If I call mvn install for example, the test phase being located before in the hierarchy should be executed. However it seems not to be the case.
I actually need to specify it manually: mvn test install in order for my tests to be executed.
OR
Respecifying the surefire plugin in the pom.xml:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.4.2</version>
</plugin>
The test phase is supposed to call the maven-surefire-plugin which is a core plugin.
This behavior doesn't seem consistent to me. Am I missing something ?
EDIT: I am using Maven 3.2.1
The Maven version I am using (3.2.1) embeds the version 2.12.4 of the maven-surefire-plugin.
My project was a study case and had no test classes in it.
The 2.4.2 version of maven-surefire-plugin must fetch by default the Test reports even if no test class is encountered. The 2.12.4 seems not to behave this way.
When I was specifying the maven-surefire-plugin, I was overriding the plugin definition to the version to 2.4.2.
My apologies for having taken your attention for such an edge case and also with a lack of details.

I'm getting ArrayStoreException: TypeNotPresentExceptionProxy when running integration-test with maven-failsafe-plugin and spring-boot 1.4.
You can see this error if you run joinfaces-example with
mvn -Pattach-integration-test clean install
I realized that the error does not occur if I change spring-boot-maven-plugin to run at pre-integration-test phase instead of package one.
More, this error started when I upgraded spring boot to 1.4. No error occurs if I change jsf-spring-boot-parent version to 2.0.0 which uses spring boot 1.3 version.
I actually found the answer in Spring Boot 1.4 release notes, short answer is that maven-failsafe-plugin is not compatible with Spring Boot 1.4's new executable layout. Full explanation below :
As of Failsafe 2.19, target/classes is no longer on the classpath and
the project’s built jar is used instead. The plugin won’t be able to
find your classes due to the change in the executable jar layout.
There are two ways to work around this issue:
Downgrade to 2.18.1 so that you use target/classes instead
Configure the spring-boot-maven-plugin to use a classifier for the
repackage goal. That way, the original jar will be available and used
by the plugin. For example :
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<classifier>exec</classifier>
</configuration>
</plugin>
An alternative is documented here: https://github.com/spring-projects/spring-boot/issues/6254
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<!--
Make failsafe and spring-boot repackage play nice together,
see https://github.com/spring-projects/spring-boot/issues/6254
-->
<configuration>
<classesDirectory>${project.build.outputDirectory}</classesDirectory>
</configuration>
</plugin>
This worked better for me, because when I used the "exec" solution, Spring failed to find my configuration files when starting the container. Which could probably be fixed by adding some further configuration parameters, I suppose, but this solution works "out of the box" for me.
In my maven project I have a number of modules. Is it possible to turn off running unit test for some modules via command line options?
My project takes about 15 mins to run through all unit tests. I would like to speed up the overall build by running just the unit tests in the module I am working on. I do not want to go in and edit each individual pom.xml to achieve this.
I have tried a solution outlined here: Can I run a specific testng test group via maven? However the result is a lot of test failures in modules that I want to skip. I suppose 'group' is not the same concept of module?
To toggle unit tests on and off for an entire project use Maven Surefire Plugin's capability of skipping tests. There is a drawback with using skipTests from the command line. In a multi-module build scenario, this would disable all tests across all modules.
If you need more fine grain control of running a subset of tests for a module, look into using the Maven Surefire Plugin's test inclusion and exclusion capabilities.
To allow for command-line overrides, make use of POM properties when configuring the Surefire Plugin. Take for example the following POM segment:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.9</version>
<configuration>
<excludes>
<exclude>${someModule.test.excludes}</exclude>
</excludes>
<includes>
<include>${someModule.test.includes}</include>
</includes>
</configuration>
</plugin>
</plugins>
</build>
<properties>
<someModule.skip.tests>false</someModule.skip.tests>
<skipTests>${someModule.skip.tests}</skipTests>
<someModule.test.includes>**/*Test.java</someModule.test.includes>
<someModule.test.excludes>**/*Test.java.bogus</someModule.test.excludes>
</properties>
With a POM like the above you can execute tests in a variety of ways.
