How to ignore the specific failed unit test result in Maven build?

I have some unit tests under Integration.java. I want Maven to ignore the test results of this class as they fail rarely (due to external server maintenance). But I don't want to ignore them from running as I need them for code coverage.
I've tried this configuration
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<includes>
<include>IntegrationTest.java</include>
</includes>
<testFailureIgnore>true</testFailureIgnore>
</configuration>
</plugin>
This seems to be working by ignoring the failed tests. But the problem with the above configuration is, it is ignoring the failed tests at other classes as well.
I want all the tests under Integration.java needs to be executed but It shouldn't have any impact on the build to determine success/failure.
But, the build should fail if any test cases fail under any other Test classes other than Integration.java

Like #khmarbaise has mentioned, It needs to be handled by maven-failsafe not surefire plugin
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<configuration>
<includes>
<include>*IntegrationTest.java</include>
</includes>
</configuration>
<executions>
<execution>
<id>failsafe-integration-tests</id>
<phase>integration-test</phase>
<goals>
<goal>integration-test</goal>
</goals>
</execution>
</executions>
</plugin>
By using maven-failsafe-plugin I made sure the test cases run and for the good code coverage and the build will not fail even if the upstream is down.

Surefire by default includes all test classes whose name starts with Test/ends with Test/Tests/TestCase.
You can use excludes and includes parameters as per your need :
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.21.0</version>
<configuration>
<excludes>
<exclude>DataTest.java</exclude>
</excludes>
<includes>
<include>DataCheck.java</include>
</includes>
</configuration>
</plugin>

Is possible to run same test multiple times with Maven Surefire Plugin?

There is a config value rerunFailingTestsCount but I want to run a test method a configurable number of times even it is successful. Are there any options?

I don't think it is possible to configure maven-surefire-plugin to rerun passing tests.
However, you can configure the invocation count of a single test using the TestNG (not JUnit) #Test annotation:
#Test(invocationCount = 5)
public void testSomething() {
}
This will result in the testSomething method being tested 5 times.
If you don't want to go the TestNG route, you can refer to this answer for a solution with JUnit.

If you want to have it configurable by implementing the IInvokedMethodListener beforeInvocation method, something to the effect :
method.getTestMethod().setInvocationCount(Integer.parseInt(System.getProperty("configurablecount")));
System.getProperty can be replaced by however you want to configure it. You can also probably control which tests to set the invocation count to change by passing testnames.

maven surefire plugin executes excludes also

I have the following configuration for using maven-surefire-plugin to execute my integration tests and unit tests..
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.16</version>
<executions>
<execution>
<id>unit-tests</id>
<phase>test</phase>
<goals>
<goal>test</goal>
</goals>
<configuration>
<excludes>
<exclude>**/*Test.java</exclude>
<exclude>**/*TestCase.java</exclude>
</excludes>
<includes>
<include>**/MySuite.java</include>
</includes>
</configuration>
</execution>
<execution>
<id>integration-tests</id>
<phase>integration-test</phase>
<goals>
<goal>test</goal>
</goals>
<configuration>
<skip>true</skip>
<includes>
<include>**/BarSuite.java</include>
</includes>
</configuration>
</execution>
</executions>
</plugin>
However, when executing the unit tests it appears to run my individual test classes as well as executing the suite which runs those same classes. How can I configure it to only execute that of which i include? i.e the suite? (MySuite)
thanks,

I've noticed that there appears to be an execution with id default-test that occurs even if I don't configure it.
By explicitly configuring an execution with this id, I can control it. In your case telling it to exclude ** might solve your problem.

Without a build log I can't tell for sure, but from your description here is what I suspect. The surefire plugin is bound to the lifecycle by default, for jars, wars, ears. What you have done with your configuration is to add two additional plugin executions, however you did not change the default execution. You should be able to see this by adding -X to the mvn command and counting the number of surefire plugin executions.
To override the default, change the id of the first execution to "default-test" and see if that does the trick.

How to process annotations with Maven?

I'm trying to process annotations with my own annotations processor in a maven project. Using org.bsc.maven:maven-processor-plugin I had some success, but many problems.
I wonder if there is a demo project comparable to my usage scenario I could compare to.

Surprisingly all what was needed is adding a dependency on the project with the annotation processor.
dp4jmaventest is a sample project for dp4j annotations processor.
My problem was that of trying to process annotations in classes within the same annotation processing project. The solution is to compile on two phases.
</configuration>
<executions>
<execution>
<id>default-compile</id>
<configuration>
<compilerArgument>-proc:none</compilerArgument>
<includes>
<include>com/dp4j/**</include>
<include>com/dp4j/processors/core/**</include>
<include>com/dp4j/processors/**</include>
</includes>
</configuration>
</execution>
<execution>
<id>compile-everything-else</id>
<phase>compile</phase>
<goals>
<goal>compile</goal>
</goals>
</execution>
</executions>

dp4j maven project is a working example project.

