无法在 Ubuntu 16.04 上编译 java

Question

由于我升级到全新安装的 Ubuntu 16.04，我无法使用任何已安装的 JDK 编译我的 Java 项目，例如这个：

$ 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-8-oracle/jre/bin/java          1082      auto mode
  1            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1081      manual mode
  2            /usr/lib/jvm/java-8-oracle/jre/bin/java          1082      manual mode
* 3            /usr/lib/jvm/jdk1.8.0_65/bin/java                100       manual mode
  4            /usr/lib/jvm/jdk1.8.0_92/bin/java                100       manual mode

编译我的 maven 项目：

$ mvn clean install -DskipTests

我安装的其他 Java 版本也会发生同样的错误。 使用 Maven 3.3.9

在远程机器上使用 Ubuntu 12.04 和 java build 1.8.0_91-8u91-b14-0ubuntu4~12.04-b14 进行了尝试，没有编译错误。用 java 1.8.0_91-8u91-b14-3ubuntu1~16.04.1-b14 在我的 16.04 上尝试了最接近的东西，得到与上述相同的错误。

通过 mvn compile 会导致不同阶段的细分，但 mvn package 会导致错误。

Answer 1

这是 maven-compiler-plugin 的 3.2 和 3.3 版本中的一个错误。

第二次运行'mvn package'时，之前生成的源码目录在generate-source阶段之前被添加到源码路径中，导致这个解析器异常。

以 maven-compiler-plugin 为例，切换回较旧的 3.2 版 即可解决此问题。

请注意，增量编译在 maven-compiler-plugin 的 3.0 和 3.1 版本中被破坏。所以，我更喜欢切换 2.5.1 版本的 maven-compiler-plugin。
