Running main method from test class via maven -


i have following in pom.xml:

<build>    ...    <plugins>    ...       <plugin>           <groupid>org.codehaus.mojo</groupid>           <artifactid>exec-maven-plugin</artifactid>           <version>1.2.1</version>           <configuration>               <mainclass>com.myorg.myclass</mainclass>           </configuration>       </plugin>    </plugins> </build>

the class com.myorg.myclass in test source directory, , able run following command:

mvn -e exec:java -dexec.classpathscope="test"

i want to:

  1. avoid having use -dexec.classpathscope="test", cannot work out how configure plugin in test classpath.
  2. write more plugins other classes (which each have different configurations), right can run exec:java. there way label plugin call via label rather "run whatever in exec:java"?
  3. pull in -javaagent property. have property defined in pom.xml, being used test cases. "custom" plugin pick these properties or need pull them in?

here properties, defined directly under <project>.

<properties>    <spring.version>3.2.6.release</spring.version>    <atomikos.version>3.9.2</atomikos.version>    <loadtimeweaverargline>-javaagent:"${settings.localrepository}/org/springframework/spring-agent/2.5.6/spring-agent-2.5.6.jar"</loadtimeweaverargline> </properties>

attempt profile

following on @michal's suggestion (https://stackoverflow.com/a/30839824/257233) have tried:

<profile>    <id>run-importer</id>    <properties>       <loadtimeweaverargline>-javaagent:"${settings.localrepository}/org/springframework/spring-agent/2.5.6/spring-agent-2.5.6.jar"</loadtimeweaverargline>    </properties>    <build>       <plugins>          <plugin>             <groupid>org.codehaus.mojo</groupid>             <artifactid>exec-maven-plugin</artifactid>             <version>1.2.1</version>             <configuration>                <executable>java</executable>                   <!--                      none of these 3 options work.                      <commandlineargs>-javaagent:c:/users/robbram/.m2/repository/org/springframework/spring-agent/2.5.6/spring-agent-2.5.6.jar</commandlineargs>                      <commandlineargs>${loadtimeweaverargline}</commandlineargs>                      <commandlineargs>-javaagent:"${settings.localrepository}/org/springframework/spring-agent/2.5.6/spring-agent-2.5.6.jar"</commandlineargs>                      <argline>${loadtimeweaverargline}</argline>                   -->                <classpathscope>test</classpathscope>                <mainclass>com.myorg.myclass</mainclass>             </configuration>          </plugin>       </plugins>    </build> </profile>

i run with:

mvn -e exec:java -prun-importer

i getting following exception either of options:

[error] failed execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:java (default-cli) on project toltat-model: exception occured while executing java class. null: invocationtargetexception: error creating bean name 'loadtimeweaver' defined in class org.springframework.context.annotation.loadtimeweavingconfiguration: instantiation of bean failed; nested exception org.springframework.beans.factory.beandefinitionstoreexception: factory method [public org.springframework.instrument.classloading.loadtimeweaver org.springframework.context.annotation.loadtimeweavingconfiguration.loadtimeweaver()] threw exception; nested exception java.lang.illegalstateexception: classloader [java.net.urlclassloader] not provide 'addtransformer(classfiletransformer)' method. specify custom loadtimeweaver or start java virtual machine spring's agent: -javaagent:org.springframework.instrument.jar -> [help 1] org.apache.maven.lifecycle.lifecycleexecutionexception: failed execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:java (default-cli) on project toltat-model: exception occured while executing java class. null    @ org.apache.maven.lifecycle.internal.mojoexecutor.execute(mojoexecutor.java:216)    @ org.apache.maven.lifecycle.internal.mojoexecutor.execute(mojoexecutor.java:153)    @ org.apache.maven.lifecycle.internal.mojoexecutor.execute(mojoexecutor.java:145)

i can confirm main class com.myorg.myclass being executed. can see other output it. can confirm loadtimeweaverargline works in other parts of pom. used integration tests: 

<profile>    <id>integration-tests</id>    <build>       <plugins>          <!-- integration tests require additional loadtime spring argument -->          <plugin>             <groupid>org.apache.maven.plugins</groupid>             <artifactid>maven-surefire-plugin</artifactid>             <version>2.16</version>             <configuration>                <forkmode>once</forkmode>                <argline> ${loadtimeweaverargline}</argline>                <skip>false</skip>             </configuration>          </plugin>       </plugins>    </build> </profile>

attempt 2 profile , mvn exec:exec

upodate (wednesday, 17th of june 2015, 12:11:17 pm): following on michal's latest comment have working want:

<profile>    <id>run-importer</id>    <properties>       <loadtimeweaverarg>-javaagent:"${settings.localrepository}/org/springframework/spring-agent/2.5.6/spring-agent-2.5.6.jar"</loadtimeweaverarg>       <log4jconfigarg>-dlog4j.configuration=file:${project.build.directory}/path/to/log4j.properties</log4jconfigarg>       <mainclassarg>com.myorg.myclass</mainclassarg>       <arg1>foo</arg1>    </properties>    <build>       <plugins>          <plugin>             <groupid>org.codehaus.mojo</groupid>             <artifactid>exec-maven-plugin</artifactid>             <version>1.2.1</version>             <goals>                <goal>exec</goal>             </goals>             <configuration>                <executable>java</executable>                <classpathscope>test</classpathscope>                <arguments>                   <argument>${log4jconfigarg}</argument>                   <argument>${loadtimeweaverarg}</argument>                   <argument>-classpath</argument>                   <classpath />                   <argument>${mainclassarg}</argument>                   <argument>${arg1}</argument>                </arguments>             </configuration>          </plugin>       </plugins>    </build> </profile>

and run with:

mvn -e exec:exec -prun-importer

the advantages of approach:

  • the whole purpose of profile run "special code" should never deployed needs make use of code in src , test src.
    • i note michal's suggestion deserves module itself. if code base wasn't established (large, old, complicated), consider this.
  • it leaves room in case ever needs duplicated, there no "competition" regarding gets run mvn -e exec:exec.
  • i can specify java agent, log4j , lots of other config using variables exist in pom.
  • i can override of these arguments on command line -darg1="bar"

i'm not sure you're going accomplish since it's quite stilted use of maven. however, stuff technically possible:

1/

<plugin>     <groupid>org.codehaus.mojo</groupid>     <artifactid>exec-maven-plugin</artifactid>     <version>1.2.1</version>     <configuration>         <mainclass>com.myorg.myclass</mainclass>         <classpathscope>test</classpathscope>     </configuration> </plugin>

2/

you can use profiles , put different plugin configurations in different profile. call:

mvn -e exec:java -pmy-first-profile

it's weird however, think. recommendation here reconsider case , maybe pick way or tool that.

3/

final solution in question after author's edit.

i have method allows user access comment have made on site. have post method lets them update comment. my normal solution send entire comment model through, let them update it, update on database when post back. involve sending commentid through in hiddenfor , can manipulated. how can verify commentid sent in get method same i'm getting in post , not able alter comment wish? how can verify commentid sent in method same i'm getting in post? basically have validate following things in post - user logged-in user. authenticated users post comments. commentid in post , should valid commentid , should present in database. userid associated logged-in user should same userid associated comment . comment should contain userid column, can check @ time of update. to make sure update happens comment has been sent in get - hold commentid in session , in post action compare commentid value in session .