Run all tests (the above configuration includes all **/*Test.java test source files)
mvn test
Skip all tests across all modules
mvn -DskipTests=true test
Skip all tests for a particular module
mvn -DsomeModule.skip.tests=true test
Only run certain tests for a particular module (this example includes all **/*IncludeTest.java test source files)
mvn -DsomeModule.test.includes="**/*IncludeTest.java" test
Exclude certain tests for a particular module (this example excludes all **/*ExcludeTest.java source files)
mvn -DsomeModule.test.excludes="**/*ExcludeTest.java" test
Found a way to exclude on command line:
# Exclude one test class, by using the explanation mark (!)
mvn test -Dtest=!LegacyTest
# Exclude one test method
mvn verify -Dtest=!LegacyTest#testFoo
# Exclude two test methods
mvn verify -Dtest=!LegacyTest#testFoo+testBar
# Exclude a package with a wildcard (*)
mvn test -Dtest=!com.mycompany.app.Legacy*
This is from: https://blog.jdriven.com/2017/10/run-one-or-exclude-one-test-with-maven/
…and if you like to pass the parameter to maven release plugin in Hudson/Jenkins you have to use
-Darguments=-DskipTests
to get it work.
If you want to use Maven profiles:
http://maven.apache.org/guides/introduction/introduction-to-profiles.html
you might want to make it work doing something like this:
Skipping tests in some modules in Maven
I don't know if there is a supported command line option that does the same.
You also might try using environment properties directly, something as per this doc page:
http://maven.apache.org/plugins/maven-surefire-plugin/examples/skipping-test.html
i.e. something like:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.12</version>
<configuration>
<skipTests>${moduleA.skipTests}</skipTests>
</configuration>
</plugin>
then using mvn -DmoduleA.skipTests=false test to test that one module.
I have an interesting problem in a project where all of the technologies mentioned in the title are used. I've been able to track it down up to the diagnosis (the test classpath prepared by Surefire), but I don't understand whether it can be fixed and how. It's not a showstopper, indeed it's a minor issue for me, but I'd like to solve it anyway.
First a rough description.
The problem is related to executing tests in a specific module of the project, and only in a specific way.
Everything works (tests pass) when I run from the master pom level:
cd ${projHome}
mvn install
Everything works (tests pass) when I run:
cd ${projHome}/modules/CoreImplementation/
mvn test
That means that I can build and test with no problems, the same for my Jenkins, and NetBeans can run tests from the IDE when I need them.
But that module fails testing when I run from the master pom level:
cd ${projHome}
mvn test
with this error:
java.lang.NoSuchMethodError: it.tidalwave.northernwind.profiling.RequestProfilerAspect.aspectOf()Lit/tidalwave/northernwind/profiling/RequestProfilerAspect;
at it.tidalwave.northernwind.frontend.ui.spi.DefaultSiteViewController.processRequest(DefaultSiteViewController.java:82) ~[classes/:na]
at it.tidalwave.northernwind.frontend.ui.spi.DefaultSiteViewControllerTest.must_call_some_RequestProcessors_when_one_breaks(DefaultSiteViewControllerTest.java:161) ~[test-classes/:na]
Running mvn test as a second pass (after a mvn install -DskipTests) happens to be the way Drone.io and Travis do their job. While I could change their configuration, I'd like to stay with the standard configuration and fix the problem if possible.
The diagnosis in short and my question.
Now, the question in short (details are further below). I was able to track down the problem to different ways in which Surefire prepares the classpath to execute the tests.
