Почему обработка аннотаций выполняется несколько раз во время сборки maven

В настоящее время я использую обработку аннотаций Java для создания большого количества кода (20 секунд), когда я запускаю mvn process-resources, он запускает apt только один раз, однако, когда я использую mvn package, mvn jetty:run или mvn gwt:run, apt снова запускается после того, как война была упакована. Есть ли способ заставить apt запускаться только один раз?

У меня есть профиль в моем pom.xml

используйте «mvn clean gwt: run -Ppackage» вместо «mvn clean package gwt: run»

Было бы полезно, если бы вы могли опубликовать свой pom, который содержит конфигурацию плагина apt... чтобы увидеть, что происходит. Кроме того, если вы создадите пакет mvn в Maven, будет выполнен полный жизненный цикл, содержащий ресурсы процесса. - khmarbaise 06.06.2012

Я обновил сообщение с подходящей частью моего файла pom, надеюсь, это достаточно ясно - Jiang Zhu 06.06.2012

Вы выполнили команду mvn clean package gwt:run. Maven выполняет жизненный цикл clean (по умолчанию цель clean:clean). Затем он выполняет package, который запускает все цели, связанные с фазой пакета, и все цели, связанные с предыдущими фазами (генерация-источники, процессы-источники, процессы-ресурсы и т. д.). Наконец, он выполняет цель gwt:run. Если вы посмотрите на документацию по цели run, там есть одна очень важная строка:

Вызывает выполнение классов процессов фазы жизненного цикла перед своим выполнением.

Это означает, что Maven снова запустит все цели, связанные с фазой process-classes, и все более ранние фазы. Исполнения подключаемых модулей apt привязаны к фазе generate-sources, поэтому они повторяются, как и ресурсы: ресурсы, компилятор: компиляция и exec:exec, поскольку все они привязаны к фазе process-classes или ранее.

Имея это в виду: работает ли mvn clean gwt:run? Я знаю, что mvn clean jetty:run работает так, как я ожидаю, без дублирования выполнения, но раньше я не использовал gwt.

gwt:run требует, чтобы ресурсы веб-приложения были скопированы в целевую папку, что обычно делается на этапе пакета. Теперь я знаю причину, я могу легко обойти ее, добавив профиль пакета. - Jiang Zhu; 07.06.2012

Почему обработка аннотаций выполняется несколько раз во время сборки maven
