作為Maven軟件包運行時編譯失敗

Question

當我作為Maven軟件包運行時出現此BUILD錯誤。 但是我不確定是什么錯誤。 有人可以幫忙嗎？ 提前致謝。

Answer 1

“錯誤：-source 1.3中不支持泛型”

我猜你的代碼使用泛型，編譯器被告知使用不支持此類的java 1.3。

編輯：您可能必須至少使用java 1.5

 <project>
 [...]
   <build>
   [...]
   <plugins>
     <plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-compiler-plugin</artifactId>
     <version>2.3.2</version>
     <configuration>
       <source>1.5</source>
       <target>1.5</target>
     </configuration>
   </plugin>
  </plugins>
  [...]
  </build>
 [...]
 </project>

Answer 2

將此添加到您的Maven POM：

<build>
  [...]
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>2.3.2</version>
        <configuration>
          <!-- set compliance level here -->
          <source>1.6</source>
          <target>1.6</target>
        </configuration>
      </plugin>
    </plugins>
  [...]
</build>

順便說一句，當前版本的Maven假定1.5為默認遵從級別。 也許您應該升級到當前的Maven版本。