When I run mvn install the classpath is:
${repo}/org/apache/maven/surefire/surefire-booter/2.16/surefire-booter-2.16.jar
${repo}/org/apache/maven/surefire/surefire-api/2.16/surefire-api-2.16.jar
${projHome}/modules/CoreImplementation/target/test-classes
${projHome}/modules/CoreImplementation/target/classes
${projHome}/modules/Core/target/it-tidalwave-northernwind-core-1.1-ALPHA-37-SNAPSHOT.952b0c8bdc77.jar
${repo}/it/tidalwave/thesefoolishthings/it-tidalwave-role/3.0-ALPHA-1/it-tidalwave-role-3.0-ALPHA-1.jar
${projHome}/modules/Profiling/target/it-tidalwave-northernwind-core-profiling-1.1-ALPHA-37-SNAPSHOT.952b0c8bdc77.jar
${repo}/org/apache/commons/commons-math3/3.0/commons-math3-3.0.jar
…
When I run mvn test (from the project home) the classpath is:
${repo}/org/apache/maven/surefire/surefire-booter/2.16/surefire-booter-2.16.jar
${repo}/org/apache/maven/surefire/surefire-api/2.16/surefire-api-2.16.jar
${projHome}/modules/CoreImplementation/target/test-classes
${projHome}/modules/CoreImplementation/target/classes
${projHome}/modules/Core/target/unwoven-classes
${repo}/it/tidalwave/thesefoolishthings/it-tidalwave-role/3.0-ALPHA-1/it-tidalwave-role-3.0-ALPHA-1.jar
${projHome}/modules/Profiling/target/unwoven-classes
${repo}/org/apache/commons/commons-math3/3.0/commons-math3-3.0.jar
…
The different portions are the indented ones. In the former case, SureFire uses the classes directory (forget for a moment that in my case they are named unwoven-classes) only for the module under test, and the installed jar files for every dependency. In the latter case, it seems to be using classes for all dependencies in the reactor.
The reason for which this difference in the classpaths gives me troubles is explained below in the "Gory details" section. In short, that unwoven means that they contain bytecode not augmented by AspectJ, hence the methods that can't be found at runtime.
I'm running with SureFire 2.16, but I've also tried the latest 2.19 with no changes. Being able to force SureFire to always use jar files for dependencies would fix my problems. If you have the answer, you can stop reading my post here.
Gory details (just for curiosity).
The faulty module artifactId is it-tidalwave-northernwind-core-default and it depends on aspects available in it-tidalwave-northernwind-core-profiling - that's where the offending RequestProfilerAspect is. The aspect library dependency is both in the regular dependencies of the faulty module and in the configuration of the aspectj plugin:
<dependency>
<groupId>it.tidalwave.northernwind</groupId>
<artifactId>it-tidalwave-northernwind-core-profiling</artifactId>
</dependency>
...
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>
<configuration>
<aspectLibraries combine.children="append">
<dependency>
<groupId>it.tidalwave.northernwind</groupId>
<artifactId>it-tidalwave-northernwind-core-profiling</artifactId>
</dependency>
</aspectLibraries>
</configuration>
</plugin>
</plugins>
</build>
AspectJ integration is by means of the following profile in a Super POM, which is activated in the build, whose relevant part is:
<profile>
<id>it.tidalwave-aspectj-springaop-v1</id>
...
<build>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<executions>
<execution>
<id>default-compile</id>
<phase>compile</phase>
<configuration>
<outputDirectory>target/unwoven-classes</outputDirectory>
</configuration>
</execution>
<execution>
<id>default-testCompile</id>
<phase>test-compile</phase>
<configuration>
<outputDirectory>target/unwoven-test-classes</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
...
The aspectj plugin is configured in the profile to statically weave binaries in the unwoven-test-classes directories. The reason for this approach is that it's the only feasible solution AFAIK to have both Lombok and AspectJ work together.
Now, back to the two classpaths described above: the fact that SureFire is using unwoven-classes means that it's pointing to bytecode that has not been augmented with AspectJ methods, hence the error.

I dont know if this is a question or suggestion. But I am going to ask it as a question cos may be i am doing something wrong.
My problem was that I wanted to skip tests in maven build, In eclipse plugin I checked the Skip Test option in configuration when running maven. It was still failing on the Test surefire plugin as it couldn't download the version 2.4.3 (even though my previous maven project used a 2.7.2 and it was already there in my repo) So i tried with skipping tests and it still failed.
