私は Helidon MP を初めて使用し、ファイル読み取り用のロジックを書き込もうとしているときにエラーが発生しました。以下は同じ詳細です。

コンパイル エラー:

タイプ io.helidon.media.common.MessageBodyReadableContent を解決できません。必要な .class ファイルから間接的に参照されている

コード/ロジック

@Path("/list/upload")
@POST
@Produces(MediaType.APPLICATION_JSON)
public void uploadHeaders(ServerRequest req, ServerResponse res) {
        
        
        req.content().as(MultiPart.class).thenAccept(multiPart -> {
            for(BodyPart bodyPart : multiPart.bodyParts()){
                String content = bodyPart.as(String.class);
                System.out.println("Part:\n" + content);
            }
        });
    }

Helidon BOM (別名Bill-of-Material )を使用しているため、サブモジュール (helidon-media-xxxこの場合) の明示的なバージョンを宣言しないでください。そうしないと、直面している非互換性の問題に陥ります。

あなたのdependencyManagementセクションではhelidon-bom、POMインポートとして宣言しました：

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>io.helidon</groupId>
            <artifactId>helidon-bom</artifactId>
            <version>${helidon.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
        <!-- Other dependencies -->
</dependencyManagement>

はhelidon.version、すべてのアーティファクトに対して宣言された唯一のバージョンである必要がありhelidon-xxxます (具体的なアーティファクトのバージョンは内部で異なる可能性がありますが、それは BOM 自体内で管理されるため、それで遊ぶべきではないことに注意してください)。

helidon-xxxすべてのアーティファクト バージョンを省略した依存関係セクションは次のようになります。
