Сборка Eclipse PDE не может найти местоположение jar на customAssembly

Я запускаю сборку PDE - почти по умолчанию (см. в конце сообщения), которая копирует все мои плагины/функции, разрешает их, компилирует и генерирует метаданные p2.

На шаге customAssembly он загадочно терпит неудачу с

Как ни странно, в каталоге /tmp/eclipse.build/tmp/eclipse/plugins/ есть файл jar:

/tmp/eclipse.build/tmp/eclipse/plugins/javax.xml.soap_1.3.0.v200904281458.jar

Я не в курсе, так как это должен быть полностью автоматический процесс, но все же он загадочным образом терпит неудачу.

Любые идеи?
