使用Maven為Openshift建立錯誤

Question

這是我的POM.xml文件

當我使用mvn軟件包進行構建時

可能是什么問題？

Answer 1

我的小組項目遇到了同樣的問題。 特別是，這行破壞了您的構建：

<maven.compiler.executable>${env.OPENSHIFT_WILDFLY_DIR}usr/lib/jvm/jdk1.8.0_05/bin/javac</maven.compiler.executable>

它指定javac編譯Java文件的路徑。 但是，上面的這一行指向固定路徑（並非在所有計算機上都相同）。 刪除它，您的本地版本將通過。 但是，我懷疑如果刪除該行，可能會在openshift端破壞某些內容。
