java - 是什么导致 "an unknown compilation problem occurred"？

Question

尝试使用 Maven 编译我的项目时，我收到以下错误:An unknown compilation problem occurred .

我尝试运行以下命令以获取有关错误的更多详细信息，但我仍然无法弄清楚:mvn -e -X clean install
这是我得到的日志:

编辑:这是 pom.xml data-access 的文件模块:

编辑 2:根目录上的 Maven 编译器插件配置 pom.xml :

...

<properties>
  <maven-compiler-plugin.version>3.1</maven-compiler-plugin.version>
  <java.version>11</java.version>
</properties>

...

<plugin>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>${maven-compiler-plugin.version}</version>
  <configuration>
    <source>${java.version}</source>
    <target>${java.version}</target>
  </configuration>
</plugin>

...

需要注意的是，这个编译问题是在我将项目中的 Java 版本从 1.8 迁移到 11 之后开始出现的。

Answer 1

我面临同样的问题。删除后我能够摆脱这个问题
-Werror
pom.xml 文件中 maven 编译器插件配置的行。
删除上述行之前的 maven-compiler-plugin 配置:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.3</version>
    <configuration>
        <encoding>UTF-8</encoding>
        <source>1.8</source>
        <target>1.8</target>
        <compilerArgument>-Werror</compilerArgument>
    </configuration>
</plugin>

删除以上行后的 maven-compiler-plugin 配置:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.3</version>
    <configuration>
        <encoding>UTF-8</encoding>
        <source>1.8</source>
        <target>1.8</target>
    </configuration>
</plugin>
