Bug#730685:

[Mathieu Malaterre]

Even with an up-to-date libjenkins-trilead-ssh2-java package, the
package cannot be backported to wheezy. It fails with:

dh_install -plibtrilead-putty-extension-java
dh_link -plibtrilead-putty-extension-java
dh_installmime -plibtrilead-putty-extension-java
dh_installgsettings -plibtrilead-putty-extension-java
jh_installlibs -plibtrilead-putty-extension-java
jh_classpath -plibtrilead-putty-extension-java

This happens with a javahelper version 0.45

My guess is that a newer maven-debian-helper should be used (wild guess).
