java - Spring boot and maven exec plugin issue -

-

i've created bare-bone maven project, empty except pom.xml.

with pom (note parent element commented-out):

<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">   <modelversion>4.0.0</modelversion>   <groupid>springboot-test</groupid>   <artifactid>springboot-test</artifactid>   <version>1.0.0-snapshot</version>  <!--    <parent> --> <!--        <groupid>org.springframework.boot</groupid> --> <!--        <artifactid>spring-boot-starter-parent</artifactid> --> <!--        <version>1.1.9.release</version> --> <!--    </parent> -->    <build>     <plugins>       <plugin>         <artifactid>maven-compiler-plugin</artifactid>         <version>3.2</version>         <configuration>           <source>1.7</source>           <target>1.7</target>         </configuration>       </plugin>     </plugins>   </build>  </project>

sample run:

this expected (there's no clas test in project).

using pom (i.e. un-commenting parent):

<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">   <modelversion>4.0.0</modelversion>   <groupid>springboot-test</groupid>   <artifactid>springboot-test</artifactid>   <version>1.0.0-snapshot</version>    <parent>     <groupid>org.springframework.boot</groupid>     <artifactid>spring-boot-starter-parent</artifactid>     <version>1.1.9.release</version>   </parent>    <build>     <plugins>       <plugin>         <artifactid>maven-compiler-plugin</artifactid>         <version>3.2</version>         <configuration>           <source>1.7</source>           <target>1.7</target>         </configuration>       </plugin>     </plugins>   </build>  </project>

same thing happens exec-maven-plugin:1.3.2:

$ mvn org.codehaus.mojo:exec-maven-plugin:1.3.2:java -dexec.mainclass=test [info] scanning projects...

additional information:

$ java -version java version "1.8.0_11" java(tm) se runtime environment (build 1.8.0_11-b12) java hotspot(tm) 64-bit server vm (build 25.11-b03, mixed mode) $ mvn -v apache maven 3.2.2 (45f7c06d68e745d05611f7fd14efb6594181933e; 2014-06-17t09:51:42-04:00) maven home: c:\dev\bin\apache-maven-3.2.2 java version: 1.8.0_11, vendor: oracle corporation java home: c:\progra~1\java\jdk1.8.0_11\jre default locale: en_us, platform encoding: cp1252 os name: "windows 7", version: "6.1", arch: "amd64", family: "dos"

questions:

  • why failing / how fix?
  • why failing when parent added? how exec-maven-plugin influenced this?

(as side note, love fact windows 7 belongs faimly: "dos", i'm waiting family: "cp/m" implemented windows 8.1)

its because spring-boot adding maven configuration project. if using eclipse, there's tab called: 'effective pom'.

from tab can see adds snippet below:

    <plugin>       <groupid>org.codehaus.mojo</groupid>       <artifactid>exec-maven-plugin</artifactid>       <version>1.2.1</version>       <configuration>         <mainclass>${start-class}</mainclass>       </configuration>     </plugin>

so when run spring-boot parent, looks value of ${start-class}, resolves empty unless defined it, that's when see error not having value mainclass parameter.

add project:

<properties>     <start-class>com.test</start-class> </properties>

then run it: clean compile exec:java

 [info] --- exec-maven-plugin:1.2.1:java (default-cli) @ springboot-test --- **********test************** [info] ------------------------------------------------------------------------ [info] build success [info] ------------------------------------------------------------------------ [info] total time: 2.388 s [info] finished at: 2014-12-05t15:25:05-06:00 [info] final memory: 17m/231m [info] ------------------------------------------------------------------------

you can provide value start-class property on command line, works if didn't define inside pom file:

mvn exec:java -dstart-class=com.test
