由于缺少tools.jar,Maven AspectJ插件无法使用Java 9构建

Question

我将JDK版本从8切换到9,由于缺少tools.jar,AspectJ插件不再有效:

目标org.codehaus.mojo的执行默认值:aspectj-maven-plugin:1.10:编译失败:插件org.codehaus.mojo:aspectj-maven-plugin:1.10或其中一个依赖项无法解析:找不到工件com .sun:tools:jar:9.0.1在指定路径C:\ Program Files\Java\jdk-9.0.1 /../ lib/tools.jar

我知道从Java 9 JDK中删除了tools.jar(和rt.jar).我想知道是否有办法让Maven AspectJ插件在没有tools.jar的情况下使用Java 9？

这是我的插件定义版本信息:

    <plugin>
      <groupId>org.codehaus.mojo</groupId>
      <artifactId>aspectj-maven-plugin</artifactId>
      <version>1.10</version>
      <configuration>       
      <encoding>${project.build.sourceEncoding}</encoding>
      <complianceLevel>1.9</complianceLevel>
      <showWeaveInfo>true</showWeaveInfo>
      <XnoInline>true</XnoInline>         
      </configuration>
      <executions>
        <execution>
          <goals>
            <goal>compile</goal>
              <goal>test-compile</goal>
          </goals>
        </execution>
      </executions>     
      <dependencies>
       <dependency>

      </dependency> 
      <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjtools</artifactId>
        <version>1.9.0.RC2</version>
       </dependency>          
      </dependencies>
    </plugin>

我刚刚发现了一个让aspectj 与Java 9 一起工作的丑陋技巧，只需将com.sun:tools 指向pom.xml，编译器就会运行。

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>aspectj-maven-plugin</artifactId>
    <version>1.11</version>
    <executions>
        <execution>
            <goals>
                <goal>compile</goal>
                <goal>test-compile</goal>
            </goals>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
                <complianceLevel>1.8</complianceLevel>
                <encoding>UTF-8</encoding>
                <verbose>true</verbose>
                <weaveDependencies>
                    <weaveDependency>
                        <groupId>io.grpc</groupId>
                        <artifactId>grpc-netty</artifactId>
                    </weaveDependency>
                </weaveDependencies>
                <showWeaveInfo>true</showWeaveInfo>
                <XnoInline>true</XnoInline>
            </configuration>
        </execution>
    </executions>
    <dependencies>
        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjrt</artifactId>
            <version>${aspectj.version}</version>
        </dependency>
        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjtools</artifactId>
            <version>${aspectj.version}</version>
        </dependency>
        <dependency>
            <groupId>com.sun</groupId>
            <artifactId>tools</artifactId>
            <version>${java.version}</version>
            <scope>system</scope>
            <systemPath>${project.basedir}/pom.xml</systemPath>
        </dependency>
    </dependencies>
</plugin>

在使用快照版本代替将版本1.11.1发布到Maven Central之前：org.codehaus.mojo

            <groupId>com.github.m50d</groupId>
            <artifactId>aspectj-maven-plugin</artifactId>
            <version>1.11.1</version>

你检查过最新的插件版本吗？

<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>
<version>1.11</version>