I configured my POM to use the 2.7.3 plugin of surefire which i already had and it went forward only to say Skipping Tests. Now, my confusion is that when it was already going to SKIP the test part why bother going into the download and confirming if the plugin for surefire is there or not. Just Skip it I say..
well, Is that the normal behavior of maven that when you skip something the plugin is still downloaded as if you are going to use it. Or was I doing it wrongly that made it download it.
May be because there was something new called "Effective POM" and it contained a listing of surefire plugin 2.4.2 in the plugin management area, when i imported my maven project in eclipse using the m2eclipse and i couldnt edit the Effective POM. I had not seen this before in the NetBeans when making the maven project.
In order to work i added an unnecessary surefire plugin entry in my build profile and skipped the tests there as well and added the version that I had in my repo already. I only did this so that my project can be built under eclipse as well. other wise my project works in NetBeans and simple command line without any issues.
Any comments!!
I think maven should be able to see first the SKIP part and then proceed into the usage of the plugin.
Syed..
Based on what you mentioned you didn't understand the difference between using a plugin and configuring the plugin. In this case you are using the plugin (it's in your build area or as you already figured out coming via super-pom). Furthermore you are trying to skip the tests despite the fact that maven-surefire-plugin in version 2.7.3 does not exist.
The configuration parameter skip will not execute the tests as well as not compile them. If you wan't just ignore the tests for a limited time you can use the "skipTest" parameter which in contradiction to skip will continue to compile the tests.
I would recommend to use a pluginManagement section of your project or your parent pom to define the version of the maven-surefire-plugin (which in the meantime exists in version 2.12)...
The following snippet add the pluginManagement part to a pom which controls which version of the maven-surefire plugin will be used.
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.11</version>
</plugin>
</plugins>
</pluginManagement>
<plugins>
..
</build>
After you inserted that into your project pom the output effective pom should give you the version...otherwise you might need to update the project configuration first.
Compiling and running tests is part of the default lifecycle of maven. Since maven uses surefire to do run tests, it needs to download surefire. skipTests is not a maven configuration, but a surefire plugin configuration. The plugin determines that maven needs to skip tests.
As for 2.4.3 of surefire plugin, it is a valid version, but will work with 2.0.6 version of maven. Most likely you are using a newer maven, but, for some reason have the super pom of the older maven version on your system.
skipTest doesn't tell maven to skip the test lifecycle, it tells the surefire plugin not to run them. The plugin is still part of the lifecycle (it just does nothing when it's called). Hence your error.
If you want to NOT have surefire at all, you need to define your own packaging (since surefire is part of the standard jar packaging lifecycle) - which is a lot more work than just choosing a version of surefire that works for you (add a section with the right in your section).
I'm trying to convert a project from ant to maven.
The unit tests depend on a third party binary jar, which is not available in any public maven repositories.
How do I make maven handle this situation? I have found two solutions, neither of which are acceptable. First is to use a system dependency; this doesn't work because a) the dependency should only be for the tests, and b) the dependency is not found by eclipse after generating an eclipse project.
Second is to manually install the dependency in a local repository. This seems to be the recommended way. I don't want to do this because I want users to be able to build and test with a simple 'mvn test'. If users have to read a document and copy/paste some shell commands to be able to build and test, then something's wrong.
I suppose it would be OK if maven itself installed the dependency in the local repository as part of the build - is this possible, and if so, how?
Aled.
You may want to look at install:install-file. You can make it execute in the early phase of your project (validate or initialize) via standard means.
On the second thought, if it fails because of missing dependency in the same project, there are couple more options. One is to call ant script via antrun plugin to install artifact.
Or create additional module not dependent on your artifact to be executed prior to main module and have that module install artifact as described earlier.
First of all my way would be using a repository manager such as nexus and installing this dependency to there.
However there is another solution. You can include this 3rd party jar to your project and with test plugin you can configure to include it in classpath such this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.10</version>
<configuration>
<additionalClasspathElements>
<additionalClasspathElement>path/to/additional/resources</additionalClasspathElement>
<additionalClasspathElement>path/to/additional/jar</additionalClasspathElement>
</additionalClasspathElements>
</configuration>
</plugin>
By the way, I hope that you are aware of that maven is executing surefire plugin in order to run tests by default lifecycle.
