I am using a maven dependency which require me to pass add-module during compilation and runtime as mentioned here.
Can someone let me know how can I pass --add-module option to a spring boot application during compilation and runtime? It will be good if I can control both compilation and runtime behaviour from the pom.xml.
For compilation you can use the maven-copmiler-plugin in your build of your pom.xml.
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>compile</goal>
</goals>
<configuration>
<parameters>true</parameters>
</configuration>
</execution>
</executions>
<configuration>
<source>14</source>
<target>14</target>
<compilerReuseStrategy>reuseSame</compilerReuseStrategy>
<compilerArgs>
<arg>--enable-preview</arg>
<arg>--add-modules=jdk.incubator.foreign</arg>
</compilerArgs>
</configuration>
</plugin>
</plugins>
</build>
As you see I have included also the --enable-preview. In JDK14 as reported in JEPS 370 it is not needed since this is not a preview feature. But keep an eye on it since it might be needed in other jdk versions since in some versions this belongs in preview features.
As for runntime a spring-boot application is normally just a .jar executable file which you start with the normal java -jar myApp.jar command.
According to oracle documentation, the format of the command line is
To execute a JAR file:
java [options] -jar jarfile [args...]
So the command you want would be
java --add-modules jdk.incubator.foreign -jar myApp.jar
I'm trying to add Bytecode Enhancement to my Maven Spring project created with Spring Initializr, so that I can use lazyloading in a #Formula, whoever, it's not working
I've added the plugin to the build > plugins section of my pom.xml:
<plugin>
<groupId>org.hibernate.orm.tooling</groupId>
<artifactId>hibernate-enhance-maven-plugin</artifactId>
<version>${hibernate.version}</version>
<executions>
<execution>
<configuration>
<failOnError>true</failOnError>
<enableLazyInitialization>true</enableLazyInitialization>
<enableDirtyTracking>false</enableDirtyTracking>
<enableAssociationManagement>false</enableAssociationManagement>
<enableExtendedEnhancement>false</enableExtendedEnhancement>
</configuration>
<goals>
<goal>enhance</goal>
</goals>
</execution>
</executions>
</plugin>
If I run the goal manually, I get the following warning:
[WARNING] Skipping Hibernate bytecode enhancement plugin execution since no feature is enabled
I saw only one other mention of this problem on the internet, and they said that it was probably a configuration problem with Maven, because the plugin is not able to read those properties on the .xml, but what could I do? This is basically a fresh Spring Initializr project.
This question already has answers here:
Maven deploy multiple wars to embedded server for integration tests
(2 answers)
Closed 3 years ago.
I have two applications (Maven 'war' artifact), let's call them Api and Ui.
I want to setup a fully automated integration test that fires up Api and Ui locally before executing integration tests.
The applications are losely-coupled and so I don't want to introduce any dependency on Api in Uis build or vice-versa.
So I want to setup a third project, IntegratedQA which will have dependencies on both apps.
My initial POM contains:
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat8-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
<path>/</path>
</configuration>
<executions>
<execution>
<id>start-tomcat</id>
<phase>pre-integration-test</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<fork>true</fork>
</configuration>
</execution>
<execution>
<id>stop-tomcat</id>
<phase>post-integration-test</phase>
<goals>
<goal>shutdown</goal>
</goals>
</execution>
</executions>
</plugin>
My question is... How exactly do I tell tomcat to launch Api.war and Ui.war, which are built in separate projects?
Using tomcat7-maven-plugin you can customize the tomcat7:deploy to provide the war files path to deploy into tomcat environment.
browse this link for the documentation.
Linking another stackoverflow answer where it is specified how it will work with tomcat 8 or 9
Jenkins deploy war file to Tomcat 8
I have a Spring boot app deployed into PCF cloud. I need to setup a Java agent on it. How do I give the JVM options? How to include the agent jar in the deployed jar file? I use Maven to build.
You will have to pass the JVM options as env settings in the application manifest file.
This link provides details on manifest options
- https://docs.cloudfoundry.org/devguide/deploy-apps/manifest.html
And here's an article that has tips for java developers. It has examples on setting memory and other settings for java app.
- https://docs.cloudfoundry.org/buildpacks/java/java-tips.html
To run a spring boot app with a javagent use following jvm option.
-javaagent:<name-of-the-jar>
Use following plugin in your maven project to copy agent jar file on compile.
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.4</version>
<executions>
<execution>
<id>copy</id>

