How to create a single executable war in spring boot

maven, spring-boot

Solution

Thanks to Stephane for suggesting to remove the classifier and for suggesting to use starter.io.

My original problem was I was getting two war files in the target:

- Root.war and the other

- discovery-service-boot.war

I guess, the devil was in the maven-war-plugin config. After I removed the xml tags for warName and outputDirectory, I'm getting the executable war.

I'm posting the final pom.xml to benifit others facing similar situation:

Problem

We are working on spring cloud project using spring boot. Our goal is to create an executable war that can be run using java -jar . I followed couple of posts on SO and was able to generate the executable war by 1) adding "boot" classifier tag in . 2) Adding Repackage goal in execution phase for spring-boot-maven-plugin Now with this approach I'm getting two war files : one war that is not executable but just deployable and another war with boot classifier that suits my requirements Is there a way to just generate only the executable war? I'm attaching the pom.xml for easy reference http://maven.apache.org/xsd/maven-4.0.0.xsd"> 4.0.0 ``` <artifactId>discovery-service</artifactId> <version>1.0.0-SNAPSHOT</version> <packaging>war</packaging> <description> Discovery microservice to provide a service registry using Spring Cloud and Netflix Eureka for cloud native microservices. </description> <properties> <java.version>1.8</java.version> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <version>1.2.3.RELEASE</version> **<configuration> <classifier>boot</classifier> </configuration> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions>** </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <version>2.6</version> <configuration> <failOnMissingWebXml>false</failOnMissingWebXml> <outputDirectory>target</outputDirectory> <warName>ROOT</warName> </configuration> </plugin> </plugins> </build> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka-server</artifactId> </dependency> </dependencies> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Brixton.SR1</version> <type>pom</type> <scope>import</scope> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-parent</artifactId> <version>Brixton.SR1</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> ``` References: One Spring Boot project, deploy to both JAR or WAR Failed to load Main-Class manifest attribute while running java -jar
