Java/Maven compilation failure (no suitable constructor found) -

-

i ran strange problem..
work on project use processbuilder class.
on local machine (java6 , java7 tested) can mvn clean install & mvn assembly:single project without errors. want let project build travis-ci , ran following error

error: no suitable constructor found processbuilder(string)

full log file here.. javadoc processbuilder show me constructor.
.travis.yml looks this

language: java

jdk:
- oraclejdk7
- openjdk6
- openjdk7

after_success:
- mvn assembly:single

any ideas why build fails on travis-ci?

thanks, f481

edit:
locally i'm using maven 3, travis-ci (travis doc: "travis java builder use maven 3 build it.") pom.xml: https://github.com/multiservercontrol/minecontrol/blob/master/pom.xml
, java code of first error: this.processbuilder = new processbuilder("");
full class available here

edit2: specified source , target version maven compilation this:

<plugin>       <groupid>org.apache.maven.plugins</groupid>       <artifactid>maven-compiler-plugin</artifactid>       <version>3.0</version>       <configuration>           <source>1.7</source>           <target>1.7</target>       </configuration> </plugin>

now build working jdk7: https://travis-ci.org/multiservercontrol/minecontrol/jobs/5963859

but don't reason behavior.. , want build project jdk 5,6 too.
how can that?

i specified version of maven compiler plugin , source , target version compilation this:

<plugin>       <groupid>org.apache.maven.plugins</groupid>       <artifactid>maven-compiler-plugin</artifactid>       <version>3.0</version>       <configuration>           <source>1.5</source>           <target>1.5</target>       </configuration> </plugin>

now build working! nilsh pushed me in right direction.
