to be on the safer side just grep recursively through your Eclipse directory and projects.
