Question

我尝试用maven构建一个java项目。我使用java 7但是maven源是1.6。我无法改变它。当我运行“mvn clean install”时，它失败并出现一个奇怪的错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project search: Compilation failure
[ERROR] could not parse error message: warning: [options] bootstrap class path not set in conjunction with -source 1.6
[ERROR] /someClassName.java:114: warning: [deprecation] LUCENE_36 in Version has been deprecated
[ERROR] out = new ICUCollationKeyAnalyzer(Version.LUCENE_36, l);
[ERROR] ^
[ERROR] -> [Help 1]
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project search: Compilation failure
could not parse error message: warning: [options] bootstrap class path not set in conjunction with -source 1.6
/someClassName.java:114: warning: [deprecation] LUCENE_36 in Version has been deprecated
                    out = new ICUCollationKeyAnalyzer(Version.LUCENE_36, l);

目前，我不会像maven推荐的那样更改lucene版本。所以，我想知道为什么maven关心代码中弃用的东西以及如何避免这些错误？感谢。

Apache Maven 3.0.4
Java version: 1.7.0_25, vendor: Oracle Corporation

Answer 1

错误消息具有误导性 - 它只是编译警告，而不是失败。这可能与http://jira.codehaus.org/browse/MCOMPILER-179有关。尝试升级到Maven 3.0.5（或最新的3.1.x）或更新POM中maven编译器插件的版本。

为了详细说明这个主题，您可以使用showWarnings配置来强制显示编辑警告的开/关。

将其设置为false（如果它适合您），以便首先隐藏警告。

<plugins>
    <plugin>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.3</version>
        <configuration>
            <source>1.8</source>
            <target>1.8</target>
            <showWarnings>false</showWarnings>
        </configuration>
    </plugin>
</plugins>

确定。谢谢你们。我解决了将SuppressWarning("deprecation")添加到问题类的问题。但仍然不确定它对maven有什么不同..
