我正在尝试将我的 SpringBoot maven 项目更新为 Java17.
<maven.compiler.source>17</maven.compiler.source>
<maven.compiler.target>17</maven.compiler.target>
我定义了工作 maven-jaxb2-plugin 插件，它从 XSD 个文件成功创建 java 类。
<plugin>
<groupId>org.jvnet.jaxb2.maven2</groupId>
<artifactId>maven-jaxb2-plugin</artifactId>
<version>0.14.0</version>
<executions>
<execution>
<id>my_schema</id>
<phase>generate-sources</phase>
<goals>
<goal>generate</goal>
</goals>
<configuration>
<schemaDirectory>src/main/resources/my/files</schemaDirectory>
<schemaIncludes>
<include>*.xsd</include>
</schemaIncludes>
<bindingDirectory>src/main/resources/my/files</bindingDirectory>
<bindingIncludes>
<include>bindings.xml</include>
</bindingIncludes>
<args>
<arg>-extension</arg>
<arg>-Xnamespace-prefix</arg>
</args>
</configuration>
</execution>
</executions>
</plugin>
但是由于升级了java和插件，我无法做到。
我为插件定义了必要的依赖项：
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-core</artifactId>
<version>3.0.2</version>
</dependency>
<dependency>

但是我在构建 Maven 的过程中仍然收到一个未知错误：

而且我在网上找不到任何有用的提示。谁能帮我解决这个问题？
它编译，当你添加jaxb-runtime依赖时，如下：
<build>
<plugins>
<plugin>
<groupId>org.jvnet.jaxb2.maven2</groupId>
<artifactId>maven-jaxb2-plugin</artifactId>
<version>0.14.0</version>
<dependencies>
<dependency>
<groupId>org.glassfish.jaxb</groupId>
<artifactId>jaxb-runtime</artifactId>
<version>${jaxb-api.version}</version>
</dependency>
注意，我没有关闭所有打开的标签，因为这些与问题无关。这些只是为了清楚地将 jaxb-runtime 依赖项放在哪里而开放。
我用的是2.3.1版本，编译成功
我在将我的项目和库从 java 16 迁移到 java 17 时收到类似的错误消息。我使用的是 -illegal-access=permit 选项，它在 java 17. 以上回答没有解决我的问题。我的情况是这样的。我有一个库（假设是 x）和一个应用程序（假设是 y）。应用程序 y 使用库 x。我在库x中添加了以下依赖，问题就解决了。
<dependency>
<groupId>org.glassfish.jaxb</groupId>
<artifactId>jaxb-runtime</artifactId>
<version>2.3.1</version>
</dependency>
但是如果我直接将这个依赖添加到应用程序y而不是库x中，问题就无法解决
我正在尝试将我的 SpringBoot maven 项目更新为 Java17.

而且我在网上找不到任何有用的提示。谁能帮我解决这个问题？
它编译，当你添加jaxb-runtime依赖时，如下：
<build>
<plugins>
<plugin>
<groupId>org.jvnet.jaxb2.maven2</groupId>
<artifactId>maven-jaxb2-plugin</artifactId>
<version>0.14.0</version>
<dependencies>
<dependency>
<groupId>org.glassfish.jaxb</groupId>
<artifactId>jaxb-runtime</artifactId>
<version>${jaxb-api.version}</version>
</dependency>
注意，我没有关闭所有打开的标签，因为这些与问题无关。这些只是为了清楚地将 jaxb-runtime 依赖项放在哪里而开放。 我用的是2.3.1版本，编译成功
我在将我的项目和库从 java 16 迁移到 java 17 时收到类似的错误消息。我使用的是 -illegal-access=permit 选项，它在 java 17. 以上回答没有解决我的问题。我的情况是这样的。我有一个库（假设是 x）和一个应用程序（假设是 y）。应用程序 y 使用库 x。我在库x中添加了以下依赖，问题就解决了。
<dependency>
<groupId>org.glassfish.jaxb</groupId>
<artifactId>jaxb-runtime</artifactId>
<version>2.3.1</version>
</dependency>
但是如果我直接将这个依赖添加到应用程序y而不是库x中，问题就无法解决
