我正在尝试让 Maven 为某些遗留代码调用 ANT 构建。 ant 构建通过 ant 正确构建。但是,当我使用 Maven ant 插件调用它时,它失败并出现以下错误:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.6:run (default) on project CoreServices: An Ant BuildException has occured: The following error occurred while executing this line:
[ERROR] C:\dev\projects\build\build.xml:158: The following error occurred while executing this line:
[ERROR] C:\dev\projects\build\build.xml:62: The following error occurred while executing this line:
[ERROR] C:\dev\projects\build\build.xml:33: The following error occurred while executing this line:
[ERROR] C:\dev\projects\ods\build.xml:41: Unable to find a javac compiler;
[ERROR] com.sun.tools.javac.Main is not on the classpath.
[ERROR] Perhaps JAVA_HOME does not point to the JDK.
[ERROR] It is currently set to "C:\bea\jdk150_11\jre"
我的 javac 存在于 C: ea\jdk150_11 中,这适用于所有其他事情。我不确定 Maven 从哪里获取此版本的 JAVA_HOME。 windows环境变量中的JAVA_HOME设置为C:ea\jdk150_11\,应该是这样。
我用来调用 build.xml 的 Maven 代码是
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.6</version>
<executions>
<execution>
<phase>install</phase>
<configuration>
<target>
<ant antfile="../build/build.xml" target="deliver" >
</ant>
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
第一件事:为什么在
install
阶段而不是在 compile
阶段执行 ANT 脚本?
第二件事:你的问题可能是由于Maven执行JRE而不是JDK而引起的,尽管你的JAVA_HOME指向JDK。要解决此问题,您必须手动调整 maven-antrun-plugin 的依赖关系。这只是一个例子:
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.6</version>
<dependencies>
<dependency>
<groupId>com.sun</groupId>
<artifactId>tools</artifactId>
<version>1.5.0</version>
<scope>system</scope>
<systemPath>${java.home}/../lib/tools.jar</systemPath>
</dependency>
</dependencies>
<executions>
<execution>
<phase>compile</phase>
<configuration><target><ant/></target></configuration>
<goals><goal>run</goal></goals>
</execution>
</executions>
</plugin>
我和OP有同样的问题!
解决方案:在ant
<javac>
命令中,设置其标志:fork=yes
<target name="compileJava">
<javac destdir="${dir.build}"
fork="yes"
includeantruntime="false"
debug="true"
failonerror="true">
//...
</javac>
</target>
