jdk.internal.reflect包不可見java
java9模塊化以後,java.base只把jdk.internal.reflect暴露給了少數幾個內部包而沒有向當前模塊暴露。apache
alt+enter IDEA會自動提示解決方案,它的解決方案只針對.idea/compiler.xml。即使直接運行程序不報錯,在執行mvn compile時也會報錯,說jdk.internal.reflect不可見。maven
<component name="JavacSettings"> <option name="ADDITIONAL_OPTIONS_OVERRIDE"> <module name="hanlp" options="--add-exports=java.base/jdk.internal.reflect=ALL-UNNAMED,hanlp" /> </option> </component>
須要進一步更改compiler插件的命令行參數ide
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.1</version> <configuration> <source>12</source> <target>12</target> <encoding>utf-8</encoding> <showDeprecation>true</showDeprecation> <showWarnings>true</showWarnings> <compilerArgument> --add-exports=java.base/jdk.internal.reflect=ALL-UNNAMED,hanlp </compilerArgument> </configuration> </plugin>
