Maven：無効なターゲットリリース：10

maven プロジェクトを Java 10 を使用してコンパイルしようとしていますが、問題があります。私のIDE（IntelliJ IDEA）では、すべてがJava 10の下で正常にコンパイルおよび実行されます。最新のmavenバージョン3.5.4をインストールし、Java_HOMEをJDK 10にポイントしました。

$ mvn --version
Apache Maven 3.5.4 (1edded0938998edf8bf061f1ceb3cfdeccf443fe; 2018-06-17T20:33:14+02:00)
Maven home: C:\Maven\bin\..
Java version: 10.0.2, vendor: Oracle Corporation, runtime: C:\Program Files\Java\jdk-10.0.2
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 10", version: "10.0", Arch: "AMD64", family: "windows"

私が使用するmavenコマンドは次のとおりです。

mvn package -Dmaven.test.skip

pom.xmlには、Java 8に対して次のものがあり、うまくいきました。

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
    <libraries.directory>libraries</libraries.directory>
</properties>

Java 10については、次のように変更しました。

<maven.compiler.source>10</maven.compiler.source>
<maven.compiler.target>10</maven.compiler.target>

これは、ソースコンパイラとターゲットコンパイラのバージョンとして1.10を使用するのと同じように機能しません。

完全なデバッグログ出力（-Xコマンドラインスイッチ）は次のとおりです。

this answerで提案されているようなmaven-compiler-pluginを追加しても機能しません：

Fatal error compiling: invalid flag: --release -> [Help 1]

この問題を修正する方法についてのアイデアはありますか？

これは私のために働いた：

<build>
    <plugins>
        <plugin>
            <groupId>org.Apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.7.0</version>
            <configuration>
                <release>10</release>
            </configuration>
        </plugin>
    </plugins>
</build>

これは answer が必要だということです：

<dependencies>
    <dependency>
        <groupId>org.ow2.asm</groupId>
        <artifactId>asm</artifactId>
        <version>6.2</version> <!-- Use newer version of ASM -->
    </dependency>
</dependencies>

<plugin/>タグ内にありますが、新しいmvn（3.5.4）では不要であるため、これを回避する必要があります。

Java -versionを実行して、Javaバージョンを取得します。

次のような出力が得られます。

Java version "1.8.0_201"

POMファイルに移動し、maven-compiler-pluginのソースとターゲットのプロパティを、インストール済みのJavaバージョンで更新します。私の場合は1.8です

<plugin>
   <groupId>org.Apache.maven.plugins</groupId>
   <artifactId>maven-compiler-plugin</artifactId>
   <configuration>
      <source>1.8</source>
      <target>1.8</target>
   </configuration>
</plugin>
