java - Maven: 包 com.sun.istack.internal 不存在

Question

我有一个使用 com.sun.istack.internal.Nullable 的小 maven 项目。
我尝试了 JDK 9 和 1.8，但仍然收到关于包不存在的错误。我搜索包裹并找到一些:https://mvnrepository.com/search?q=+com.sun.istack但他们仍然没有提供必要的。

JAVA_HOME:

apshenichnikov@IAS-WS-UX02:~/NetBeansProjects/newlps$ echo $JAVA_HOME
/usr/local/java/jdk1.8.0_121/

和 JDK:

apshenichnikov@IAS-WS-UX02:~/NetBeansProjects/newlps$ sudo update-alternatives --config java
There are 4 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                     Priority   Status
------------------------------------------------------------
  0            /usr/lib/jvm/java-9-oracle/bin/java       1091      auto mode
  1            /usr/lib/jvm/java-8-oracle/jre/bin/java   1081      manual mode
  2            /usr/lib/jvm/java-9-oracle/bin/java       1091      manual mode
* 3            /usr/local/java/jdk1.8.0_121/             1         manual mode
  4            /usr/local/java/jdk1.8.0_121/bin/java     1         manual mode

我注入(inject)了:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.0</version>
    <configuration>
        <compilerArgument>-XDignore.symbol.file</compilerArgument>
    </configuration>
</plugin>

在 POM.xml 中

而且我仍然有编译异常

Answer 1

改为尝试导入 import org.jetbrains.annotations.Nullable。它与 @Nullable 注释相同。

然后添加这个依赖:

<dependency>
    <groupId>org.jetbrains</groupId>
    <artifactId>annotations</artifactId>
    <version>13.0</version>
</dependency>
