Я получил NullPointerException с помощью maven-compiler-plugin: 3.1. Я рассмотрел аналогичные вопросы по SOF, но тщетно пытался.maven-compiler-plugin: 3.1: сбой компиляции. NullPointerException
Команда, я побежал: mvn compile
The Maven среда:
Apache Maven 3.0.3 (rNON-CANONICAL_2011-12-28_13-22_mein; 2011-12-28 13:22:36-0600)
Maven home: /soft/maven/3.0.3
Java version: 1.6.0_38, vendor: Sun Microsystems Inc.
Java home: /soft/jdk1.6.0_38-arch/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.13.0-83-generic", arch: "amd64", family: "unix"
(Она использует 1.6, так как это требуется по проекту, наследие проекта)

3.1 довольно старый. Используйте последнюю версию 3.5.1 и попытайтесь опубликовать [mcve] проблемы. – Tunaki
Не используйте Maven 3.0.3, который действительно багги .. используйте более uptodate версию, такую как 3.3.9 ... – khmarbaise
