Я обновляю свой проект с java 8 до java 11. Я могу собрать и развернуть его с зависимостями java11, spring 5, но когда я добавляю информацию о модуле. java в свой проект, я я получаю ошибку ниже при сборке:

Я добавил maven-compiler-plugin, как показано ниже в моем файле pom: 

<properties>
    <java.version>11</java.version>
    <maven.compiler.source>${java.version}</maven.compiler.source>
    <maven.compiler.target>${java.version}</maven.compiler.target>
    <maven.compiler.release>${java.version}</maven.compiler.release>
 </properties>

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.0</version>
    <configuration>
        <release>${java.version}</release>
        <source>${java.version}</source>
        <target>${java.version}</target>
    </configuration>
</plugin>

Пожалуйста, помогите мне, если я делаю что-то не так.

Это ошибка в Maven-Compiler-Plugin

Посмотрите на следующие вопросы: https://issues.apache.org/jira/browse/MCOMPILER-355 https://issues.apache.org/jira/browse/MCOMPILER-359

специально для номера строки CompilerMojo.java:244

Caused by: java.lang.NullPointerException
 at org.apache.maven.plugin.compiler.CompilerMojo.preparePaths (CompilerMojo.java:244)

MCOMPILER-355 исправлен в версии 3.8.1 . Исправление MCOMPILER-359 будет частью следующего выпуска https://github.com/apache/maven-compiler-plugin/pull/28/files

Вам следует попробовать обновить версию Maven-Compiler-Plugin до 3.8.1 .