Generating sources by running a project's java class in Maven

I'm converting a largish Ant build to Maven. As part of the Ant build, we have several steps which created Java classes by invoking one of the project's classes, simplified as:
javac SomeGenerator.java
java SomeGenerator generated # generate classes in generated/
javac generated/*.java
I've split each generator in its own Maven module, but I have the problem of not being able to run the generator since it's not yet compiled in the generate-sources phase.
I've tried something similar to
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.1.1</version>
<executions>
<execution>
<id>generate-model</id>
<goals>
<goal>java</goal>
</goals>
<phase>generate-sources</phase>
<configuration>
<mainClass>DTOGenerator</mainClass>
<arguments>
<argument>${model.generated.dir}</argument>
</arguments>
</configuration>
</execution>
</executions>
</plugin>
Which sadly does not work, for the reasons outlined above. Splitting the code generators into two projects each, one for compiling the generator and another for generating the DTOs seems overkill.
What alternatives are there?
Using Maven 2.2.1.

You can execute the maven-compile-plugin in the generate-sources phase. Just add another execution before the existing execution and configure it so that it just picks up the sources for the generator.
Or split the project in two: build the generator with a separate POM and include the generator library as a dependency to the POM that's generating the sources.
Personally I would split the project. Keeps the build files cleaner and easier to maintain.

I didn't want to have 2 different projects, so I tried to setup Maven for adding the generated compiled code to the final jar package.
This is the working solution I've used:
In process-classes phase (executed just after the compile phase):
exec-maven-plugin for executing a main class able to generate my source files in target/generated-sources/java folder (in my specific case I used the Roaster library for source code generation);
build-helper-maven-plugin for adding the generated sources in the correct location
In prepare-package phase:
maven-compiler-plugin, in order to detect the changes and recompile the module
maven-jar-plugin for producing the jar package
This is my pom.xml:
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.6.0</version>
<executions>
<execution>
<phase>process-classes</phase>
<goals>
<goal>java</goal>
</goals>
<configuration>
<mainClass>com.example.MyClassWriter</mainClass>
<arguments>
<argument>${project.basedir}</argument>
<argument>${project.build.directory}</argument>
</arguments>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>3.0.0</version>
<executions>
<execution>
<phase>process-classes</phase>
<goals>
<goal>add-source</goal>
</goals>
<configuration>
<sources>
<source>${project.build.directory}/generated-sources/java</source>
</sources>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.6.1</version>
<executions>
<execution>
<phase>prepare-package</phase>
<goals>
<goal>compile</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>

<version>3.0.2</version>
<executions>
<execution>
<phase>prepare-package</phase>
</execution>
</executions>
</plugin>
</plugins>
</build>

In order to do this in one project, there are 3 steps:
Compile generator code
We can do it in generate-sources phase, using maven-compiler-plugin. You can also exclude other source files.
Run generator to generate code
We can do it in process-sources phase, using exec-maven-plugin.
Compile project
Below is the key part of pom.xml
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.0</version>
<configuration>
<source>1.8</source>
<target>1.8</target>

<include>source/file/of/generator/*.java</include>
</includes>
<excludes>
<exclude>other/source/files/*.java</exclude>
</excludes>
</configuration>
</execution>
</executions>
</plugin>
<plugin>

<phase>process-sources</phase>
<configuration>
<mainClass>your.main.class.of.generator</mainClass>
</configuration>
</execution>
</executions>
</plugin>

We faced the same problem. We wanted to respect Maven's behavior as closely as possible, to have no problems with plugins and so on... Fighting Maven is just too expensive!
We realized that the update frequency of the generated code was usually very different from the one of the code that we manually write, so separating the code had very good performance characteristics for the build. So we accepted to have our generated classes as a dependency of the manually written.
We adopted the following structure, that had just one little change from a regular maven config, a change in the source directory.
Parent project : Generations
We created a parent project for all our generations.
It has a JAR type if it contains code to be compiled, otherwise POM.
There we have our generating code, in /src.
It can compile in /target as usual.
It runs the generation, each generator producing code in a sub-directory of /target.
Note: if you want several generated results in the same jar, just put them in the same sub-directory.
Child jar projects : Generateds
It is a subdirectory of the Generations project.
It has a JAR type.
The source directory points to the sub-directory in the parent's target.
<sourceDirectory>../target/generated1</sourceDirectory>
It compiles normally in its own /target directory.
That structure allows us to :
have as little modification to the standard maven layout as possible, so every maven command and plugin keeps working nicely.
scale nicely if you have several generators,
scale nicely if you want to generate several jars (we had a case wsdl2java where one generator produced code that should be split into several jars ; each child generated project would have the same source directory, but would be configured with an <includes> to handle only some of the classes).

I posted a minimal working setup here https://github.com/baloise/inlinesourcecodegenerator
It uses build-helper compiler and exec plugins and has all code in the same project.