I have webapp which provides web service. I want to perform JUnit tests with SoapUI to check if this service is working properly.
But to test web service application has to be deployed to my Tomcat 7 server.
I have no idea how to configure maven to build war, then deploy it to tomcat (ideally: to run separate tomcat instance for this) and then to run JUnit tests.
I will appreciate any help.
I am using maven 2.2.1
There are a number of schools of thought as to how to handle this type of integration test with Maven.
I should point out that when you are deploying an application to an application server, you are not in the realm of unit testing any more. Because the entire application is being deployed within a container, you are testing the integration of those two components.
Now there is nothing wrong with using JUnit for running integration tests (though there are some limitations that you may hit, for example unit tests should not care about the sequencing of individual tests - assuming you are writing them correctly - so JUnit enforces this by not guaranteeing any sequence of execution... prior to Java 1.7 the execution order was accidentally implied by the order of test methods within a class, but it was not part of the JUnit contract... Some people switch to other testing frameworks for their integration tests, e.g. TestNG, if they find the unit test focus of JUnit is getting in the way of their test development)
The key point to keep in mind is that the Maven lifecycle uses the test phase for the execution of unit tests.
When it comes to integration tests there are two (and a half) schools of thought as to the right way to handle the tests with Maven.
School 1 - Failsafe and integration-test/verify
This school of thought uses the phases after package to start up a container, run the integration tests, tear down the container, and finally check the test results and fail the build in the event of test failures.
NEVER EVER RUN mvn integration-test as that will not tear down the container correctly, any time you think you want to type mvn integration-test you actually want to type mvn verify (oh look, it's shorter and easier to type also... bonus)
So with this you do the following:
Bind tomcat7:run to the pre-integration-test phase with fork=true
Bind failsafe:integration-test to the integration-test phase
Bind tomcat7:shutdown to the post-integration-test phase
Bind failsafe:verify to the verify phase.
For extra brownie points you would use build-helper-maven-plugin:reserve-network-port bound to the validate phase to ensure that the test server is started on an unused network port and then either use resource filtering against the test resources to pass the port through to the tests or use a system property passed through systemPropertyVariables to make the port number available to the tests.
Advantages
Clean Maven build
If the tests fail, you cannot release the project
Can move the integration tests into a separate profile (by convention called run-its) if the tests are too slow to run every build.
Disadvantages
Hard to run the tests from an IDE. All the integration tests start/end in IT and while Maven knows to run tests starting/ending in Test with Surefire and run tests starting/ending in IT with Failsafe, your IDE probably doesn't. Additionally, your IDE is not going to start the container for you, so you have to do a lot of work by hand to actually run the tests manually.
Debugging the tests potentially requires attaching two debuggers, e.g. one to debug the application running in container and the other to debug the test cases.
mvnDebug -Dmaven.failsafe.debug=true verify
Couples your tests to the Maven build process.
School 2 - Separate module
This school of thought moves the integration tests into a separate module that depends on the war module and copies the war into the test resources using, e.g. dependency:copy-dependencies bound to the generate-test-resources phase coupled with a Tomcat7 dependency to test against.
The test cases themselves start up the Tomcat7 container using embedded mode
Advantages
Tests can run in IDE
Integration tests are separated from Unit tests, so asking the IDE to run all tests will not kick off the slower tests
Disadvantages
The war artifact is only rebuilt if you go past the package phase, consequently, you need to run at least mvn clean package periodically to refresh the code under test when using the IDE.
The failure of the integration tests does not break the build of the war module, so you can end up releasing a broken war artifact and then have the reactor build fail for the integration test module. Some people counteract this issue by having the integration test module within src/it and using Maven Invoker Plugin to run the tests... though that provides a poorer IDE integration, so I do not recommend that line.
Hard to get a consolidated test coverage report from Maven.
Have to code the container start/stop yourself from within your test cases.
School 2.5 - Failsafe with the test cases starting their own Tomcat7 server
This is a kind of hybrid of the two approaches.
You use Failsafe to execute the tests, but the tests themselves are responsible for starting and stopping the Tomcat7 container that you want to test in.
Advantages
Don't have to configure the server start/stop in Maven pom
IDE can safely run all tests (though the integration tests may be slower and you may want to not run them, but it's not like they will all fail unless there is a test failure)
Easier to debug the tests from your IDE (only one process to attach against, and the IDE usually makes it easy to debug tests by providing a special test runner)
Disadvantages
Have to code the container start/stop yourself from within your test cases
I hope the above helps you understand the options you have. There may be other tweaks but in general the above are considered the best practice(s) for integration testing with Maven at present.
#Stephen Connolly - your answer above was really good. I thought I'd kick in and show a full configuration for what you termed a School 1 response.
This configuration:
runs unit tests separately from integration tests. It uses the #Category annotation on the root classes that unit tests and integration tests extend.
before integration tests it starts the dependent application (loaded as a maven dependency at runtime) on the local machine, by finding an open port
after integration tests it tears down the dependent application
There's other stuff in there like how to set certain system properties on the dependent application only.
So far this configuration is working awesome..

As Stephen Connolly explains there is no a direct way to configure this. I will explain how to solve this using failsafe plugin. In the maven lifecycle type of test can be tested. Unit testing one of them and another one is integrate testing. Unit testing can be run in the test stage of maven lifecycle. When you want to do integrate test it can be done in verify stage. If you want to know the difference between unit testing and integrate testing, this is a good one. By default unit test classes should be in ***/*Test.java, and **/*TestCase.java this format. The failsafe plugin will look for **/IT*.java, **/*IT.java, and **/*ITCase.java.
Here is an example.
Here I have one unit test class and one integrate test class. Now I will explain, how should be the looks like maven pom.xml. Build section of maven configuration should look like this.
<build>
<plugins>
<plugin>
<artifactId>maven-war-plugin</artifactId>

Unit tests are run before deploying the web app(war file). But integrate tests are run in verify stage. I hope your requirement is satisfied in this stage.
