Question

我正在将我的java 6代码升级到java 7.已经更新了JAVA_HOME以指向OS X 10.9上的JDK 1.7。该代码尚未使用任何Java 7功能。

当我运行构建＆＃34; mvn clean install＆＃34;构建中断没有任何有用的错误消息。

构建成功，其中source = 1.6＆amp;目标= 1.6 但失败 for source = 1.7（或7）＆amp; target = 1.7（或7）

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.1</version> <!-- tried with 2.3.2 and 3.0... no luck -->
        <configuration>
          <source>7</source>
          <target>7</target>
          <compilerArgument>-Werror </compilerArgument>
          <fork>true</fork>
        </configuration>

我猜测用JDK 1.7编译你的代码会产生警告，用1.6编译没有。因为你告诉编译器在遇到<compilerArgument>-Werror </compilerArgument>的警告时简单地退出，这正是它正在做的事情，这对Maven不是很友好。我猜Maven吞下原来的警告，支持显示javac进程意外退出的错误。

删除<compilerArgument>-Werror </compilerArgument>指令应允许继续编译。您可能需要处理编译器警告，而不是让编译器退出，可能是通过查看/解析Maven输出。

使用源1.7（或7）的Java maven构建失败
